Abstract

The invention provides a recovery method of low-value fish processing by-products. The recovery method comprises the following steps: (1) adding the low-value fish processing by-products into water, performing uniform stirring to obtain a mixed solution, regulating the pH value of the mixed solution to 6-7, adding compound protease into a vacuum environment, performing heating to 40 DEG C, performing enzymolysis for 3-5 hours to obtain enzymatic hydrolysate, heating the enzymatic hydrolysate for enzyme deactivation, performing cooling, cooling filtering to obtain filtrate, and drying the filtrate to obtain zymolyte; and (2) crushing the zymolyte, sieving the crushed zymolyte with a 80-mesh sieve to obtain zymolyte powder, stirring the zymolyte powder, the zymophyte and water until the materials are uniformly mixed to obtain a mixed material, performing sealed fermentation on the mixed material at 35 DEG C for 50-60 hours to obtain a fermented material, and performing vacuum concentration and drying on the fermented material to obtain the biological peptide. According to the invention, the low-value fish processing by-products can be converted into the biological peptide with excellent feeding value and nutritional value.

Description

technical field [0001] The invention relates to a method for recovering low-value fish processing by-products. Background technique [0002] At present, with the development of my country's aquaculture industry and the promotion and popularization of modern fishing technology, fish resources are being destroyed, and low-value aquatic products such as small fish and shrimps are rapidly multiplying, while the development of aquatic product processing industry is relatively slow compared with developed countries. Among the products, there are many primary products, but few deep-processed and refined-processed products, resulting in a large amount of leftovers, accounting for about 28%. A large number of by-products (about 3.9 million tons) are produced after rough processing of aquatic products. Wastewater is about 8 million tons. These low-value fish processing by-products, especially the high-protein water part after processing and cooking, are discarded, and the rest is used ...
