摘要：

采用碱性蛋白酶Alcalase和复合蛋白酶Protamex分步对膨化的玉米蛋白粉进行酶解改性，应用动物实验的方法研究玉米蛋白酶解物的解酒作用。结果表明：玉米蛋白酶解物中分子质量小于1 000 u的组分占87.76%，含有较高比例的谷氨酸、亮氨酸和丙氨酸；与酒精模型组相比，双酶酶解得到的玉米蛋白酶解物可使小鼠血液中乙醇含量降低59.43%；在一定时间范围内，玉米蛋白酶解物可以提高小鼠胃中乙醇脱氢酶和肝脏中超氧化物歧化酶活性，降低肝脏中丙二醛含量，增加谷胱甘肽含量。

Abstract:

The enzymatic hydrolysate of extruded corn gluten produced by sequential hydrolysis with Alcalase and Protamex
was evaluated for its anti-alcoholism effect in mice. The results showed that the hydrolysate contained 87.76% peptides which
molecular weight is less than 1 000 u, and was richer in glutamic acid, leucine and alanine than corn gluten. Gavage administration of
the enzymatic hydrolysate resulted in a 59.43% reduction in blood alcohol concentrations in mice when compared with the model group.
Moreover, this hydrolysate increased alcohol dehydrogenase (ADH) activity in the stomach of mice, and enhanced superoxide dismutase
(SOD) activity and glutataione (GSH) content but reduced malondialdehyde (MDA) content in the liver within a certain time range.

Key words: corn protein hydrolysate, anti-alcoholism effects, sequential two-enzyme hydrolysis
