Description
Technical field
The present invention relates to biological activity protein preparation fields, and in particular to it is living that a kind of mixed bacteria solid state fermentation prepares rice bran
The method of property peptide.
Background technique
Essential amino acid is complete in rice bran protein, and biological value is higher, and amino acid forms the recommendation mould closer to FAO/WHO
Formula, efficiency ratio are 2.0~2.5.Rice bran protein is mainly substantially pressed by albumin, globulin, glutelin and alcohol soluble protein
37: 36: 22: 5 mass ratio is constituted, and wherein soluble protein accounts for about 70%, protein content, using sexual function (such as cream
The property changed, dissolubility, stability etc.) it is similar to soybean protein isolate.In addition, rice bran protein matter biggest advantage is low allergy
Property, it is the protein that anaphylaxis is minimum in known cereal.So there is high bioactivity using enzymatic hydrolysis rice bran protein matter production
Rice bran active peptide has a vast market foreground that (Fan Jinjuan waits the anti-aging effects of Rice Bran Antioxidant Peptide, Food Science
.2010,31 (23): 40-43).
Currently, the preparation method of active peptide mainly has separation and Extraction method, enzyme process, chemical synthesis, genetic recombination both at home and abroad
Method etc..Wherein enzyme process direct hydrolysis albumen can improve the physics and chemistry and functionality of protein under the premise of not reducing nutritive value
Matter, production active peptide safety is high, in widespread attention.It may be in the prevalence of function inside nutrient protein polypeptide chain
Area selects these polypeptides of protease hydrolytic appropriate, it is possible to be released, to prepare various Functional Polypeptides.Rice bran is living
The technology of preparing of property peptide is mainly for the purpose of anti-oxidant.Lee's Zhe (2012) prepares activity using alkali protease enzymatic hydrolysis rice bran protein
Peptide its to be up to 68.7% (Lee's Zhe, the preparation of Zhai Aihua rice bran protein anti-oxidation peptide and preliminary of the clearance rate of DPPH free radical
Separate Heilongjiang Bayi Agricultural Reclamation University journal, 2012,24 (3): 56-59.).Jia Jun is equal by force to be prepared using neutral protease enzymolysis
The anti-oxidant hybrid peptide of rice out, the ability of removing DPPH can reach 74.8%, and (Jia Junqiang waits ultrasound to pre-process rice protein
Prepare anti-oxidation peptide Journal of Agricultural Engineering, 2008,24 (8): 288-293).The Chinese invention patent of CN 101434980B is announced
A kind of method preparing rice bran short peptide, the invention obtain rice bran short peptide by addition composite protease hydrolysis protein;CN
The Chinese invention patent application of 10208011A discloses a kind of technology of preparing of Rice Bran Antioxidant Peptide, prepares rice bran using alkaline process
Albumen recycles compound protease enzymatic hydrolysis to obtain the rice bran protein peptide with antioxidant activity;The Chinese invention of CN10174818A
A kind of preparation method of Rice Bran Antioxidant Peptide of patent application publication, wherein using basic protein enzymatic isolation method.
As described above, " alkali soluble acid is heavy " is often utilized to prepare rice bran protein matter at present, not only lipidated protein is low, and easily generated
Noxious material, while can bring a large amount of salt ions into keeps product astringent taste excessively high;In the preparation process of active peptide, 2-3 kind enzyme is utilized
Rice bran protein is directly digested, is difficult to isolated disulfide bond and surface hydrophobicity more by force containing a large amount of polymerizations since rice bran protein is intermolecular
Acidic amino acid residue, water-soluble poor, not only purity and yield are low for the active peptide of preparation, also affect its biological activity;And
And it is directly relatively high using enzyme price, enzymolysis product largely all also needs to carry out debitterized technique there is bitter taste.In recent years
Come, though also attempting to carry out solid state fermentation to rice bran using microorganism, since its producing enzyme type and ability are limited, makes the anti-of product
Oxidability it is lower (the Deng Wenhui anti-oxidant Fermentation Conditions food of probiotics solid state fermentation black rice chaff and fermentation science and technology,
2013,49 (2): 50-54)).The above problem constrains the development and application of rice bran Functional Polypeptides, it is difficult to large-scale production.
Summary of the invention
The present invention provides a kind of methods for preparing rice bran active peptide using Mixed Microbes solid state fermentation, directly with fresh rice bran
For raw material, Shenyang (is purchased from using food-grade microorganisms aspergillus niger AS3.410, AS3.350, AS3.365 and aspergillus oryzae AS3.910
Yi Ang Bioisystech Co., Ltd, city).
