摘要
考察了复合酶制备的花生粕多肽的组分、分子量及抗氧化性能。结果表明:采用复合酶制备花生粕多肽经SephadexG-15凝胶过滤层析得到2个组分;SDS-PAGE电泳法测定花生粕多肽的两个组分的分子量分别为823.5D和1078D;花生粕多肽原液、分子量为823.5D的组分、分子量为1078D的组分均具有一定的抗氧化性能,其中分子量为823.5D组分的抗氧化能力优于分子量为1078D的组分。
The component, molecular weights and antioxidant property of peanut-meal peptides which were prepared by complex enzyme were investigated in this study. The results showed that two components were obtained from the peanut-meal peptides through Sephadex G-15 gel permeation chromatographic separation. The molecular weights of two components were 823.5D and 1078D respectively which were determined by SDS-PAGE electrophoresis, the peanut-meal peptides, and two components all have antioxidant properties, the antioxidative effect of component with molecular weight 823.5D was superior to the component with molecular weight 1078D.
