Production process of starch syrup

Abstract

The invention discloses a production process of starch syrup. The production process comprises the following steps: 1) treating raw rice; 2) liquefying; 3) removing dreg; 4) saccharifying; 5) de-coloring and filtering with pressure; 6) carrying out ion exchange; 7) regulating pH (Potential of Hydrogen); 8) concentrating and evaporating; 9) packaging a finished product. According to the production process of the starch syrup, disclosed by the invention, a process of carrying out two times of spraying, carrying out two times of enzymes adding and liquefying, carrying out countercurrent carbon conveying and de-coloring for two times, circularly protecting and carrying out ion exchange is adopted; the consumption amount of resin, acid and alkali is low and the investment is less; meanwhile, a three-effect falling film is used for concentrating in vacuum and the steam consumption amount and the water consumption amount are low; different starch syrup (including liquid glucose, liquid dextrin, beer syrup and isomaltooligosaccharide) can be produced by properly adjusting a process route and technological conditions and the comprehensive energy consumption of per tonnage of sugar is low.

Description

technical field [0001] The invention relates to a starch syrup production process. Background technique [0002] There are five types of starch sugar production technology routes: acid method, enzyme method, acid enzyme method, double enzyme method, solid phase isomerase (continuous stirring method, enzyme layer filtration method and enzyme column method). Different processes have different sweetness, viscosity, thickening, moisture retention, hygroscopicity, osmotic pressure, color stability, coking, reduction, and fermentability. No matter what kind of process is a complex hydrolysis process. There are three main reactions in the starch hydrolysis process: one is hydrolysis to glucose; the other is hydrolysis to glucose and recombination into complex sugars such as isomaltose; the third is the decomposition of glucose to produce 5-hydrocarbon methyl furfural and pigment substances. [0003] Starch sugar products are obtained by hydrolysis of starch. Therefore, the speed ...

Problems solved by technology

In short, no matter what the liquefaction method is, there are insoluble starch granules, which can form complexes with fats, have a helical structure, are not easy to hydrolyze, and reduce the saccharification rate
