Biochemical changes of natural actomyosin from fresh pale, soft, exudative (PSE) and normal pork were studied, and the effects of different storage temperatures and different incubation temperature and times on sample superprecipitation, total sulfhydryl (-SH) content, and ATP (adenosine triphosphate) sensitivity were investigated. The results demonstrated that ATPase activity and thermal stability of PSE actomyosin were lower than those of normal pork; and that PSE actomyosin had higher -SH content than that of normal pork at all incubation temperatures and times tested. 相似文献

INTRODUCTION The meat industry is facing consumer demandsfor high, predictable, and consistent meat quality.One of the major problems is the change in exuda-tion, colour, and firmness that characterize meatquality. High incidence of pale, soft and exudative(PSE) pork cause poor technological quality, driploss, and shrinkage during storage as well as unat-tractive visual appearance for consumers. PSE porkalso causes an economic impact on the industrybecause of product dehydration d… 相似文献
