| Abstract: | The real situation is analyzed for amylum gelatinization and its testing equipment. In order to discuss the amylum gelatinization and gelatinizating temperature impact on the boiled water bath, shorting the boiled bath time are proposed in the process of the examination for four kinds of amylum samples. The testing equipmentis studied, which can be widely used to examine the quality of amylum acceleratively and its price very cheap, using monochromatic light source, which wave length is 635 nm, is researched in theory in two ways Dyndall scattering and molecular scattering. |
