    The group of people aged 60 and over is expanding worldwide. Whereas the group aged over 80 years is growing fastest among all population segments. There is an increasing necessity to provide the elderly with balanced and functional nutrition aimed to maintain healthy aging and prevent diseases and, at the same time to cope with the special needs of people with masticatory and swallowing dysfunctions. This study outlines the current situation with elderly-oriented foods in Russia and the rapidly aging Japan. The study demonstrates that in Japan, there is a regulation system and commercial products tailored for older people, particularly those with dysphagia and/or need for special nutrition. However, providing appetizing and healthful products with a modified texture for the safe and nutritious diet of seniors remains an unresolved issue for the food industry in both countries. The study presents basic physiological disorders associated with food intake and specific aging-related nutritional needs to be considered when developing food for the elderly. Qualification of texture-modified products is given. A review of the recent research indicates that high pressure technology has feasible potential in developing healthy foods, including processed meat and fish products with reduced content of food additives, foods for the aging population, and people with dysphagia.

    © 2020 Published under licence by IOP Publishing Ltd. The effect of high hydrostatic pressure (HHP) treatment of 200 MPa for 10 min at room temperature in combination with salt (sodium chloride) and phosphate (sodium pyrophosphate) addition on the microstructure and sensory characteristics of beef gels were investigated. Sensory evaluation was involving students and staff of the Niigata University, using Scheffe's paired comparison method with grade. Gel microstructure was observed using scanning electron microscopy (JSM-6510LA, JEOL LTD., Japan). The free amino acid content of beef gels was analyzed by an amino acid analyzer (JLC-500/V, JEOL LTD., Japan). The results of sensory evaluation revealed that high pressure at 200 MPa improved the cohesiveness and springiness (elasticity) while significantly decreasing the softness in low salt and/or low phosphate beef gels (p < 0.05). Irrespective of the salt and/or phosphate content in the beef samples, panellists noted that the pressurized beef gels were firmer, more elastic, and more pleasant to bite. The scanning electron microscopy images revealed that high pressure treatment at 200 MPa produced a dense, homogeneous networked structure with small cavities for water retention in low salt beef gels. The total free amino acid content of low salt and/or low phosphate beef gels was increased by high pressure at 200 MPa (p < 0.05). The present study confirmed that high hydrostatic pressure at 200 MPa was effective in producing low salt and/or low phosphate beef gels while providing high quality textural and organoleptic properties.

    Recently, there has been a growing demand for healthy processed foods, such as comminuted or gel-type meat and fish products with reduced content of salt (sodium chloride), phosphate (sodium phosphate) and/or fat, while maintaining their texture and quality characteristics. As know, a high intake of dietary sodium is associated with cardiovascular diseases and strokes. On the other hand, high phosphate intake has a potential health risk, especially with regard to bone metabolism, cardiovascular and kidney diseases. High hydrostatic pressure (HHP) technology has been recognized as a useful method for successfully reducing salt, phosphate and/or fat content in processed muscle products. The texture, yield and organoleptic properties of products are closely related to the structure and functionality of myofibrillar proteins (MP). Application of moderate high hydrostatic pressure at 100–200 MPa has been successfully used to increase the functionality of myofibrillar proteins by modifying the structure due to denaturation, solubilization, aggregation or gelation. The ability to reduce sodium content and achieve a high binding and water retention using this technology is an important task for the production of healthy food products.

    © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group. The effect of high hydrostatic pressure (HHP) treatment (100–200 MPa, 10 min, 20°C) combined with sodium chloride and sodium phosphate on the physicochemical properties of beef gels was investigated. The water content, cooking losses, color, protein composition by SDS-PAGE analysis and texture parameters of beef gels were determined. The beef gels treated with high pressure at 150 MPa showed a synergistic effect in the increased water content and the decreased cooking losses compared with the unpressurized gels. The L*, a* and b* color values of beef gels were slightly decreased under HHP treatment at 100–200 MPa. In the SDS-PAGE analysis, the staining intensity of the α-actinin protein band was decreased in pressurized samples. The cohesiveness, adhesiveness, gel strength and modulus of elasticity were improved after HHP treatment. Application of high pressure treatment (150–200 MPa) before heat treatment would be beneficial for the manufacturing of low salt and/or low phosphate meat products for a healthy diet.

    The aim of this study was to determine the relationships among muscle fiber-type composition, fiber diameter, and myogenic regulatory factor (MRF) gene expression in different skeletal muscles during development in naturally grazing Wuzhumuqin sheep. Three major muscles (i.e. the Longissimus dorsi (LD), Biceps femoris (BF) and Triceps brachii (TB)) were obtained from 20 Wuzhumuqin sheep and 20 castrated rams at each of the following ages: 1, 3, 6, 9, 12 and 18months. Muscle fiber-type composition and fiber diameter were measured using histochemistry and morphological analysis, and MRF gene expression levels were determined using real-time PCR. In the LD muscle, changes in the proportion of each of different types of fiber (I, IIA and IIB) were relatively small. In the BF muscle, a higher proportion of type I and a 6.19-fold lower proportion of type IIA fibers were observed (P&lt;0.05). In addition, the compositions of type I and IIA fibers continuously changed in the TB muscle (P&lt;0.05). Moreover, muscle diameter gradually increased throughout development (P&lt;0.05). Almost no significant difference was found in MRF gene expression patterns, which appeared to be relatively stable. These results suggest that changes in fiber-type composition and increases in fiber size may be mutually interacting processes during muscle development.

    High hydrostatic pressure (HP) treatment is used in food processing owing to its sterilization effect. Meat or meat products are sterilized and become tender by HP processing. Therefore, the variety of HP-processed meat products has increased worldwide. However, little is known about the safety of HP-processed meat products. The aim of this study was to determine the effects of HP processing and HP combined with 0.4 M sodium carbonate treatment (HP-Na) on pork loins and to evaluate the subacute toxicity and cytotoxicity of these processing methods. In an in vivo study, we performed 90- and 180-day feeding tests in mice and did not detect any adverse effects in HP-processed and HP-Na-processed pork loins. In addition, we evaluated the cytotoxicity of HP-processed meats, and did not observe any obvious toxicity associated with pork loin extracts in vitro. These results suggest that HP is not associated with risk factors during processing.

    We found the feasibility of sterilization by applying a pressure treatment of 200 MPa before heat treatment. The wet density of spores of <i>Bacillus cereus</i> was decreased by the pressure history when we applied a high-pressure treatment of 200 MPa, and the heat resistance of the spores was decreased. Afterwards when we applied a heat at a medium-temperature of about 100℃, the sterilization of spores was promoted. Furthermore, we found the turbidity of the spore suspensions greatly decreased after the pressure reduction step of the high-pressure treatment. The decrease of turbidity was also found to be highly correlated with the survival spore counts after the heat treatment. Therefore the turbidity was considered to be a sterilization indicator.<br>

    The effects of high-pressure processing (HPP) (0-400 MPa for 10 min) on the cooking loss (CL), gel strength, and thermal gelling mechanism of chicken breast actomyosin solution containing 0.5 % (w/v) sodium alginate (AS-SA) were investigated. The results showed that HPP could significantly increase (P &lt; 0.05) the reactive sulfhydryl contents, surface hydrophobicity, and turbidity of the pressurized sample under 200-400 MPa and gradually decrease its thermal gelling ability with an elevating pressure from 100 to 400 MPa. The HPP under 300 MPa for 10 min could enhance the thermal stability of AS-SA and promote the formation of AS-SA gel structure with large pores and thick strands. Those resulted in the increased gel strength and the increased CL of pressurized AS-SA, which were relative to hydrophobic interaction and disulfide bonding. The information could offer certain theoretical foundation to apply HPP technology for developing meat-SA gels with various properties via combinational use of different HPP levels and SA.

    The effects of high pressure processing (HPP) (0-400 MPa for 10 min, 0-20 min under 300 MPa) on the water holding capacity (WHC) and gel strength of chicken breast myosin containing 0.225% kappa-carrageenan (W/V, 2.25 g/L relative to myosin solution) (myosin-K) and the thermal gelling mechanism were investigated. The results revealed that HPP at 100-400 MPa could significantly increase the WHC of myosin-K gels while decreasing the gel strength (P &lt; 0.05). The turbidity, surface hydrophobicity and reactive sulfhydryl contents of the pressurized myosin-K increased significantly at 200-400 MPa (P &lt; 0.05). Dynamic rheological measurements indicated that the thermal gelling ability of the pressurized myosin-K matrix gradually decreased as the pressure increased (100-400 MPa). Low-field nuclear magnetic resonance data suggested that HPP at 100-400 MPa might shorten the water relaxation time of the gel. The Fourier transform infrared spectroscopy data revealed that the hydrogen bonding interactions in the gels might weaken when subjected to 100-300 MPa but could be enhanced at 400 MPa. The scanning electron microscopy images revealed that HPP (300 MPa, 10 min) produced a dense, networked myosin-K gel structure with small cavities and thin cross-linked strands. Moreover, pressure levels were responsible for the above results. The protein in myosin-K could denature, unfold and aggregate under HPP (100-400 MPa), thus decreasing the thermal gelling ability of myosin-K matrix. The high WHC of the pressurized myosin-K gel was attributed to the enhanced hydrogen bonding and hydrophobic interactions, as well as the uniform and dense networked structure; the low gel strength might be ascribed to the low thermal gelling ability of pressurized myosin-K.

    The objective of this investigation was to evaluate the effects of L-histidine on the stability of porcine hemoglobin concentrates during storage. The results indicated that the addition of L-histidine increased the oxyhemoglobin content and a* values but decreased the methemoglobin content and free iron content (P &lt; 0.05) during storage. The addition of iron cation decreased both the oxyhemoglobin content and a* values but increased both the methemoglobin content and free iron concentration (P &lt; 0.05). CD spectra revealed that the free iron content induced the transformation of the hemoglobin secondary structure from an alpha-helix (close structure) to a beta-pleated, beta-turn, and random coil arrangement (loose structure), while L-histidine weakened this behavior of the free iron. Infrared spectra demonstrated that the L-histidine coordinated with the free iron (Fe2+ or Fe3+) to give the corresponding complex at 25 degrees C and pH 7.3. Therefore, L-histidine enhanced the stability of hemoglobin concentrates by coordinating with free iron. (C) 2014 Elsevier Ltd. All rights reserved.

    High pressure processing is able to tenderize not only meat but also intramuscular connective tissue, which is mainly composed of collagen. Decorin, one of the proteoglycans, binds to and stabilizes collagen fibrils. It has been suggested that structural weakening of intramuscular connective tissue may result from the disappearance of the decorin-collagen interaction. In this study, the fluorescence spectra and the surface hydrophobicity of decorin molecules were measured under high pressure in order to examine the resulting change in the tertiary structure. The fluorescence intensity and the surface hydrophobicity of decorin molecules both decreased with increasing applied pressure and with applied time at the constant applied pressure, respectively. The observations indicate that the native structure of decorin is maintained during 200MPa pressurization for less than 30min.

    Chicken breast is not preferred in Japan because it is not juicy. In this study, the effect of combined high pressure and sodium hydrogen carbonate (NaHCO3) treatment on the texture and palatability of chicken breast was investigated. The sample used was broiler chicken breast. Meat samples were soaked in.0-.4M NaHCO3 solution and then pressurized at 100-400MPa. After pressurization, the samples were heated for 30min at 80 degrees C and cooled down in ice-cold water. High pressure and NaHCO3 treatment of broiler chicken breast resulted in increased water content, and decreased weight reduction and rupture stress. Moreover, meat exposed to 200 MPa pressurization and.3M NaHCO3 treatment was judged tender, juicy and of good taste by sensory evaluation. The combination of high pressure and NaHCO3 treatment can be effectively used for broiler chicken breast production.

    In this study, the combined effects of high pressure and sodium hydrogen carbonate (NaHCO3) treatment on the physical and chemical properties, and palatability of pork ham, a tough and under-utilized meat, were investigated. Assessment of meat properties with heat treatment, after exposure to NaHCO3 and high pressure treatment, revealed an increase in water content, and decreased weight reduction and rupture stress. The free amino acid content of meat samples increased with NaHCO3 and high pressure treatment. The effect of high pressure processing was especially notable at a pressure of 300MPa. Sensory evaluation showed that meat subjected to high pressure processing after NaHCO3 treatment was tender and juicy. In addition, the sample produced minimal residue in the mouth and was characterized by a good taste.

    We investigated the effect of combined high pressure and sodium hydrogen carbonate (NaHCO3) treatment on the physical properties and color of silverside Australian beef. Meat samples were pressurized at 100-500MPa and the water content, weight reduction, rupture stress, and meat color were determined. The water content of meat treated with NaHCO3 and high pressure (300MPa) reached a maximum of 70.1%. Weight reduction tended to decrease with high pressure treatment at 300MPa. Meats treated with NaHCO3 and high pressure at 400MPa showed a&gt;50% decrease in hardness. Whitening of the meat was reduced by the combined high pressure and NaHCO3 treatment. Therefore, the combined high pressure and NaHCO3 treatment is effective for improvement of beef quality.

    Food wastes from households were treated with steam at 150 &deg;C for 40 minutes (150SFW) or at 200 &deg;C for 150 minutes (200SFW), and the possibilities of developing the resulting materials into livestock feeds were researched. Both SFWs were shown to be composed about 20% of proteins and 20% of lipids, which are higher than the ratios of commercial diets for finishing pigs. On the other hand, pepsin digestibility of both SFWs was 26-56%, which was lower than that of a commercial diet. To estimate the applicability of SFWs as feed, eight pigs, each weighing approximately 70kg, were divided into test and control groups of four pigs each. In the test group, the pigs were fed diets that were 20% 200SFW for an initial 29 days and were subsequently fed diets that were 15% 150SFW until they reached 110&plusmn;5kg. Pigs were fed diets without SFWs in the control group. The daily gains (DG) of two pigs in the test group were similar to those of pigs in the control group through the test period. The other two pigs in the test group had relatively lower DG when 200SFW was given, but ultimately reached 110&plusmn;5kg 29-46 days later than pigs in the control group.

    P252, a 252-kDa Bombyx mori protein located on the larval midgut membrane, has been shown to bind strongly with Bacillus thuringiensis Cry1A toxins (Hossain et al. Appl Environ Microbiol 70:4604-4612, 2004). P252 was also shown to bind chlorophyllide (Chlide) to form red fluorescence-emitting complex Bm252RFP with significant antimicrobial activity (Pandian et al. Appl Environ Microbiol 74:1324-1331, 2008). In this article, we show that Cry1A toxin bound with Bm252RFP and Bm252RFP-Cry1A macrocomplex, with both antimicrobial and insecticidal activities, was formed. The insecticidal activity of Bm252RFP-Cry1Ab was reduced from an LD(50) of 1.62 to 5.05 mu g, but Bm252RFP-Cry1Aa and Bm252RFP-Cry1Ac did not show such reduction. On the other hand, the antimicrobial activity of Bm252RFP-Cry1Ab was shown to retain almost the same activity as Bm252RFP, while the other two complexes lost around 30% activity. The intensity of photo absorbance and fluorescence emission of Bm252RFP-Cry1Ab were significantly reduced compared to those of the other two complexes. Circular dichroism showed that the contents of Cry1Ab alpha-helix was significantly decreased in Bm252RFP-Cry1Ab but not in the other two toxins. These data suggested that the reduction of contents of alpha-helix in Cry1Ab affected the insecticidal activity of the macrocomplex but did not alter the antimicrobial moiety in the macrocomplex of Bm252RFP-Cry1Ab.

    The effects of a high-pressure treatment on the IgE-specific binding activity and structural changes to bovine gamma globulin (BGG), a beef allergen, were investigated. The allergenicity of pressure-treated BGG was also evaluated. We found that the IgE-specific binding activity and allergenicity of BGG were decreased by the high-pressure treatment. Almost no significant change in secondary structure was apparent for pressurized BGG, but a change in the tertiary structure was detected. The decreased IgE-specific binding activity and allergenicity of pressurized BGG were probably due to changes in the tertiary structure caused by pressurization. The results of this study suggest that a high-pressure treatment would be an effective food-processing technique to reduce the allergenicity of BGG.

    In this study, the effects of high-pressure treatment on structure and allergeincity of alpha amylase inhibitor (a-AI) were investigated. The pressure-induced structural changes of α-AI were estimated by fluorescence spectra and by fourth derivative UV-spectroscopy for probed tyrosine residues and by circular dichroism (CD) spectroscopy. The changes in the tertiary structure detected by fluorescence spectra and by fourth derivative UV-spectroscopy under high pressure were indicated at over 300 MPa. Measurements of CD spectroscopy suggested that the effects of a high-pressure treatment on changes in the secondary structure of α-AI were little. From our results, pressure-induced changes of the α-AI structure were not apparent. On the other hands, the IgE-specific binding activities of pressurized α-AI to sera from allergic patients against wheat, which is estimated by observations of dot-blotting, were decreased by high-pressure treatment. It is known that the pressure-induced elimination of allergenicity is related to the tertiary structural changes of allergen molecules. This study are suspected that the epitopes of α-AI do not contain tyrosine residues, and thus the decrease of IgE-specific binding activities is probably caused by the tertiary structural changes of these parts of α-AI. © 2010 IOP Publishing Ltd.

    The present paper describes the effects of pressure and post-mortem aging treatments on in situ proteasome activity in rabbit and bovine skeletal muscles. Synthetic peptide hydrolyzing activity of rabbit proteasomes remained in the muscle after exposure to pressures up to 100 MPa. However, when a pressure of 400 MPa or more was applied, proteasomes were markedly inactivated. The extraction of proteasomes from excessively pressurized muscle appeared to be difficult. Proteasomes in aged muscle remained relatively stable throughout the aging process, with activity after 168 h (7 days) being 35%, 48%, 53% and 31% of the 0 h post-mortem LLVY, LSTR, AAF and LLE total hydrolyzing activities, respectively. The synthetic peptide hydrolyzing activities of bovine muscle proteasomes were similar to those of rabbit skeletal muscle proteasomes. The results suggest that synthetic peptide hydrolyzing activity remains in muscle exposed to relatively low pressures. Furthermore, it is known that high-pressure treatment induces fragmentation of myofibrils, modification of actin-myosin interaction and activation of intramuscular proteinases, cathepsins and calpains. Thus, proteasomes are probably involved in the tenderization process in combination with other intramuscular proteinases under high-pressure conditions. Our findings confirmed that proteasomes play a role in meat tenderization induced by high-pressure treatment or aging.

    The epithelial cell membrane 252-kDa protein (P252) isolated in our laboratory from Bombyx mori midgut was shown to bind strongly with Cry1Aa, Cry1Ab, and Cry1Ac toxins of Bacillus thuringiensis (15). In the current paper, P252 was shown to bind with chlorophyllide (Chlide) to form red fluorescent protein (RFP) complex, termed Bm252RFP, with absorbance and fluorescence emission peaks at 600 nm and 620 nm, respectively. P252 at a concentration of 1 mu M is shown to bind with about 50 mu M Chlide in a positively cooperative reaction to form Bm252RFP under aerobic conditions and in the presence of light at 37 degrees C. Various parameters influencing this reaction have been optimized for efficient in vitro chemical synthesis of Bm252RFP. Circular dichroism spectra revealed that P252 is composed of a P-structure (39.8% +/- 2.2%, based on 5 samples) with negligible contribution of alpha-helix structure. When bound to Chlide, the P-structure content in the complex is reduced to 21.6% +/- 3.1% (n = 5). Since Chlide had no secondary structure, the observed reduction suggests significant conformational changes of P252 during the formation of Bm252RFP complex. Bm252RFP had antimicrobial activity against Escherichia coli, Serratia marcescens, B. thuringiensis, and Saccharomyces cerevisiae with 50% effective concentrations of 2.82, 2.94, 5.88 mu M, and 21.6 mu M, respectively. This is the first report ever to show clear, concrete binding characteristics of the midgut protein to form an RFP having significant antimicrobial activity.

    Effects of high pressure treatment on the structure of connectin, one of the elastic protein of muscle were investigated by spectrometric analyses. Circular dichroism spectra show abundance of &beta;-structure in the secondary structure of connectin, whereas &alpha;-helix content was less than 10%. No significant change in secondary structure was observed in the connectin pressurized up to 400 MPa, but significant decrease of &beta;-sheet and increase of turn were observed in the connectin pressurized at 600 MPa. From the measurements of fluorescent spectra and center of spectral mass, it seems that the changes in the tertiary structure of connectin induced by relatively mild pressure of 100~200MPa were reversible, but the changes become irreversible with more higher pressure applied.

We also investigated the allergenicity of pressurized BGG. We found that the IgE-specific binding activity and allergenicity of BGG were decreased by high pressure treatment. Almost no significant changes in secondary structure were observed for pressurized BGG, but changes in the tertiary structure were seen. Therefore, decreases in the IgE-specific binding activity and the allergenicity of pressurized BGG are probably due to changes in the tertiary structure caused by pressurization.

From changes in the fluorescence and circular dichroism (CD) spectra, and in the aliphatic surface hydrophobicity of pressurized &alpha;-actinin, it seems that the changes in the structure of &alpha;-actinin pressurized to over 400 MPa are irreversible. We found that the SPPT-enhancing activity of &alpha;-actinin and the STTP-associated ATPase activity were more or less lost from &alpha;-actinin pressurized to about 400 MPa, and the addition of &alpha;-actinin pressurized to over 300 MPa increased the viscosity of an actin solution only slightly, so it seems that the SPPT-inducing activity of &alpha;-actinin is highly correlated with its actin gelation activity, rather than with its ATPase acceleration activity. The results of this study will be useful for better understanding the mechanisms underlying pressure-induced meat tenderization.

    The effect of high hydrostatic pressure on collagen fibril formation was investigated. The turbidity curve for collagen fibrillogenesis, the surface hydrophobicity of collagen molecules, and the ultrastructure of collagen fibrils were studied. Although high-pressure treatment before fibrillogenesis had no effect on the rate of fibril growth, the treatment produced a denser network of collagen fibrils. High-pressure treatment after fibrillogenesis produced a looser network. Collagen fibrillogenesis was inhibited by pressurization to less than 200 MPa and accelerated by pressurization to more than 300 MPa. The surface hydrophobicity of the collagen molecules decreased with increasing pressure. Different pressures affected collagen fibril formation differently.

    This paper describes the effects of pressure and postmortem aging treatments on the <I>in situ</I> postmortem activity of rabbit and bovine muscle. Rabbit proteasome retained their ability to hydrolyze synthetic peptides in muscle exposed to pressures of up to 100 MPa. However, when pressures of 400 MPa or more were applied, proteasome were markedly inactivated. The ability of the bovine proteasome to hydrolyze synthetic peptides was retained in muscle exposed to pressures of up to 200 MPa. However, when a pressure of 500 MPa or more was applied, the proteasome were markedly inactivated. We found that proteasome were difficult to extract from excessively pressurized meat. The results of this experiment show that muscle that is exposed to low-pressure pressurization retains its ability to hydrolyze synthetic peptides. This finding implies that proteasome are involved in the high-pressure tenderization process, in combination with other intramuscular proteinases.

    As meat conditioning progresses, cathepsins entrapped in the lysosomes of living muscle are gradually liberated into the cytosol. High-pressure treatment, a technique for reducing the conditioning period and improving meat tenderness, accelerates the liberation of cathepsins from lysosomes. We found that in rabbit muscle high pressure induced drastic changes in the localization of cathepsins, with concomitant modifications of lysosomes.

    Changes in shear force value, transverse sections, myofibrils and intramuscular connective tissue of bovine skeletal muscle exposed to the combination of high-pressure up to 400 MPa and heat (30 and 60 degrees C) were studied. The shear force value decreased by pressure-heat treatment up to 200 MPa at 30 and 60 degrees C, and then slightly increased over 200 MPa at 30 degrees C. Shear force values of treated muscles were lower than those of untreated ones. Gaps between muscle fibers in the untreated muscle were a little clear, and then they became very clear in the treated muscles up to 200 MPa at 30 and 60 degrees C. However, the gaps reduced significantly over 200 MPa at 30 degrees C. The remarkable rupture of 1-band and loss of M-line materials progressed in the myofibrils with increasing pressure applied. However, degradation and loss of the Z-line in myofibrils observed in the muscle treated at 60 degrees C was not apparent in the muscle treated at 30 degrees C. The length of the sarcomere initially contracted by pressure-heat treatment of 100 MPa at 30 degrees C seemed to have recovered with increase of the pressure up to 400 MPa. In the muscle treated at 60 degrees C, the length of sarcomere gradually decreased with increase of the pressure up to 400 MPa. In the treated muscles, changes in the honeycomb-like structure of endomysium were observed and accelerated with increase of the pressure. A wavy appearance clearly observed at the inside surface of endomysium in the untreated muscles gradually decreased in the treated muscles with increase of the pressure. Tearing of the membrane was observed in the muscles treated over 150 MPa at 30 degrees C, as observed in the sample pressurized at 100 MPa at 60 degrees C. The roughening, disruption and fraying of the membrane were observed over 200 MPa at 60 degrees C. From the results obtained, the combination of high-pressure and heat treatments seems to be effective to tenderize tough meat. The shear force value may have some relationship with deformation of intramuscular connective tissue and myofibrils.

    The objective of this study was to investigate the effects of sodium alginate (SA) and pressurization levels on pH, water-binding and textural properties of pork muscle gels (PMG) containing salt. Ground lean pork with 1.0% NaCI and a given amount of SA (0.25, 0.5, 0.75 and 1.0%, respectively), was pressurized to 100, 200 or 300 MPa and subsequently gelled by heating. Results showed that addition of SA into pork muscle enhanced water-holding capacity (WHC) of PMG (p &lt; 0.05) as SA increased from 0.25% to 1.0%, with pH slightly increased (p &gt; 0.05). A decrease (p &lt; 0.05) was observed in all textural parameters (hardness, cohesiveness, springiness and chewiness). Pressurization had no effect on the tendency of WHC to increase or the decrease of the textural parameters. However, the effectiveness of pressurization to enhance textural properties of PMG was significant at some SA levels, especially &gt;= 200 MPa and at &lt;= 0.75% SA levels. Different combinations of pressure and SA levels could bring about variation in textural properties of PMG while SA enhanced WHC of pork muscle. The multiformity of the texture will open up a wide range of technological possibilities for the manufacture of pork-based restructured low-fat products.

    The effect of high-pressure treatment on bovine intramuscular connective tissue was investigated under various pressures (0.1 to 500 MPa) at 8 degrees C for 5 min. Shear force value, heat solubility of collagen, and structural changes of pressurized intramuscular connective tissues were evaluated. High hydrostatic pressure tenderized bovine intramuscular connective tissue as well as meat. The heat solubility of collagen increased (P &lt; 0.05) with high pressure, which indicates a reduction of collagen thermal stability. However, high pressure could not degrade collagen molecules by sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis. Collagen-derived peptide analysis also suggested that high pressure could not degrade the molecular structure of collagen, but could dissociate the collagen fibers or fibrils into fibrils or molecules. Histological study showed that high pressure induced structural weakening of intramuscular connective tissue, especially perimysium.

    The commercial-scale feasibility of high-pressure treatment to fermented foods was investigated, with attention given to the fact that the pressure resistance varies with the kind of microorganism. Kimchi was chosen because lactic acid bacteria had been found to be separated from yeast by pressure application of 300 MPa (20&deg;C), and subjected to pressure treatment to investigate the microbiological, physicochemical and sensory changes with the progress of fermentation. Pressure application of 300 MPa (20&deg;C) to Kimchi for 5 minutes slightly decreased the number of lactic acid bacteria, while completely inactivated the yeast to prevent expansion of the Kimchi-containing package during the storage. The pressure treatment also reduced the generation of lactic acid, the drop in pH value and the decrease of glucose and fructose contents. Although the pressure-treated Kimchi showed increased color difference and translucence, the breaking stress was not changed. The sensory tests demonstrated the advantages of pressure-treated Kimchi, to confirm the improvement of shelf life of Kimchi.

    Changes in the localization of calpain in conditioned and pressurized bovine skeletal muscles were investigated by immunogold electron-microscopy. In the muscle immediately after thawing (control), the relative distributions of colloidal particles statistically calculated by counting the colloidal particles were about 65% and 35% in the I-band/Z-disk and A-band regions, respectively. In the muscle conditioned for 7 days, distribution of colloidal particles was more than two times greater in both the I-band/Z-disk and A-band regions than in the control muscle. Almost no change in either the absolute concentration or relative distribution of the colloidal particles was detectable during further storage. In the muscle exposed to a pressure of 100 MPa or, 200 MPa, slightly more immunogold was detected in the sarcomere than in that of the control muscle. Increasing pressure up to 300 MPa enabled high-density particles to be seen throughout the sarcomere. Conversely, few particles were detected in the sarcomere of the muscle exposed to 400 MPa. These electron-microscopic observations were confirmed from the statistical analysis as with the conditioned muscles. It was clear from the results obtained that the pressure-induced changes in calpain localization were much;more pronounced than those from conditioning.

    This paper describes general methods to eliminate or decrease the allergenicity of food protein, and also describes high pressure-induced elimination of the allergenicity of food protein, especially meat protein.The effect of high pressure treatment on the elimination of bovine serum albumin (BSA, the major beef allergen) allergenicity was evaluated on the basis of histamine release from human basophilic KU812F cells sensitized with sera from allergic patients, and the structural changes of BSA responsible for reducing allergenicity was estimated. BSA pressurized at pressures ranging from 300 to 600 MPa reduced histamine release from the cells sensitized with A5 serum with significance. The reducing effect of high-pressure treatment gradually increased with the increase of pressure applied to BSA. The pressure-induced structural changes of BSA were estimated by fluorescence spectra, circular dichroism (CD) spectra (the content of secondary structure), the amount of surface sulfhydryl (SH) group, and the surface aromatic hydrophobicity. The blue shift and decrease of the fluorescence of BSA gradually progressed with the increase of pressure applied. But no significant effect of pressure on CD spectra was observed. Pressure-treated BSA showed the maximum increase in the amount of SH group by pressure treatment at 100 MPa, and the aromatic hydrophobicity gradually decreased with the increase of high pressure applied. These results indicated that high pressure treatment induced the tertiary structural changes of BSA, but no effect on the secondary structure. We concluded that the pressure-induced elimination of BSA allergenicity seemed to be related to the tertiary structural change of BSA.

    The effects were assessed of high hydrostatic pressure on the activity and structure of rabbit skeletal muscle proteasome. The pressure effects on the activity were measured by the amount of fluorometric products released from synthetic substrates under pressure and from fluorescein isothiocyanate (FITC)-labeled casein after releasing the pressure. The effects on the structure were measured by fluorescene spectroscopy under pressure, and by circular dichroism (CD) spectroscopy and surface hydrophobicity after releasing the pressure. The optimal pressure for the hydrolyzing activity of synthetic peptides was 50 MPa. The degradation of FITC-labeled casein increased linearly with increasing pressure applied up to 200 MPa, and then markedly decreased up to at 400 MPa.
    The changes in the tertiary structure detected by fluorometric measurement were irreversible, whereas the changes in the secondary structure were small compared with those by heat treatment. The pressure-induced activation of proteasome therefore seems to have been due to a little unfolding of the active sites of proteasome.

    Calpain and calpastatin activities were investigated in calcium-treated beef after osmotic dehydration. Dehydrated beef was soaked in 150 mM calcium chloride solution for 3 h, and then stored for 48 h at 3-4 degrees C. The untreated sample (control) was soaked in deionized water for 3 h instead of calcium chloride solution, after osmotic dehydration. The increase and decrease in the relative activity of crude calpain were observed in the untreated and the calcium-treated meat, respectively, during the storage. When the crude calpains were subjected to DEAE-Sephacel column chromatography, it was found that mu-calpain activity decreased rapidly during the storage in the untreated meat, whereas there was almost no change in the activity of mu-calpain during the storage. The decrease of calpastatin activity was moderate compared with the decrease of mu-calpain activity. In the calcium chloride-treated meat, however, no mu-calpain nor calpastatin activities was detectable after 48 h at cold-room temperature, and m-calpain activity after 48 h had decreased to 6.1% of its activity immediately after thawing. It was concluded that 150 mM calcium chloride treatment after osmotic dehydration was sufficient to introduce calcium ions into the meat. In the presence of sufficient calcium, autolysis of calpains and proteolytic degradation of calpastatin, which eventually related to the rate of decrease in calpain and calpastatin activities, clearly seem to be related to a decrease in meat toughness.

    We previously demonstrated that a novel 252-kDa protein (P252) isolated from brush border membranes (BBM) of Bombyx mori, hybrid Shurei X Shogetsu, specifically bound Cry1Aa, Cry1Ab and Cry1Ac toxins with a Kd of 29, 179 and 20nm, respectively. P252 was found in a Triton X-100-soluble fraction of BBM from first, third and fifth instar larvae, suggesting that it may be an important element of midgut epithelial cell membranes. P252 was not partitioned into a Triton X-100-insoluble BBM fraction and nearly identical partitioning of P252 was observed using detergents CHAPS and Igepal. These results suggested that P252 localized in non-raft regions of BBM. Immunofluorescence analysis using anti-P252 antiserum demonstrated the existence of P252 in BBMV Cy3-labeled Cry I Aa, Cry I Ab and Cry1Ac were shown to bind to BBMV, and the addition of anti-P252 antiserum reduced the number of BBMV showing Cy3 fluorescence by 30%. This clearly suggested an important role for P252 in Cry1A binding to BBMV CD spectra of a mixture of purified P252 with either Cry1Aa, Cry1Ab or Cry1Ac were compared with those of respective free Cry1A toxins and only one of the mixtures (Cry1Aa/P252) was shown to be significantly changed compared to that of native Cry1Aa.

    This paper describes the purification and properties of a multicatalytic proteinase complex, proteasome, from bovine skeletal muscle, in comparision with proteasome prepared from other species or organs. The purified bovine skeletal muscle proteasome exhibited a single band on polyacrylamide gel electrophoresis under nondenaturing conditions. Bovine skeletal muscle proteasome degraded synthetic peptides maximally at pH 8.0. Relative to pH 8.0, activities were gradually decreased with the lowering pH, but the extent of decrease was substrate-dependent, and the activity at pH 5.5 still retained 78-10% of the activity at pH 8.0, indicating the possibility that the proteasome is active in muscle during aging. When the proteasome was heated at 60°C for 15 or 30 min and treated in the presence of 0.0125% SDS, the activity increased over 1.8 and 3.1 times (LLVY (Suc-Leu-Leu-Val-Tyr-NH-Mec) as a substrate), respectively. These results (activation with heat or SDS) indicate that the hydrolytic activity of proteasome was stimulated under mild denaturing conditions. The characteristics of the bovine skeletal muscle proteasome obtained in our experiment were almost the same as those of the proteasome prepared from other species or organs.

    The changes in morphological structure of intramuscular connective tissue and transverse sections between muscle fibers of bovine skeletal muscle exposed to the combination of high pressure (100-400 MPa) and heat (30degreesC) were studied using a scanning electron microscope. In the raw meat and in the treated muscles at 100, 150 and 200 MPa, the gaps between fibers and endomysial tubes were very clear. However, with increasing pressure to 300 and 400 MPa, the gaps became much closer. In the treated muscles, structural changes in the endomysium and perimysium, especially deformation of honeycomb-like structure of endomysium, were observed and accelerated with the increase of the pressure. A wavy appearance was clearly observed at the surface of endomysium in untreated muscles. However it gradually decreased and disappeared in treated muscles. Tearing and roughening of the membrane were observed in the muscles treated over 150 MPa. The shear force value decreased by high-pressure and heat treatment up to 200 MPa and then slightly increased. However the shear force values of treated muscles were lower than those of the untreated ones. From the results, it seems that the application of high pressure at 30degreesC causes some deformation of intramuscular connective tissue. This deformation may have some relationship with the gaps between fibers and endomysial tubes.

This deformation may have some relationship with the gaps between fibers and endomysial tubes.

    Changes in the localization of cathepsin D in postmortem and pressurized rabbit muscles were investigated by immunoelectron microscopy. The anti-cathepsin D monoclonal antibody strongly labeled a large vesicle in a subsarcolemmal part of the cell, which strongly suggests that this is the primary lysosome. The liberation of the cathepsin D entrapped in the lysosomes in the muscle prepared immediately after death proceeded with the progress of the conditioning. The release of almost all cathepsin D from the lysosomes and its absorption on the myofibrils were observed in the muscle conditioned for 14 days. The accumulation of lysosomes having various volumes and shapes accompanied with the disruption of myofibrillar structure was also observed. The liberation of cathepsin D from the lysosomes can be attributed to the modification of membranes permeability of the lysosomes during conditioning. When the muscle was pressurized at 100 MPa, the modification of the round shape of the lysosome was observed. With the increase of the pressure applied to the muscle, the release of cathepsin D from the lysosome due to the disruption of membrane was accelerated, and absorption of the released cathepsin D on the myofibrils was observed. From the results obtained, it was clear that the changes in the localization of cathepsin D accompanied with the modification of lysosomes induced by the brief exposure to high pressure were drastic in comparison with that in the muscle during conditioning.

    In this study, meat was tenderized by dipping the meat in a calcium-containing solution after osmotic dehydration. Dehydrated meats were dipped in a 150 mM calcium chloride solution for 3 h, and after that stored for 24, 48, and 168 h at 3 similar to 4degreesC. Then, meat was subjected to texture measurement, sensory evaluations, biochemical analysis and histological observations. A gradual decrease in the firmness and higher tenderness sensory scores were observed in the meat treated with calcium chloride as compared with the untreated meat. Few differences were observed in water holding capacity by treatment at any stage of storage. A gradual increase in the myofibril fragmentation from the calcium chloride-treated meats was observed throughout the storage compared with the controls. Broadening of the I band and a disordered Z-line were observed in the treated meat. The deformation of the honeycomb-like structure of the endomysium was also observed in the treated samples. Therefore, the dipping in 150 mM calcium chloride solution after dehydration can be applied to improve meat tenderness without detrimental effects on other palatability and quality traits.

    This paper describes the effects of high hydrostatic pressure treatment on the structure and activities of rabbit skeletal muscle proteasome.
    It was cleared that the high pressure treatment up to 50similar to100 MPa caused the activation of the proteasome as observed in the mild denaturing treatment with SDS, heat etc. This activation is probably due to the increase of the interaction of the substrate and active site of the proteasome unfolded by high pressure treatment.

    In the present investigation, proteoglycan associated with porcine intramuscular collagen fibrils was isolated and characterized. The increase in the values of released uronic acid (percent) and heat solubility of collagen (percent) was observed by chondroitinase ABC digestion of intramuscular connective tissue isolated from porcine longissimus dorsi muscles, indicating that collagen fibril-associated proteoglycan was involved in the thermal stability of intramuscular collagen. A proteoglycan was purified from the adult porcine intramuscular connective tissue by successive steps of an extraction with 4 M guanidine hydrochloride, CsCl density gradient ultracentrifugation, DEAE-cellulose ion-exchange chromatography, and Sepharose CL-6B gelfiltration. The isolated proteoglycan possessed an average molecular mass of 100 kDa and contained a core protein with mass of 48 kDa. Its constituent glycosaminoglycan chain was a dermatan sulfate, and the N-terminal amino acid sequence of its core protein was identical to that of small proteoglycan (PG-II) from other tissues. These results indicate that the collagen fibril-associated proteoglycan isolated from adult porcine intramuscular connective tissue was the small proteoglycan containing a dermatan sulfate chain (DS-PG-II), namely decorin.

    加熱処理は,食品の保存・調理・加工のために太古から広く用いられてきた方法である。一方,食品への高圧処理は1987年に初めて日本で提唱されたもので,加工技術としてはまだ30年しかたっていない。しかしながら,非加熱的な食品加工(non-thermal food processing)技術の1つとして,数千気圧(数百MPa)の静水圧を利用する高圧処理技術が注目されている。高圧処理の一番の特徴は,食品の大きさ,形状,成分などに依存せず,食品の中心にまで瞬時に圧力の効果が伝えられることである。また,加熱に比べて高圧力のエネルギーはとても低く,同等効果を期待した場合で加熱の約1/10以下のエネルギー消費と考えられ,しかも圧力保持中にはエネルギーがかからない。高圧処理は,まだ一般にはなじみの少ない加工技術であるが,上記に加え,微生物の生育抑制・殺菌に役立つことに注目されて研究開発が進められ,さらには栄養分の損失や異臭・異常物質の発生がないことなどから,近年では保存料などの食品添加物をできるだけ減らしつつ賞味期限の延長を図るようなナチュラル志向食品への利用が進み,世界中で様々な高圧加工食品が市販されている。また高圧処理は,加熱と同様に,食品中のタンパク質や澱粉などの生体高分子の立体構造を変化させ,変性を誘導する。しかし,高圧処理に伴う生体高分子の変性挙動は,分子運動の激化による変性を導く加熱処理とは異なる。食品素材を構成する生体成分,特に生体高分子といわれるタンパク質や多糖や脂質や核酸などは,水などの溶媒とともに非共有結合を使って立体的な全体構造を作っている。このような生体高分子に静水圧を施すと,系全体の体積を減らす方向に変化が起きるため,その立体構造が変化し,さらに圧力を増すと不可逆的に変性する。この原理はあらゆる食品・食品素材の物性や機能性に影響を及ぼし,例えば,澱粉の糊化・老化,食品の保水性・結着性・ゲル強度といった食感や物性の改良,さらには酵素反応の制御などに適用できるが,市販されている高圧加工食品への利用例はまだ少ないのが現状である。本稿では,食品加工への高圧処理技術のさらなる利用性の発展を鑑み,高圧処理によるタンパク質の変性・改質ならびにこれを応用した食品開発(食品の高品質化)に関して,高タンパク質食品である食肉での成果を例に挙げて紹介する。

    High pressure can accelerate post-mortem aging of meat, which results in improving meat tenderness. High hydrostatic pressure modifies conformation of intramuscular protein molecules, disorganizes the supermolecular structure, and then induces the structural weakening of myofibrils and intramuscular connective tissue. Although the effect of high-pressure processing on meat tenderizations is limited after cooking of meat, combining high pressure with sodium hydrogen carbonate treatments can improve texture and palatability of cooked meat and meat products. Science and technology of the high pressure processing for meat texture will be reviewed.<br>

    This paper describes the application of high-pressure treatment from a viewpoint of industrial utilization. High-pressure treatment induces the transformation of agricultural and livestock products, and this &ldquo;pressure history&rdquo; (the influence of high-pressure treatment) has an effect on later processes. A later enzymatic reaction is promoted by the destruction of the cell walls, even in post-harvest farm products. In addition, the heat-resistant spores decreased after receiving a high-pressure treatment of 200 MPa before heating sterilization, and even heating at 100℃ to 105℃ showed that food could still be sterilized.<br>

    Mechanical, biochemical and histological evaluations of natural hog and sheep casings were studied to elucidate the effect of connective tissue on the mechanical properties of natural casings. Chinese casings were significant tougher than any other casings (p<0.01). Natural hog and sheep casings were predominantly composed of collagen organized in many layers of sheets of collagen fibers and minor elastin limited in blood vessels. The amounts of collagen, elastin, and proteoglycan, and histological distribution and density of elastin fibers for various casings were essentially the same. These parameters thus would not likely contribute to the strength of natural casings. Chinese casings possessed a significant low heat-solubility of collagen (p<0.01), and a different size and arrangement of collagen fibers. Thus the thermal and structural stabilities of collagen may determine the mechanical properties of casings.

    Language:English   Publisher:Japanese Society of Animal Science  

    Shear force value, contents of intramuscular collagen, elastin and proteoglycans and heat solubility of collagen were determined on eight different muscles from miniature pigs in order to confirm the relationship between raw meat toughness and intramuscular connective tissue components. <i>Semitendinosus </i>and <i>semimenbranosus</i> muscles were significantly tougher than any other muscles tested (P<0.05). The strongest correlations (P<0.001) were found between elastin content or heat solubility of collagen and raw meat toughness. No meaningful links could be found between textural quality of the raw meat and heat-labile collagen content or the proportion of ground substance relative to fibrous connective tissue (P>0.05). Significant differences were seen, however, between the total collagen or proteoglycan content and the relative tougness of each muscles (P<0.01, P<0.05), respectively.<br>The results suggest that the maturity of intramuscular collagen with a stable intermolecular cross-linking and the accumulation of elastin may be directly contributing to meat toughness.

    Language:Japanese  

    In order to elucidate the qualitative disposition and the quantitative distribution of the aromatic constituents in roughage, the volatile constituents of the green forage and hay of bahiagrass were analyzed by a combined gas chromatograph-mass spectrometer (GC-MS) and a FID-gas chromatograph (FID-GC). The area percentage of each compound in the volatile constituents and the parts per billion (ppb) concentration of each compound in the materials were calculated on a data processor for FID-GC using n-pentadecane as the internal standard. As a result, 25 compounds were identified from the volatile constituents of the green forage of bahiagrass; their area percentages and ppm values totaled 78.2 and 22.0, respectively. The volatile constituents of this green forage were quantitatively rich in alcohols, esters, and ketones. On the other hand, 26 compounds were identified from the volatile constituents of the hay of bahiagrass; their area percentages and ppm values totaled 79.4 and 12.0, respectively. The volatile constituents of this hay were also rich in alcohols, esters, and ketones. Both volatile constituents were qualitatively about the same, but were somewhat different quantitatively.

    Journal of the Faculty of Applied Biological Science,Hiroshima University   30 ( 2 )   p103 - 111   1991.12

     More details

    Language:Japanese  

    Morphological changes in dermal collagen fibers in growing mink were investigated using a scanning electron microscope (SEM). The SEM view of dermal collagen fibers varied throughout the newborn, growing and mature skin phases. The reticular layer of newborn mink dermis was plate-like, and appears to be composed of fine collagen fibers, proteoglycans and glycoproteins. With mink growth, randomly entangled dermal collagen fibers, which were relatively fine and curled or waved, showed regularity of the three-dimensional network. A three-dimensional network of thick collagen fibers was observed in the mature mink dermis, and the fiber arrangement altered in relation to the depth from the epidermis, i. e., in the upper dermis, many fibers were arranged diagonally to the skin surface, whereas in the mid and deep dermis, thick fibers were conspicuously arranged parallel to the skin surface. The collagen fiber network was formed by repeated branching and anastomosis of the fibers. There were thin elastic fibers in the dermal-epidermal junction and between the collagen fibers and skin appendages.

    Language:Japanese  

    The binding ability of bovine milk proteins with mutagenic heterocyclic amine was investigated. Binding was determined with 2 mg of protein and 20 g of 3-amino-1, 4-dimethyl-5H-pyrido[4, 3-b]indole (Trp-P-1) in 0.4 ml of pH 7.4, 50 mM phosphate buffer, at 37°C, in a shaker for 10 min. The unbound Trp-P-1 in protein-free ultrafiltrate was prepared using Ultrafree UFC3LGC00 and was analyzed by HPLC method. The binding of whole casein, αs-casein, β-casein and κ-casein were 54,03, 40.02, 56.24 and 33.75%, respectively. β-Lactoglobulin A, β-lactoglobulin B, lactoperoxidase, lactoferrin-a and lactoferrin-b were 23.61, 17.87, 15.20, 22.53 and 6.92% respectively. However, α-lactalbumin could not bind Trp-P-1 in this experiment. The binding of these milk proteins which were prepared by ourselves were compared with purchased proteins. They showed similar tendency to our proteins.

    In order to elucidate the qualitative disposition and the quantitative distribution of the aromatic constituents in roughage, the volatile constituents of Italian ryegrass silage made in a steel silo were analyzed via a combined gas chromatograph-mass spectrometer (GC-MS) and a FID-gas chromatograph (FID-GC). The area percentage of each compound in the volatile constituents and the parts per billion (ppb) concentration of each compound in the silage were also calculated on a data processor for FID-GC using n-pentadecane as the internal standard. As a result, 26 compounds were identified from the volatile constituents of Italian ryegrass silage; their area percentages and ppm values totaled 98.3 and 1519.7, respectively. The volatile constituents of this silage were very rich in acids, of which n-butyric acid was the major constituent (79.8% and 1234ppm). Also, the acids in the solvent extract of this silage were analyzed via a GC-MS and FID-GC, and 18 carboxylic acids were identified. Similarly, n-butyric acid was the major constituent (55.3%).

    High hydrostatic pressure induces a structural weakening of intramuscular connective tissue. Decorin, one of a small proteoglycans, binds to and stabilizes of collagen fibrils. It has been suggested that the weakening of intramuscular connective tissue may result from alteration of decorin-collagen interaction due to the structural changes in decorin molecule. In the present study, decorin was isolated and purified from bovine skeletal muscle, and then the molecular structure of the isolated decoin under and after high pressure was investigated. The results were following: (1) Degradation of core protein and GAG chain of the isolated decorin was not revealed by high pressure. (2) Fluorescence spectra and surface hydrophobicity of the isolated decorin indicated that the tertiary structure of the decorin molecule was altered partially under high pressure up to 400 MPa. (3) High pressure did not affect the intramolecular disulfide bonds of the isolated decorin.

    High hydrostatic pressure tenderized bovine intramuscular connective as well as meat. Morphological study by scanning electron microscopy revealed that high pressure induced structural weakening of intramuscular connective tissue, especially collagen fiber networks in perimysium and perimysial-endomysial junction. Degradation of collagen molecules by high pressure could not be shown, while dissociation of collagen fibers or fibrils into fibrils or molecules could be found. High hydrostatic pressure can therefore not degrade the intramuscular collagen molecules but can weaken the association of collagen molecules and fibrils, which might be involved in tenderizing followed by structural weakening of intramuscular connective tissue.

    わが国の食物アレルギー患者数は年々増加している。食物アレルギーの原因となる食品24品目が指定され、食物アレルギーに対する正確な診断と適切な治療及び予防が緊急の課題になっている。本研究は、熱に代わる食品加工法として注目をあびている超高圧処理によりアレルゲン蛋白質の構造を操作することにより免疫系を含む生体を制御し、アレルギー反応を抑制することを目指している。得られた成果を以下に示す。
    牛肉アレルゲンタンパク質、γ-グロブリン(Bovine γ-globulin ; BGG)への影響
    1)BGGに100-600MPaの超高圧を加えたところ、牛肉アレルギー患者から得られた血清中のIgEとの結合性は処理圧力の増加に伴い減少した。また、患者血清に感作したヒト好塩基様細胞に超高圧処理したBGGを作用させたところ、好塩基様細胞から遊離するβ-ヘキソミニダーゼの活性は処理圧力が高くなる程、低くなる傾向が認められた。このことは、超高圧処理によって、BGGのアレルゲン性を低下させる可能性を示している。
    2)超高圧処理によるBGGの高次構造の変化をCDスペクトル、蛍光および紫外吸収スペクトル、疎水性基の反応性などにより測定した結果、BGGのエピトープ周辺の3次構造に、圧力による不可逆的な構造変化が起こり、これがアレルゲン性の低下をもたらすことが示唆された。
    卵白アレルゲンタンパク質、オボムコイド(OVM)に及ぼす影響
    1)超高圧処理したOVMの卵アレルギー患者血清IgG抗体およびIgE抗体との結合性はいずれも圧力が低い領域では圧力に依存して低下した。500,600MPaと圧力を上昇させるとIgG抗体との結合性は未処理OVMと変わらず、IgE抗体との結合性はむしろ増加した。加熱処理による変化は認められなかった。
    2)CDスペクトルの測定からOVMは圧力および熱処理に対して2次構造的に強固であるが、蛍光スペクトルの測定から3次構造的には不可逆的な変化を生ずる事が明らかになった。前述のBGGの場合と同様に、高圧処理による高次構造の変化が、IgG抗体エピトープおよびIgE抗体エピトープの変化を誘導し、抗体結合性を低下させたものと考えられる。即時型アレルギーの要因であるIgE抗体との結合性の低下はアレルゲン性の低下につながる。
    以上の結果から超高圧処理による畜産食品アレルゲン性低減化の可能性が明らかになった。この方法は他の食品アレルゲン性の低減化に役立つものと考えられる。

    The regulation of muscle protein by high pressure was investigated to elucidate the mechanism of pressure-induced meat tenderization and acceleration of meat conditioning focussing on the endogenous protease in the muscle. The elimination of meat allergenicity by high pressure and pressure effects on the enzymes producing taste-related components in the muscle were also investigated.
    1) Effect on tropomyosin and α-actinin
    (1)α-helix content of α-actinin decreased from 60% to 40% with the increase of pressure applied, while tropomyosin was resistive to high pressure.
    (2)Structural changes of α-actinin by high pressure seem to be reversible under 300 MPa and not reversible over 300 MPa.
    (3)Superprecipitation(SPPT)-inducing activity of α-actinin highly correlates with actin gelation activity, rather than that with ATPase acceleration.
    2)Combined effects of high pressure and heat
    (1)The combination of high pressure and heat treatments seem to be effective to tenderize tough meat.
    (2)The shear force value may have some relationship with deformation of intramuscular connective tissue and myofibrils.
    3)Effect on intramuscular connective tissue
    (1)Not only muscle fibrils but also connective tissue was tenderized by high-pressure treatment.
    (2)Pressure-dependent decrease of thermal stability and structural weakening of intramuscular collagen was observed.
    4)Effect on endogenous proteases in muscle
    (1)High pressure led to proteasome (one of endogenous proteases in the muscle) activation and irreversible change in the tertiary structure as detected from fluorescent measurement, whereas the change in the secondary structure was slight compared with that by heat treatment. Therefore pressure-induced activation of the proteasome seems to have been due to a small amount of unfolding of the active cites of proteasome.
    (2)Changes in the localization of calpain (one of endogenous proteases in the muscle) in conditioned and pressurized bovine skeletal muscles were investigated by immunogold electron microscopy. It was clear that pressure-induced changes in calpain localization were drastic in comparison with those during conditioning.
    5)Effect on allergenicity of bovine serum albumin (BSA)
    (1)The effect of high pressure treatment on the elimination of BSA was evaluated on the basis of histamine release from human basophilic KU812 F cells sensitized with sera from allergic patients, and the structural changes of BSA responsible for reducing allergenicity was investigated.
    (2)The reducing effect on the allergenicity gradually increased with the increase of pressure to BSA.
    (3)The pressure-induced elimination of BSA allergenicity seems to be related to the tertiary structural change of BSA.
    6)Effect on the enzymes producing taste-related components in the muscle
    Inosinic acid (IMP; one of the umami components) was produced in meat even by high pressurization, because the enzymatic properties of the enzymes producing taste-related components in the muscle were retained in pressurized meat.

    筋肉中のピリジノリン解析のために、まず、いくつかの筋肉内コラーゲン単離手法の比較検討を試みた。その結果、FujiiとMurota(1982)の生化学的抽出法を用いると精製度の高い筋肉内コラーゲンが高収率で得られたため、この方法に従って熟成4,7,10,14,21,28日目の19ヶ月齢ウシ胸最長筋から筋肉内コラーゲンを調製した。
    各熟成期間で得られた筋肉内コラーゲンを酸加水分解し、Eyreら(1984)の方法に従ってHPLCで分析した。市販のピリジノリンを内部スタンダードとして用いたところ、13.5分程度でピリジノリンが溶出し、また各々の筋肉内コラーゲンのクロマト展開図でもピリジノリンの明らかなピークが認められた。本研究において、19ヶ月齢ウシ胸最長筋中のピリジノリン含量は0.22〜0.34mg/gコラーゲン,すなわち0.14〜0.22モル/モルコラーゲンであり、以前のいくつかの報告と同様の値となった。一方、食肉の各熟成期間におけるピリジノリン含量は、熟成4日目;0.14〜0.18, 7日目;0.18〜0.22, 10日目;0.16〜0.21, 14日目;0.15〜0.18, 21日目;0.15〜0.21, 28日目;0.18〜0.22モル/モルコラーゲンとなり、食肉の熟成中におけるピリジノリン含量の変動が大きく、また食肉の熟成に伴う筋肉内ピリジノリンの明らかな変化は認められなかった。しかしながら、各熟成期間における筋肉内コラーゲンの収量にも同様の変化が認められていたことから、ピリジノリンによる筋肉内コラーゲン分子間の架橋程度が食肉の熟成に伴う筋肉内コラーゲン収量の変化に影響を及ぼしていることが示唆された。

  • 死後硬直に伴う筋肉内コラーゲン線維の立体構造の変化に関する研究

    Grant number:06760233

    ミニブタから採取後、4℃で0,2,6,12,24,72時間貯蔵した胸最長筋の硬さとpHの測定から、死後2〜12時間が死後硬直期,その後の解硬期を経て、死後24時間以降が熟成期であると確認された。
    一方、SEMによる筋肉内コラーゲン線維立体構造観察から、以下のような見解が得られた。すなわち、Ohtani et al.(1988)の報告した細胞消化法を用いると、筋線維が除去されることにより、筋肉内,特に筋線維に接した筋肉膜内側や筋周膜・筋内膜移行部のコラーゲン線維網が効果的に観察できた。死後硬直開始期(死後2時間)で、まず筋周膜・筋内膜移行部の構造が変化したが、筋周膜および筋内膜の構造的変化は認められなかった。硬直期では、筋内膜を構成するコラーゲン細線維ネットワークがかなり乱れ、コラーゲン細線維の癒着変性が進行した。また筋周膜・筋内膜移行部のコラーゲン線維同士の癒着も進行し、構造変化が大きくなった。一方筋周膜は、硬直期後半で全体構造にやや乱れが生じ、構成コラーゲン細線維の一部に癒着が認められた。解硬期以降、筋周膜・筋内膜移行部コラーゲン線維はほとんど消失し、筋内膜構成コラーゲン細線維ネットワークもかなり空疎になった。また同時に、筋周膜シートの崩壊が大きく進行し、特有の波うち構造の消失や構成コラーゲン細線維の消失によるシートの断片化が観察された。
    これらのことから、筋肉内コラーゲン線維立体構造は死後硬直に伴って脆弱化することが示された。なおこの研究成果の一部を、1994年10月の日本畜産学会大会で発表した。
