摘要
通过对胃蛋白酶、胃膜素提取联产工艺的试验和考察,得出了胃粘膜消化的优化工艺条件:温度40～45℃, pH2.5～3.0,消化时间4h。减少了丙酮溶剂的用量,缩短了丙酮沉淀胃蛋白酶时间,使胃蛋白酶的收率提高到4.5～5.5％,原酶效价稳定在1:22000左右,胃膜素的收率在1.5％以上。
The optimum conditions of digesting gastric mucosa were 40~45℃,
pH2.5~3.0, and 4h. The total yield of pepsin ranged from 4.5 to 5.5%, its activity
was about 1:22000 yeild of gastric mucin was more than 1.5%.
