| Abstract: | The content and the proportion of amylose and amylopectin are important indexes of sorghum. Sorghum is major raw materials in brewing industry. Therefore,it is important to establish a rapid,simple and accurate method of determining the content and proportion of amylose and amy-lopectin in sorghum. An assaying method of amylose and amylopectin using dual wavelength was established according to GB7648-87 in this paper. The results showed that the new method had a good repetition and could be applied for anal... |
