Octenyl succinic anhydride modification of non-crystal granular corn starch
摘要
Abstract
The octenyl succinic anhydride modification was optimized and compared with that of the native corn starch based on decrystallization processing of corn starch. The results showed that the optimum reaction conditions of native corn starch are temperature of 35℃, reaction time of 3 h, pH of 8. 5, starch slurry concentration of 0. 25 g/mL, and OSA amount of 3% (mass percentage of dry starch). The substitution degree of the product is 0. 016 1, and the reaction efficiency is 67. 47%. The optimum reaction conditions of non-crystal granular starch are temperature of 40℃ , reaction time of 3 h, pH of 8. 0, the starch slurry concentration of 0. 25 g/mL, and the OSA amount of 3% (mass percentage of dry starch). The substitution degree of the product is 0.020 5, and the reaction efficiency is up to 85. 94%. Both the reaction efficiency and substitution degree of the esterification product of non-crystal granular corn starch are higher than that of the native corn starch.关键词
