| Abstract: | Process conditions of hydrolyzed wheat starch are studied.On the basis of these,hydrolyzed octenyl succinic anhydride(OSA) modified wheat starch is prepared using the orthogonal test.The results indicate that the optimum hydrolysis conditions for wheat starch are found as follows: reaction temperature 45 ℃,hydrochloric at 4%,reaction period 18 h.The suitable parameters for the preparation of hydrolyzed OSA modified wheat starch are as follows:reaction period 4 h,reaction temperature 34 ℃,pH of reaction system 8.0,concentration of starch slurry 37%(in proportion to water),amount of OSA 3.0%(in proportion to starch).The degree of substitution is 0.019 4. |
