Abstract:
Taking the chestnut starch as material，the debranching degradation resistant starch was prepared by acid and enzymolysis debranching methodsits.The preparation process of the concentration of starch milk，add the amount of acid pretreatment and hydrolysis time，add the amount of influence and pullulanase hydrolysis time on the yield were studied.Then，to explore the best preparation process and make verification by response surface methodology.The results showed that the optimum process conditions for the preparation of resistant starch chestnut as follow，starch milk concentration was 22.5%，the additive amount of acid was 0.06%，acid treatment time was 136.8 min，enzyme dosage was 13.9 U/g，hydrolysis time was 407 min，resistant starch yield of 18.69%.
