小麦和酿酒大麦发芽过程中主要酶活的比较研究

Comparison Research on Main Enzymes Activity during Wheat Germination and Barley Germination

对小麦、大麦发芽过程主要酶(α-淀粉酶、β-淀粉酶、植酸酶、过氧化物酶和多酚氧化酶)活力的动态变化进行比较研究。结果表明,在发芽过程中,小麦和大麦中几种酶的酶活力变化具有较高的一致性,即发芽前4d酶活不断增加,随后出现下降趋势。

The dynamic change of the activity of main enzymes including α-amylase, β-amylase, phytase, peroxidase and polyphenol oxidase during the germination of wheat and barley were studied and compared.The results showed during the germination of whatever wheat and barley, the activity change of main enzymes presented high consistency （enzyme activity kept increasing 4 d before the germination and then declined subsequently）.
