摘要: 本文采用水煮、干热、微波及挤压四种灭酶方法对燕麦麸皮的灭酶效果进行研究,实验以燕麦麸皮中脂肪酶失活率和可溶性膳食纤维提取率为主要指标,以不溶性膳食纤维提取率为参考指标。结果表明:挤压灭酶法效果优于其他三种方法,在挤压温度为130℃-105℃-90℃,进料速度为300r/min,螺杆转速为400r/min时,燕麦麸的脂肪酶完全失活,可溶性膳食纤维提取率达到9.444%,不溶性膳食纤维提取率达到7.980%。

Abstract: Lipase inactivation of oat bran was studied by boiling,dry-heating,microwave heating and extruding in this paper. The results showed that extruding could greatly inactivate the lipase and even make it lose activity completely.The extract rate of soluble dietary fiber is 9.444%,and the extract rate insoluble dietary fiber is 7.980%,when the oat bran is extruded at 130℃105℃-90℃,feed-speed 300r/min and screw-speed 400r/min.

Key words: oat bran, lipase activity, soluble dietary fiber
