Problems solved by technology

The production capacity of small peptides for feed by protein hydrolysis is high, but the cost of raw materials is high, the cost performance of the product is low, and the relative cost is high; although the content of small peptides is relatively high, the bitter taste produced by the high peptide content affects the palatability of the product. It has a greater impact on animal feed intake, and its super hygroscopicity, higher cost and palatability affect its practicality, usage amount and range of use
The detection method of product small peptide is commonly used by HPLC or MS method, which requires expensive chromatograph and is difficult to be used in routine qualitative and quantitative analysis
Other chromogenic methods have large fluctuations in the determination of peptide content, and are not suitable for the determination of low-level small peptide content

Abstract

The present invention is one kind of small peptide feed additive with rich small peptide and probiotics matter and no anti-nutrilite. The small peptide feed additive is prepared with soybean residue, wheat bran, corn protein powder, corn starch, alcohol dreg, tropina powder, waste molasses and / or starch, and through inoculating probiotics seed and solid fermentation to eliminate anti-nutrilite and generate small peptide, lactic acid and other probiotics matters. It has total small peptide content not less than 15.0 wt%, amino nitrogen content 0.5-1.0 %, total nitrogen content not less than 8.0 %, lactic acid content not less than 3.0 %, water not more than 12.0 % and molecular weight smaller than 20,000 Dalton. The small peptide feed additive can raise the speed of synthesizing protein in animal body, appetize, raise body's immunity, promote the absorption of animal body on mineral elements, regulate physiological activity and improve nutritious condition.

Description

technical field [0001] The invention relates to a small peptide additive for feed and a preparation method thereof, more specifically to a non-antinutritional protein obtained directly from compound probiotic strains through solid-state fermentation of microorganisms without steaming and sterilizing protein raw materials and auxiliary materials. Factors, feed small peptide additives rich in small peptides and prebiotics, and preparation methods thereof. Background technique [0002] Peptide is a general term for a class of substances in which amino acids are connected by peptide bonds and have a certain degree of polymerization. The degree of polymerization and molecular weight are between proteins and amino acids. According to their different functions, they can be divided into two categories: functional peptides and nutritional peptides. Functional peptides are biologically active peptides, which can participate in regulating certain physiological activities of animals or...
