Abstract
The invention relates to a method for producing an active polypeptide rich product by solid state fermentation and application. The method comprises the following steps of: preparing a solid state fermentation culture medium by using bean pulp and bran as raw materials, sterilizing, cooling, inoculating a seed solution of activated aspergillus niger or bacillus subtilis, adding KH2PO4, performing fermentation culture at the temperature of between 28 and 32 DEG C for 60 to 70 hours, heating to the temperature of between 50 and 52 DEG C after fermentation is finished, hydrolyzing, drying the fermentation product till the water content is less than 8 percent, crushing, sieving with a sieve of 80 meshes, and thus obtaining the active polypeptide rich feed product. The soybean active polypeptide product prepared by using the method basically does not contain anti-nutritional factors, has small molecular weight, is easily absorbed, and has a remarkable promoting effect on the production performance of weaned pigs.
Description
Technical field
The invention belongs to food processing technology field, relate to method and application that the active peptides goods are rich in a kind of solid state fermentation production.
Background technology
The dregs of beans crude protein content is abundant; Amino acid is formed rationally, in addition, contains other nutriments and many active materials that can produce biological effect such as fat, carbohydrate, vitamin; Like soyabean oligosaccharides, isoflavones, soybean active peptide etc., be a kind of good plant-derived albumen feed.
Contain multiple ANFs (anti-nutritional factors in the dregs of beans; ANF), like trypsin ihhibitor, urase etc., discover; These ANFs have influenced digestion, the absorption of livestock and poultry to nutritional labeling, influence health and the production performance of animal.This just need handle ANFs, thereby improves the digestibility of dregs of beans, improves nutritive value, and processing method commonly used so far is summarised as: physical method, chemical method and biological method.
Method through microbial fermentation prepares protease, and with this hydrolysis process dregs of beans, the high molecular weight protein in the dregs of beans is hydrolyzed into micromolecular peptide by protease etc., and the utilization rate of protein is improved.Soybean Peptide has good physicochemical property, and boundless application prospect is arranged aspect food and medicine, and fermented bean dregs is at animal health, and is especially respond well aspect the enteric microorganism of regulating young animal, is widely used in herding and feed industry circle.In addition, the microbial fermentation dregs of beans need not heat or add chemical reagent, and the ruined possibility of feed nutrient is little, and application safety is practical.
Soybean Peptide has unique physical and chemical properties and multiple biologically active.Method through microbial fermentation can be removed the multiple ANFs in the dregs of beans effectively, reduces cost, and improves the utilization rate of product, has wide significance in actual production with in using.Yet the preparation of protease receives the influence of envirment factor.As: the 1. influence of pH.The protease kind that culture medium produced of different pH values is different, the optimum pH of the generally close and participation enzymatic reaction of the pH value of the protease that produces.2. the influence of ventilation.The process that deep layer is cultivated; Need to ventilate stir how many influences that how much receive ventilation of the growth of fungal hyphae and yield of enzyme, how much in actual production, will the controlling well of ventilation; To be beneficial on the one hand the growth of thalline, effect that on the other hand can the CKIs enzyme.3. Influence of Temperature.It is different that different microbial fermentation produces the required optimum temperature of enzyme, and it is too high or cross low influence that the growth of thalline, the cycle of producing enzyme all can receive temperature, is unfavorable for the generation of highly active protein enzyme like this.In addition; The composition of fermentation medium and the generation of other metabolites also can have influence on the fermenting and producing of protease, therefore, in the actual production should according to screen fermentation, the hydrolysising condition that the microorganism that obtains gropes to suit; Thereby obtain sufficient protease, further improve the Soybean Peptide conversion ratio.
