Study on Preparation and Properties of High DS Succinate Cornstarch by Semi-dry Process
摘要
Abstract
Preparation of succinate starch with high degree of substitution (DS) by semi-dry process was studied using cornstarch as raw material,succinic anhydride as esterifying agent,and sodium bicarbonate as catalyst. The effects of different parameters on the DS were discussed with the aim to provide a theoretical basis for the industrial production. The results showed that the suitable parameters for the preparation of succinate starch were as follows: amount of succinic anhydride 9% (in proportion to starch, m/m), water content 25% (m/m), amount of NaHCO3 4%(in proportion to starch,m/m),reaction temperature 135 ℃ ,reaction period 2 h. The DS was 0. 163 3 under the suitable parameters. Some changes in the structure of succinate starch with high DS were discovered,a new characteristic absorption peak emerged,the gelatinization temperature was decreased and the peak viscosity was increased.关键词
