摘要
通过对在不同发芽温度和不同发芽时间下培养的芽麦粉中α 淀粉酶活性、降落值、还原糖及非还原糖含量的测定 ,研究了发芽小麦的α 淀粉酶活性、降落值、还原糖及非原糖含量与芽麦的发芽温度和发芽时间的关系。并通过响应面分析法 ,进行中心组合设计 ,得出了它们的二元二次回归方程。并对植酸作为α 淀粉酶抑制剂的抑制效果进行了研究 .通过测定不同植酸添加量下的α 淀粉酶活性及降落值 ,表明植酸对α 淀粉酶的抑制效果十分明显 。
The relationship tetween the acivity of α amylase,descend value,the content of reducing sugar and non reducing sugar in geminant wheat and its germination temperature and time are studied by analyzing the activity of α amylase,descend value,the content of reducing sugar and non reducing sugar in germinant wheat flour which are cultured at different germinant temperature and time.A duality regression equation was obtained by surface response analysis and center combination desigh.The inhibition effect of phytic acid as the inhibitor of α amylase is also studied.The results show that the inhibition effect of phytic acid is obvious,and it is an ideal improver for quality of germinant wheat.
