Preparation and Properties of Glutinous Rice Starch Hydrogels

WANG Mao-guang;Linyi University;  
The research aimed to optimize condition of glutinous rice starch hydrogels and evaluate properties of it. With glutinous rice starch as raw materials,4-dimethylamino pyridine as catalyst and succinic anhydride for starch hydrogels,the preparation of rice starch hydrogels for optimum conditions was determined:the hydroxyl molar ratio of succinic anhydride and the native starch is 10∶1,the hydroxyl molar ratio of catalyst and the native starch is 1.05∶1. The infrared structural analysis and DSC result indicated that the butane diacid group had been induced in the starch molecule. The starch hydrogels was significantly improved in the water-absorption. Compared with the native starch,hydrogels starch significantly enhanced transmittance and freeze-thaw stability.
