摘要: 采用离子交换法,研究了海带、马尾藻两种膳食纤维提取过程中功能活化的工艺条件。结果表明,在最佳活化条件下提取的海带和马尾藻膳食纤维的干基含量分别为84.3%和82.7%,钙含量分别为6.21%和5.36%,膨胀力分别为138ml/g和108ml/g,持水力分别为6720%和5320%,两种产品的质量指标都远高于未活化的膳食纤维。通过人体试验,两种膳食纤维都具有良好的通便作用,其中海带膳食纤维的作用稍优于马尾藻膳食纤维,而作用最差的为未活化的马尾藻膳食纤维。

Abstract: The technological conditions of functional activities in extracting two kinds of dietary fibers(DF) from Laminaria japonica and Sargassum were studied by ion-exchanging. The results showed that the contents on dry basis of DF and calcium, expansive capacity and water holding capacity of Laminaria japonica were 84.3%, 6.21%, 138ml/g and 6720% respectively, and those of Sargassum were 82.7%, 5.36%, 108ml/g and 5320% respectively for the two kinds of DFs extracted under the optimum activate conditions. The quantity index of two kinds of products were far higher than unactivated DFs. By testing of human body in take orally,two kinds of DFs had a good laxative effect for constipation patient. The effect of Laminaria japonica DF was a little better than Sargassum DF, but the effect of unactivated Sargassum DF was the worst among all.
