Embodiment 1

[0030] (1) Raw rice processing: Take the raw rice, put it in a soaking tank, add water at 60°C from the water storage tank, and soak for a certain period of time to make the rice grains initially expand; after soaking the rice, remove stones, iron, and grind it Starch milk, so that the concentration of starch milk is 31%;

[0031] (2) Add 6 units / g raw material α-amylase to starch milk, add Na 2 CO 3 The solution adjusts the pH of the starch milk to 5.9-6.0, and uses two high-pressure jets to liquefy. The jet temperature is 105-107°C once and 125-127°C twice, and the pressure is 0.2-0.4mPa. After the second liquefaction, add 2 Unit / gram of raw material α-amylase; then, at a high temperature of 95-100 ℃, and then through the liquefaction maintenance tank, α-amylase plays a biochemical role, cutting off the α-1,4 bonds of the starch chain, and hydrolyzing the starch into Liquefied liquid of dextrin, oligosaccharide, trisaccharide, maltose and a small amount of glucose;

Abstract

The invention discloses a starch syrup production method comprising the steps of: raw material rice processing, liquefaction, slag removing, saccharification, decolorizing, pressure filtering, ion exchange, pH regulation, condensation, and packaging. The method provided by the invention has the advantages such as fully automated operation, stable process control, high product quality, high product yield, low raw and auxiliary material consumption, low environment pollution, and the like. The technology is internationally advanced.

Description

technical field [0001] The invention mainly relates to a production method of syrup, in particular to a production method of starch syrup. 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] ①Acid hydrolysis. There ...
