摘要: 采用酶重量法和苯酚硫酸法分别测定车前子可溶性膳食纤维粉中可溶性膳食纤维的含量。结果表明:酶重量法测得车前子可溶性膳食纤维粉中可溶性膳食纤维的含量为87.06%;苯酚硫酸法测得结果为88.54%,且苯酚硫酸法方法学研究结果良好。因此,苯酚硫酸法可以在一定程度上替代酶重量法进行车前子可溶性膳食纤维的测定。

Abstract: The content of soluble dietary fiber (SDF) in SDF powder of Plantago asiatica L. seeds was determined by enzymatic- weight method and phenol-sulfuric acid method respectively. Results showed that the content of SDF in the sample is 87.07% by enzymatic-weight method, and it is 88.54% by phenol-sulfuric acid method. The result of methodological study of phenol- sulfuric acid method is satisfactory. So phenol-sulfuric acid method can replace enzymatic-weight method for the determination of SDF in Plantago asiatica L. seeds.

Key words: Plantago asiatica L., soluble dietary fiber, enzymatic-weight method, phenol-sulfuric acid method
