Embodiment 1

[0030] Bacillus licheniformis, Bacillus subtilis, Enterococcus faecalis and Saccharomyces cerevisiae used in this example were all purchased from Hubei Lvtiandi Biotechnology Co., Ltd.

[0031] 1) Choose 1 ton of rice protein crushed to 40-60 mesh, add it to the reaction tank, and set aside;

[0032] 2) According to the measured rice protein moisture content, measure water that can make the moisture content of the material to 50% to 60% and add it to the material;

[0033] 3) Weigh a certain amount of sodium hydroxide, dissolve it with a small amount of water, and add a certain amount of sodium hydroxide solution to adjust the pH value of the material to 6.5-7.0 according to the measured pH value of rice protein;

[0034] 4) Weigh the amount of bacteria to be added (see Table 1) and dissolve it in water to prepare the bacteria solution: add the bacteria solution to the material and mix well;

[0035] 5) The mixed material is fermented in an environment of 35-45°C for 3-5 days...

Abstract

The invention discloses a method for producing rice polypeptide by adopting solid state fermentation. The method comprises the following steps: crushing rice protein powder into 40-60 meshes, and regulating the moisture of a rice protein material to 50%-60% and a pH value to 6.5-7.0; adding three or four of bacillus licheniformis, bacillus subtilis, enterococcus faecalis and saccharomyces cerevisiae to the material, uniformly mixing, fermenting at 35-45 DEG C for 3-5 days; after the fermentation is completed, drying and crushing the material, and then packaging if being inspected to be qualified so as to obtain a finished product. The rice polypeptide produced through the method disclosed by the invention has the advantages of good solubility, fast absorption in vivo and high utilization ratio and has the functions of disease prevention, disease treatment and animal physiological function regulation.

Description

technical field [0001] The invention relates to a technique for producing rice polypeptides by using the existing rice protein by a solid-state fermentation method, which belongs to the field of food processing. Background technique [0002] my country is a big rice producing country with abundant rice resources. Rice protein is obtained by using leftovers from rice sugar production in monosodium glutamate factories, citric acid factories and sugar factories. Economic benefits, and the small molecular peptides produced by enzymatic hydrolysis of rice protein also have many biological activities, which provide more supplements for animal husbandry, food industry and human nutrition and health care, and have broad application prospects. The amino acid ratio of rice protein is reasonable and contains the essential amino acids needed by the body. [0003] Rice polypeptide is the fermentation product of rice protein, its amino acid composition is almost the same as that of rice...
