摘要
主要研究酶法和碱法两种不同处理对胡麻可溶性膳食纤维(SDF)抗氧化活性的影响。结果表明碱法处理后的样品对ABTS清除能力、DPPH清除能力、还原力显著高于酶法提取的(p 2+的络合能力比碱法提取的SDF强,络合率可达94.93%。这表明,经碱法和酶法处理后的样品中都有一定的抗氧化活性,酶法和碱法处理胡麻渣提取得到的SDF是一种来源丰富、经济前景良好的抗氧化剂资源。
The effects of enzyme and alkali treatment on the antioxidant activity of flax soluble dietary fiber(SDF)are studied in this paper.The results show that the scavenging ability on ABTS and DPPH and reducing power of alkali-treated samples are significantly higher than that of enzyme extraction(p 2+than that extracted by alkali method and the chelating rate can reach 94.93%.These results indicate that the samples treated by alkali method or enzyme method have certain antioxidant activity.SDFs extracted by enzymatic method and alkali method are an antioxidant resource with rich sources and good economic prospect.
