Problems solved by technology

[0002] Generally, organic solvents are used as the medium for the production of modified starch with a high degree of substitution, and the product is easy to smell and the cost is high.
The traditional process of producing modified starch with water as the medium is unstable due to the pH value control, the product substitution degree is low, and the cost is also low, but the addition amount is large when the product is applied

Abstract

The invention discloses a simulated reaction method for producing modified rice starch with high degree of substitution by a wet method. The method comprises the following procedures: taking rice starch as a raw material, preparing the starch into starch milk and respectively adding the starch milk to a simulated reactor and a big reaction kettle proportionally; controlling the temperature and reaction time by the big reaction kettle according to instant feedback data of the simulated reactor, and adding a reaction reagent and pH regulating reagent according to feedback instructions. The method is characterized by instantly instructing the big reaction kettle to add according to the given adding amount and adding speed of the pH regulating reagent after computer processing of instant reaction parameters obtained by the simulated reactor, effectively controlling pH value of the reaction system so as to enhance the degree of substitution. The method has the advantages of reducing production cost, helping expand application of the modified rice starch to various fields, enhance grades of food, cosmetics, medicines and textile products, and reduce product cost.

Description

Technical field: [0001] The invention relates to a wet method for producing modified rice starch with high substitution degree. Background technique: [0002] Generally, organic solvents are used as the medium for the production of modified starch with a high degree of substitution, and the product is easy to smell and the cost is high. The traditional process of producing modified starch with water as the medium is unstable due to the unstable pH value control, low product substitution degree and low cost, but the addition amount is large when the product is applied. Invention content: [0003] The purpose of the present invention is to provide a kind of simulated reaction method that can accurately control the pH value of reaction system, increase the degree of substitution and produce modified rice starch with high degree of substitution. [0004] Technical solution of the present invention is: [0005] A simulated reaction method for producing denatured rice starch w...
