(2) background technology:
Livestock products security incidents such as the two mouthfuls of abusive tongue English pollution that takes place in succession both at home and abroad latter stage in last century, rabid ox disease, beta-stimulants poisoning have caused various circles of society's showing great attention to animal product and feed safety problem.At present, in order to improve foodsafety, utilize the plant protein resource of high-quality to substitute traditional animal protein feed in the world, to guarantee livestock products safety.
Dregs of beans is one of the most important vegetable protein of livestock and poultry source, and its crude protein content is up to 43-48%, and is made up of the amino acid than balance, and lysine content is up to 2.5-2.8%.But there is multiple ANFs in the dregs of beans, wherein mainly contain thermally labile ANFs such as trypsin inhibitor, soybean haemoglutinin, goitrin, urase and the antivitamin factor, and thermally-stabilised class ANFs such as phytic acid, oligosaccharide and glycinin, these factors have greatly influenced the feeding value and the application in children's livestock and poultry diet in age thereof of dregs of beans, and cause problems such as children's animal and bird intestines in age allergy and diarrhoea easily.In the dregs of beans production process, adopt heat treated mode that these ANFs are handled usually, then partly lose anti-oxidant action for the thermally labile ANFs, but still some is residual, however thermally-stabilised class ANFs still be present in the dregs of beans, can't eliminate.And, usually the dregs of beans production technology that adopts both at home and abroad need be handled the dregs of beans sterilization at present, the dry loss is bigger in Fa Jiao the process simultaneously, and in the process of aerobic fermentation, may have the reproductive processes of some harmful bacterium, the shared ratio of the peptide matters that produces in the sweat is on the low side in addition.Therefore, invent a kind of anaerobic fermentation soya bean watse and production method thereof, significant to the nutritive value that improves dregs of beans, also be the developing direction of dregs of beans product deep processing from now on.
(3) summary of the invention:
Goal of the invention of the present invention is to invent a kind of anaerobic fermentation soya bean watse and production method thereof, the particularly a kind of production method that can eliminate thermally-stabilised class ANFs such as soybean antigen in the dregs of beans, this method can solve ANFs content height in the existing market circulation dregs of beans protein raw material, causes problems such as children's animal and bird intestines in age allergy and diarrhoea easily.
Technical scheme of the present invention: a kind of anaerobic fermentation soya bean watse, the survival rate that it is characterized in that thermally labile ANFs and thermally-stabilised class ANFs in the anaerobic fermentation soya bean watse is less than 3-5%; Molecular weight is higher than 90% at the little peptide of 19-48KD in the anaerobic fermentation soya bean watse protein.
