| 摘 要： | 采用胰蛋白酶、碱性蛋白酶、中性蛋白酶水解花生蛋白,研究了水解过程中水解度的变化,并对水解产物的ACE抑制活性进行了探讨。得出三种酶对花生蛋白的水解作用:碱性蛋白酶>胰蛋白酶>中性蛋白酶。碱性蛋白酶水解产物ACE抑制活性明显高于胰蛋白酶和中性蛋白酶,水解产物的ACE抑制活性高达89.73%,中性蛋白酶水解产物ACE抑制率仅为27.24%。

| Abstract: | Peanut protein hydrolysates were prepared by enzymatic hydrolysis with Trypsin,Alcalase,and Neutrase respectively.The degree of hydrolysis(DH)and the inhibitory activity to angiotensin I-converting enzyme(ACE)of the hydrolysates were investigated.Results indicate that the inhibitory activity to ACE ranges as Alcalase > Trypsin > Neutrase;the peanut protein hydrolysates produced with Alcalase gives ACE inhibition index of 89.73%,and the inhibition index of that with Neutrase is only 27.24%. |
