Description
Technical field
The industrialized preparing process of method of rice protein hydrolysate for a kind of feed, relate to comprehensive exploitation application and the technical field of feed additive production of vegetable protein.
Background technology
Nearly 200,000,000,000 kilograms of China's paddy annual production, account for 35% left and right of Gross World Product, occupies first place in the world.Wherein the output of early rice accounts for 1/4 left and right of paddy total output.Current, national grain supply and demand is in a basic balance, and the rice total amount is abundant.Poor rice morning, the old rice of quality is cold-shouldered, and the stock is full, can not sell, and causes the serious waste of grain resource and huge economic loss.The byproduct of exploitation high added value, strengthen raw material is fully utilized, and is the effective way that reduces loss.
Rice protein accounts for 8% left and right of rice gross weight, have high nutrition, hypoallergenic, local flavor gentle, can not cause the peculiar property such as ventosity.Its application is more and more extensive, as be used as, produces rice protein powder, hydrolysed rice albumen, rice modified protein, high added value peptide, biologically active peptide, resistance protein; Can be used as the cub feed addictive, improve the absorption of cub to nutrition, improve premunition.
Method of rice protein hydrolysate as a kind of high-quality without antigen vegetable protein source, the countries such as Europe be widely used in newborn baby pig feedstuff, high-grade aquatic products material, calf for milk powder and feed for pet in.Be characterized in having very high glutamine content (up to 30%), documents and materials show: stress or limit and raise (during weaned piglet) under condition, glutamate is main restrictive factor, the weanling pig artificial synthetic glutamate of feeding, can improve small intestine alimentary canal shape (intestinal villi structure), improve immune response.Although domestic, have producer using this product, this product there is no suitability for industrialized production at home.
Method of rice protein hydrolysate is to take natural vegetable protein through modification, to form as raw material, it is the green safety plant protein products, can overcome the bio-safety problem of plasma protein homology, can avoid again soybean protein to meet with genetically modified trade barrier, not have the restriction in application.Latest research shows, with hydrolysis, wait the biochemical treatment Gluten to make the protein hydrolysate feed piglet is had to very high digestibility, without ANFs, can promote the growth of intestine of young pigs fine hair, obtain higher feed efficiency, the spray-drying plasma protein (2.5%~8%) of alternative costliness.At present, the research of domestic relevant hydrolysis defatted soybean, cotton dregs is more, less about the research report of enzyme modification rice protein.(the Faoming properties of enzymatially hydrolysed wheat gletun such as Drago, Cereal Sci, 2000,32:114-135) adopt the heat treated Gluten of fungal proteinase hydrolyze to find, Gluten solubility increases and increases along with degree of hydrolysis (DH), but foaming characteristic when exceeding certain DH scope by destroyed.Qi Junru etc. (Zhengzhou Engineering College's journal, 04 phase of calendar year 2001,48-51 page) adopt the neutral proteinase hydrolysis rice protein, and have studied the controlled hydrolysis rice protein, and show: controlled hydrolysis has improved the functional characteristic of rice protein greatly.(the grain and feed industries such as Zhao Dongyan, 08 phase in 2003,39-41 pages) improve the functional of rice protein with alkali protease (Alcalase), studied the impact on the rice protein emulsibility of rice protein concentration, enzyme concentration, pH value, heat time heating time and temperature, and, on this basis by orthogonal experiment, explore the optimum condition that alkali protease improves rice protein function.Recording the front rice protein solubility of modification is 7.67%, and under the optimum condition of modification, its solubility is 20.76%, and as can be seen here, the solubility of rice protein is greatly improved after the Alcalase hydrolysis; When the rice protein modification obtains the optimum emulsification effect, its degree of hydrolysis is 3.2%.(the food and fermentation industries such as Huang Jihong, 2004,30 (1): 92-94) to adopting the enzymatic hydrolysis rice protein to produce biological activity protein, carried out pilot study, think that enzymatic hydrolysis is the effective way that improves the rice protein food function, can be by protein-modified to desired functional characteristic.
From above-mentioned report, the correlative study of enzymatic hydrolysis rice protein at present all rests on laboratory stage, does not carry out further scale-up research, also could not realize suitability for industrialized production, and enzyme preparation adopts single composition more.Carrying out the feeding method of rice protein hydrolysate product of industrial-scale production by enzyme modification have not been reported.It is the ideal substitute of animal protein that rice protein generates the rice functional protein through enzyme modification, aspect animal-breeding, has broad application prospects and huge market potential.
Summary of the invention
For meeting the need of market, the object of the invention is to provide a kind of new method that adopts the feeding rice protein of composite protease hydrolysis, and realizes suitability for industrialized production.
For realizing the object of the invention, technical scheme is as follows:
According to the characteristic of rice Gluten and the characteristics of animal nutrition, utilize chemistry and enzyme process to carry out modification to rice protein, start with and inquired into the impact of each factor on the rice protein enzymatic hydrolysis from five factors (solid-to-liquid ratio, pH value, enzyme concentration, temperature and time) of restriction rice protein hydrolysis, obtain process conditions on the orthogonal experiment basis, through pilot scale and suitability for industrialized production test, obtain feeding method of rice protein hydrolysate product.Product is rich in glutamine, and the form mainly with little peptide exists greatly, and molecular weight is less than 2000 daltonian little peptides and accounts for more than 60%, wherein is less than 1000 daltonian little peptides and accounts for more than 50%.
