Problems solved by technology

[0002] At present, corn, wheat, sweet potato, cassava and other raw materials are generally used to produce crystalline glucose. The technology of using rice as raw material is not mature enough, but because the starch granules contained in rice are smaller than corn, wheat, sweet potato, cassava, etc., about 2- 10um, only larger than oats

Embodiment

[0020] Embodiment: take section (fine) rice as raw material

[0021] Section 1.1 (fine) rice cleaning: Use the bran and rice separation sieve to sift out the bran powder and rice husk, and then use the stone remover to remove other impurities.

[0022] 1.2 Washing: The knot (fine) rice is repeatedly washed with tap water and sent to the soaking tank.

[0023] 1.3 Soaking: adjust the PH value to 10 with soda ash for soaking the knotted (fine) rice to ensure that the soluble protein and fat substances on the surface of the knotted (fine) rice are fully washed to help soften the knotted (fine) rice and inhibit the fermentation of lactic acid bacteria; when the temperature is high Soak for 2 hours, soak for 4 hours when the temperature is low, rinse the rice once with clear water and drain the soaking water before refining.

[0024] 1.4 Refining: Use a grinding wheel to refine the pulp, with a fineness of 60 mesh, no obvious particles by hand, and coarse grains for grinding.

Abstract

The invention relates to a method for preparing crystalline dextrose by rice; rice is used as raw materials and the crystalline dextrose is obtained by carrying out the steps of soaking and jordaning, size mixing, liquefying slag removal, saccharification, a primary neutralization and filtration, a secondary neutralization and filtration, ion exchanging, concentration and refining, crystallization and drying; the method overcomes the defect that pasting of starch granule is not easily realized due to the large size thereof, when corn, wheat, sweet potato, cassava and the like are used as raw materials; the crystalline dextrose prepared by the method of the invention features easy digestive absorption, low anaphylaxis, low fat, no cholesterol and high biological potency and enjoys unparallel advantages compared with other starch glucose; the steps such as high-temperature liquefying, three-time decoloring and hybridization refining, high temperature sterilizing by a crystallizer and aseptic packaging of finished products ensure product quality and food security.

Description

technical field [0001] The invention relates to a process for producing crystalline glucose, in particular to a method for producing crystalline glucose from rice. Background technique [0002] At present, corn, wheat, sweet potato, cassava and other raw materials are generally used to produce crystalline glucose. The technology of using rice as raw material is not mature enough, but because the starch granules contained in rice are smaller than corn, wheat, sweet potato, cassava, etc., about 2- 10um, only larger than oats. And the size of starch granules is a factor that determines the gelatinization speed, and the small granule is easy to gelatinize, and the large granule is not easy to gelatinize, so there is an urgent need for a mature method for producing crystallized glucose with rice as raw material. Contents of the invention [0003] For above-mentioned deficiency of similar technology, the purpose of the present invention is to provide a kind of method with rice ...
