Problems solved by technology

[0003] F42 contains 42% fructose. During the production and processing of existing fructose, enzymes need to be added twice during the liquefaction process. After the enzymes are added, the injector is used for injection. The temperature and pressure are too high during injection, which is easy to It causes damage to the enzyme and causes a certain waste. At the same time, due to the presence of cell walls in rice flour, the release of intracellular sugar is greatly hindered, so that the extraction rate of polysaccharides in rice is not high. Therefore, we propose a F42 fructose processing craft

Abstract

The invention provides an F42 fructose processing technology and relates to the field of fructose. The F42 fructose processing technology comprises steps as follows: S1, rice grinding; S2, blending toobtain starch milk; S3, liquidation: liquifying enzyme is added to the starch milk for a reaction; S4, saccharification; S5, ultrasonic treatment; S6, filtration; S7, discoloration; S8, ion exchange;S9, isomerization; S10, secondary ion exchange; and S11, evaporation and concentration to obtain a fructose finished product. Little enzyme is added for the first time before high-temperature and high-pressure spraying, spraying is performed after the sufficient reaction, the enzyme is added again before entering a laminar flow tank, and the reaction is performed again, so that the enzyme is utilized sufficiently; ultrasonic treatment is performed again after the starch milk is subjected to enzymolysis, release of sugar in cells is enhanced, the extraction rate of polysaccharide in the starchmilk is increased, the whole process is simple in structure, damage to the enzyme is reduced, the extraction rate of polysaccharide is greatly increased, cost is saved to a certain extent, and the practicability is high.

Description

technical field [0001] The invention relates to the field of fructose, in particular to an F42 fructose processing technology. Background technique [0002] Containing 6 carbon atoms in fructose, it is also a monosaccharide, which is an isomer of glucose. It exists in a large amount in fruit juice and honey in a free state. Fructose can also combine with glucose to form sucrose. Pure fructose is a colorless crystal with a melting point of 103-105°C. It is not easy to crystallize and is usually a viscous liquid that is easily soluble in water, ethanol and ether. [0003] F42 contains 42% fructose. During the production and processing of existing fructose, enzymes need to be added twice during the liquefaction process. After adding enzymes, use an injector to spray. When spraying, the temperature and pressure are too high, which is easy It causes damage to the enzyme and causes a certain waste. At the same time, due to the presence of cell walls in rice flour, the release o...
