Fermented feed protein prepared from pineapple peel and processing method thereof

Abstract

The invention provides fermented feed protein prepared from pineapple peel and a processing method thereof. In the processing method, plant feed protein is mixed with pineapple peel juice and pineapple peel residue for fermentation so as to obtain high-quality plant fermented feed protein, which fully utilizes rich sugar, prolease and other beneficial components contained in the pineapple peel juice and the pineapple peel residue, achieves better fermentation and enzymolysis effect, increases small peptide content, obtains more complete and balanced nutrition and greatly reduces the strain consumption and the processing cost, thus providing a good approach for utilizing the pineapple peel juice and the pineapple peel residue, changing wastes into valuables and achieving multiple purposes at one stroke; and by adopting a distribution-packaging two-step fermentation method, the fermented product is directly bagged for sealed package or compressed for sealed package about 30 hours after the former fermentation stage, and subsequent fermentation of the fermented raw materials is completed during the subsequent storage and transportation process, thus the production rate is improved by more than one time, the production process is simple and feasible, the equipment investment and the production cost are low, and large-scale production is easily realized.

Description

technical field [0001] The invention relates to a fermented feed protein using pineapple peel and a processing method thereof. Background technique [0002] Seeking new protein sources to replace fish meal has always been the focus of the feed and aquaculture industry. Plant feed proteins such as soybean meal, rapeseed meal, and cottonseed meal have high protein content, rich and balanced essential amino acids, and rich sources, but there are proteins with high molecular weight and contain Excessive harmful anti-nutritional factors and toxins make soybean meal and other plant feed proteins difficult to be digested and absorbed by young animals and aquatic animals. Through solid-state fermentation of Bacillus subtilis, yeast and lactic acid bacteria, fermented soybean meal, fermented rapeseed meal and fermented Miscellaneous meal has been widely used in production, using the enzymatic hydrolysis of protease produced in the fermentation process to reduce the molecular weight o...

Problems solved by technology

[0005] The purpose of the present invention is to develop a method for the production of plant feed protein strains such as conventional fermented soybean meal, molasses, etc., which require a large amount of bacteria, high production costs, limited small peptide content in the fermented product, nutritional value to be improved, and long fermentation cycle. The fermented feed protein product and processing method of the skin, the invention makes full use of the rich sugar, bromelain and other beneficial ingredients contained in the pineapple peel juice and pineapple residue, and processes the pineapple peel juice, pineapple residue and plant feed protein through mixed fermentation Become a high-quality plant feed protein. While realizing the comprehensive utilization of pineapple peel juice and pineapple residue, the plant feed protein can obtain better fermentation enzymolysis effect, and the fermented feed protein obtained is more comprehensive and balanced in nutrition. And its squeezed juice has found a good way to use it, turning waste into treasure, killing several birds with one stone
