豆渣制取高活性膳食纤维的研究

Study on Producing High Active Dietary from Soybean Residue

依据正交设计法,采用酸解、碱解和酶解3种方法对膳食纤维进行了改性研究。结果表明,酸、碱处理虽然都可以不同程度提高SDF的得率,但处理后的纤维颜色变深,持水力和膨胀力都有所下降,而酶法为一种理想方法。

Methods of producing high active dietary fiber by acid, alkali and enzymolysis treatment were studied by orthogonal design method. The results showed that yield of soluble dietary fiber were raised by all treatment, but the color was dark, the expansion capacity and water holding capacity fell in acid and alkali treatment. Enzymolysis treatment was a ideal method.
