Study on the Preparation Technology of Semen Litchi Starch Phosphoester
The semen litchi starch phosphoester was prepared by semi-dry method with sodium tripolyphosphate, and its degree of substitution was measured after the influence of different factors including pH value, reaction time, temperature, and esterifying agent. The following optimized conditions was obtained through orthogonal experiments: the reaction time was 1.5h, temperature was 150℃, and the esterifying agent was 6% of dry starch, and the DS of fi-nal products was about 0. 0163.
