摘要 通过对真空包装的牛肉施加不同的压力 (10 0 Mpa~ 35 0 Mpa)和不同时间的处理 ,分析测定牛肉中钙激活酶和钙激活酶抑制蛋白活性的变化规律 ,研究了钙激活酶及其抑制蛋白的压力动力学 ,并探讨了高压嫩化牛肉的作用机理。结果表明钙激活酶对压力有一定的耐受性 ,而钙激活酶抑制蛋白对压力较敏感。 High pressures of 100Mpa to 300Mpa were applied to beef post mortem muscle to investigate the effect of high pressure on caplains and caipastatin activity.to study the reactivily dynamics of calpains induced by high pressure treatment and elucidate the mechanism of meat tenderization by pre-rigor pressurization.It was suggested that calpain was more resistant to high-pressure treatment than calpstatin.
