Abstract

The invention discloses an industrial production method of rice protein hydrolysate for feed, and belongs to the technical field of feed additive production. The industrial production method of the rice protein hydrolysate for the feed comprises the steps that (1) the method of synergism of various enzymes and multi-step joint processing is adopted, the solid/liquid weight ratio between rice protein powder and water is 1:2-10, and alkaline proteinase is added to carry out dissolution; (2) a complex enzyme preparation which is formed by the alkaline proteinase, neutral proteinase, papain and flavourzyme in a compound mode is added to carry out hydrolysis, and the working procedures such as enzyme deactivation, filtration, decolorization and spray drying are carried out to obtain a rice protein hydrolysate product for the feed. Compared with the traditional method, the hydrolysis conditions are moderate, hygiene and safety are achieved, the situation that original amino-acid composition nutrients are not damaged is ensured, the hydrolysate is low in salinity and mellow in taste, and the yield is high and can reach 98%. According to application tests of adding the rice protein hydrolysate to feed such as feed of suckling pigs, feed of chicks, feed of calves and feed of aquaculture, the rice protein hydrolysate for the feed has the advantages of increasing the daily food-intake amount, reducing the diarrhea rate, improving immunity, reducing weaning stress, and improving growth performance.

Description

technical field [0001] The invention relates to an industrialized production method of rice hydrolyzed protein for feed, which relates to the field of comprehensive development and application of plant protein and the technical field of feed additive production. Background technique [0002] my country's annual rice output is nearly 200 billion kilograms, accounting for about 35% of the world's total output, ranking first in the world. Among them, the output of early rice accounts for about 1 / 4 of the total rice output. At present, the national grain supply and demand are basically balanced, and the total amount of rice is abundant. Early rice and old rice with relatively poor quality were treated coldly, and the inventory was full and could not be sold, resulting in a serious waste of food resources and huge economic losses. Developing high value-added by-products and strengthening the comprehensive utilization of raw materials are effective ways to reduce losses. [000...
