Abstract: Broken rice starch was modified with octenyl succinic anhydride in aqueous slurry system. The modification process was optimized by one-factor-at-a-time and orthogonal array design methods to achieve maximum degree of substitution (DS). The results showed that the optimal process conditions were found to be: starch slurry concentration 30%, pH 8.5, reaction time 5 h, and reaction temperature 35 ℃. Under the optimal conditions, the degree of substitution was 0.01445.

Key words: broken rice starch, octenyl succinic anhydride, degree of substitution
