菠萝蛋白酶限制性酶解大豆7S球蛋白产物在猪肉肠中的应用

摘要

Soybean conglycinin hydrolysates with different hydrolysis degree (DH) were obtained through limited proteolysis by Bromelain. The effects of different DH and different dosage of conglycinin hydrolysates on the texture and yield of pork sausage were compared. Through orthogonal test, the proper technology parameters were obtained as follows:DH of conglycinin 6% and dosage 1.5%.%采用菠萝蛋白酶对大豆7S球蛋白进行限制性水解,将不同水解度的7S球蛋白酶解产物添加到猪肉肠中进行应用研究.以质构特性、肉肠得率为评价指标,比较了不同水解度和添加量的7S球蛋白酶解产物对猪肉肠品质的影响.采用正交试验,确定了猪肉肠专用蛋白的最佳工艺参数:7S球蛋白水解度为6％,添加量为1.5％.
