摘要
主要研究了粉末活性炭对小麦胚芽酶解液的脱色条件。以脱色率和氮保留率为指标,考察了粉末活性炭的脱色效果,同时测定了脱色对小麦胚芽酶解液抗氧化活性的影响。结果表明,粉末活性炭的最佳脱色条件为:活性炭用量2%,脱色时间30 m in,脱色温度50℃。在此条件下酶解液脱色率为83.9%,氮保留率为60.6%。活性炭脱色会在一定程度上削弱酶解液的抗氧化活性。
Powdered activated carbon was adopted to decolorize antioxidative peptides from wheat germ hydrolysate. Effects of decolorization were studied by determining the decolorizing rate and the reserved rate of nitrogen. Meanwhile, the effects of decolorization on the antioxidative activities of wheat germ hydrolysate were studied. The result showed that when the powdered activated carbon concentration was 2% ,decolorization time was 30 min and decolorization temperature was 50 ℃, the decolorizing rate was 83.9% and the reserved rate of nitrogen was 60.6%. The decolorization procedure weakened the antioxidative activity of wheat germ hydrolysatcs to some extent.
