Embodiment 1

[0023] A method for preparing fishmeal from solid-state fermented aquatic product leftovers, comprising the steps of:

[0024] (1) Place the marine Rhodotorula and Bacillus subtilis on the potato sugar agar medium for slant culture; inoculate the marine Rhodotorula and Bacillus subtilis after the slant culture into the marine Rhodotorula and Bacillus subtilis Propagate the seed bottle culture medium, and inoculate the fermentation bottle with 5% inoculation amount of the bacterial liquid in the seed bottle of marine Rhodotorula and Bacillus subtilis according to the volume ratio of 2:1. Dried and ground to get marine rhodotorula-subtilis mixed bacteria powder; marine rhodotorula is rich in active substances such as β-glucan, mannan oligosaccharides, active polypeptides and astaxanthin, which can provide abundant fermentation for raw materials Nutrients and active peptides can inhibit inflammation and resist microbial infection, which is conducive to creating a healthy and harm...

Abstract

The invention discloses a method for preparing fish meal through solid state fermentation of leftovers of aquatic products. A microbial fermentation method is adopted for preparing fish meal; protective agent potassium sorbate and (S)-(+)-3-(1-naphthoxy)-1-phenyl-1-propyl alcohol are added in a preparation process of mixed microbial bacterial powder; the fermentation process is as follows: placinga fermentation medium into a disinfected shallow fermentation tray, covering a disinfected wet gauze on the surface of the fermentation medium in the shallow fermentation tray, and then placing the shallow fermentation tray onto a shelf in a disinfected solid fermentation room and fermenting, wherein the fermentation medium contains (Z)-3-hexenol and riboflavin. The invention has the beneficial effects as follows: leftovers of aquatic products are used as raw materials, so that lower cost is guaranteed; the microbial fermentation method is adopted for preparing fish meal, so that high temperature steaming of the traditional processing method is avoided and nutritional ingredients in the fish meal are prevented from being lost and damaged; the fish meal prepared according to the inventionhas the advantages of anti-microbial and antiviral properties and high digestibility.

Description

technical field [0001] The invention relates to the technical field of aquatic products, in particular to a method for preparing fish meal from solid-state fermented aquatic product leftovers. Background technique [0002] Fishmeal is the main raw material of high-protein feed. It is a powdery or granular product obtained from fish, shrimp, crab and other aquatic animals or aquatic product processing waste through deoiling, drying and crushing. With the rapid development of aquaculture and fishing industry, the demand for aquatic feed protein is also increasing. High-quality fish meal can promote the absorption and utilization of high-nutrient substances by aquatic animals such as fish and shrimp, and then promote the growth and reproduction of fish and shrimp, and occupies a dominant position in today's aquatic feed. [0003] With the rapid development of the aquaculture industry, the demand for feed protein is also increasing. Especially high-quality fish meal, because i...
