Stichopus japonicus feed capable of decreasing dissolution velocity of chitosan oligosaccharide and preparation method of feed

Abstract

The invention discloses a stichopus japonicus feed capable of decreasing the dissolution velocity of chitosan oligosaccharide. The feed is prepared from, by mass, 50%-70% of gulfweed, 3%-7% of flour, 8%-11% of fish meal, 4%-8% of bean pulp, 8%-12% of marine mud, 2%-6% of premix, 0-3% of two-layer coated chitosan oligosaccharide and the balance microcrystalline cellulose. The two-layer coated chitosan oligosaccharide is obtained through a following method which comprises the steps that carboxymethylcellulose is put in water of 60 DEG C to be fully dissolved, and obtained carboxymethylcellulose coats chitosan oligosaccharide; carrageenan is put in water of 80 DEG C to be dissolved to be colloidal, colloidal carrageenan and the chitosan oligosaccharide coated with carboxymethylcellulose are fully mixed to be uniform, the two-layer coated chitosan oligosaccharide is obtained, and the effective content of the chitosan oligosaccharide in the two-layer coated chitosan oligosaccharide ranges from 30% to 35%. The stichopus japonicus feed can effectively decrease the dissolution velocity of the chitosan oligosaccharide in water. The invention further discloses a preparation method of the feed.

Description

technical field [0001] The invention relates to the field of feed for aquaculture, in particular to a japonicus japonicus feed that reduces the dissolution rate of chitosan oligosaccharides, and a preparation method of the japonicus japonicus feed. Background technique [0002] Apostichopus japonicus is one of the important mariculture species in northern my country. With the improvement of human living standards and the enhancement of health awareness, the demand for sea cucumbers has increased significantly. In order to solve the current situation of short supply, artificial breeding has developed rapidly, but it has also caused another major problem. In order to ensure production and prevent diseases, the abuse of chemicals and Antibiotics have brought serious environmental pollution and food safety hazards that humans are increasingly paying attention to. In order to avoid problems such as residues and drug resistance caused by the abuse of antibiotics, it is urgent to ...

AI Technical Summary

Problems solved by technology

The reason is that the eating method of sea cucumber is licking, feeding with tentacles and non-selective, and the action is slow, so the feed fed is often not ingested in time; and chitosan is easily soluble in water, if the chitosan is simply When added to sea cucumber feed, a large amount of chitosan oligosaccharides will be dissolved in water before the feed is ingested by sea cucumbers
