Embodiment Construction

[0011] Take 1 ton of shrimp head to remove the shrimp skin, crush it into 60 meshes, and then carry out conventional sterilization treatment to obtain about 400 kilograms of raw materials for actual use. The raw materials, water and mixed enzyme are fully mixed in a ratio of 100:20:0.03 by weight Uniform, and control the temperature at 50-70°C for 40-50 hours of enzymolysis, then naturally cool to room temperature (not lower than 20°C), and obtain about 400 kg of a thick product after enzymolysis, and then add cornstarch 200 kg, placed in a dryer with a power of 300kw for about 6 to 8 hours of drying treatment, if the humidity is less than 30%, the drying treatment is qualified, and about 300 kg of dry matter is obtained, and then crushed at 60 to 80 mesh Crushing is carried out on the machine, and packaging is carried out after crushing. The mixed enzyme is a compound enzyme based on protease and acid cellulase, wherein the ratio of protease to acid cellulase is 70%: 30%, the...

Abstract

Production of astapeptide protein is carried out by taking fresh shrimp head as raw material, crushing, sterilizing, adding into mixed enzyme and water, zymolysis reacting at constant temperature, adding into starch, drying and crushing. The macromolecular protein can be degraded into polypeptide with protein molecular weight<5000 dalton as ideal protein source. It can improve digestion absorptive rate of animal, decrease energy consumption and convert common protein into functional protein source. It can promote animal immune disease resistance and enhance minerals absorption.

Description

technical field [0001] The invention relates to the technical field of preparation methods of feed protein sources, in particular to a preparation method of shrimp peptide protein powder. Background technique [0002] Shrimp head is the leftovers in the production process of aquatic products processing plants. It is an important source of protein-rich animal protein with a wide range of sources and abundant resources. At present, most of the processing of shrimp heads is directly used for feed processing after crushing them. The untreated shrimp head powder has low digestion and absorption rate in animals. In addition, there is no report on extracting shrimp peptide protein from shrimp head. Contents of the invention [0003] The purpose of the present invention is to address the shortcomings of the above-mentioned prior art, and provide a shrimp head as raw material, advanced technology, low production cost, low environmental pollution, high absorption rate, high small ...
