Processing method and application of fermented feed for aquatic products based on hermetia illucens

Abstract

The invention belongs to the field of biological feed, and specifically relates to a processing method and application of fermented feed for aquatic products based on hermetia illucens. The method comprises the following steps: activating a strain to obtain a bacillus fermentation seed solution, a saccharomycetes fermentation seed solution and a lactic acid bacteria fermentation seed solution; mincing and homogenizing fresh hermetia illucens larvae, and then mixing with bran, rice bran and wheat middling, adding acid protease, conducting mixing to obtain a fermentation culture medium, inoculating the bacillus fermentation seed solution, the saccharomycetes fermentation seed solution and the lactic acid bacteria fermentation seed solution, conducting anaerobic fermentation under the closed condition, and then obtaining a finished product. According to the present invention, fresh hermetia illucens are adopted for bacterium-enzyme synergistic fermentation, fermentation is thorough, and the finished product is high in small peptide content and rich in organic acid and has antibacterial activity; and meanwhile, the storage time is long, use is convenient, and good economic benefits are achieved.

Description

technical field [0001] The invention belongs to the field of biological feed, and in particular relates to a processing method and application of fermented feed for aquatic products based on black soldier flies. Background technique [0002] Aquafeed accounts for 40% to 60% of the cost of aquaculture. Fishmeal is one of the most important feed protein sources in aquaculture feed. More than 2 / 3 of fishmeal is used as aquafeed in the world, and it reaches about 60% in China. With the rapid development of the aquaculture industry, the problem of global fishmeal resource shortage is becoming more and more severe, and aquafeed relies on fishmeal and fish oil extracted from bait fish, resulting in an increase in the cost of aquaculture and seriously restricting the sustainable development of the aquaculture industry. Black soldier fly is a kind of insect of Diptera Soldier Fly family. It is widely distributed. Its larvae are rich in essential amino acids, among which the content o...

AI Technical Summary

Problems solved by technology

Black soldier fly powder drying and crushing equipment requires large investment and high energy consumption. High temperature treatment will destroy protein and high ash content, resulting in lower digestion and absorption rate of the body; in addition, feeding black soldier fly fresh worms whole or chopped, these are not denatured The protein may affect the digestion and absorption rate and reduce the growth performance of the body. Some small aquatic animals have small mouths and cannot directly eat the black soldier fly body. At the same time, the black soldier fly body has the risk of carrying viruses and bacteria. For different aquatic animals, black soldier fly The appropriate amount of adding fresh soldier flies varies; black soldier flies have different life cycles, black soldier fly larvae can be used for aquatic feeding, black soldier fly pupae or adults are difficult to use, so black soldier fly storage and transportation There are difficulties
