The condtions optimization of α-amylase hydrolyzing rice
Abstract：In this article we use amylase to hydrolyze the main component of infant cereal- starch in part,to solves defections in the traditional technology of cereal production and makes cereal- starch taste more delicate, more conducive to the baby's digestion and absorption.Experiment with soluble starch as raw material, obtainα-amylase activity through iodine - starch qualitative method.And then to the rice flour as raw material,makes reducing sugar, DE as index, quantitative study a certain extent DE value,the amount of enzyme dosage and in certain conditions the best conditions and under the different temperature condition , the different killing enzyme time . Finally, establish in vitro digestion and absorption simulation model for testing and improving digestion and absorption of the product.
