Preparation method of nonreactive aquatic product immunity enhancer

Abstract

The invention relates to the field of aquaculture and discloses a preparation method of a nonreactive aquatic product immunity enhancer. The preparation method comprises the following steps: (1) uniformly mixing 80 to 120 parts of aquatic product polypeptide, 40 to 60 parts of camellia seed meal modified extract, 10 to 30 parts of astaxanthin, 10 to 30 parts of fucoxanthin, 10 to 20 parts of pearl powder, 40 to 80 parts of seaweed extract and 300 to 500 parts of water to obtain a component A; (2) dissolving 20 to 30 parts of calcium chloride into 500 to 700 parts of water to obtain a component B; (3) dropwise adding the component A into the component B at the speed of 0.5mL / s to 1.5mL / s to produce solid sediment; filtering, taking the solid sediment and drying to obtain the nonreactive aquatic product immunity enhancer. The nonreactive aquatic product immunity enhancer provided by the invention is prepared from pure natural green raw materials and does not contain antibiotic drugs; the immunity of aquaculture animals can be effectively improved by the nonreactive aquatic product immunity enhancer, and the nonreactive aquatic product immunity enhancer does not cause pollution to the breeding environment and is green and environment-friendly.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a preparation method of an anti-antibiotic-free aquatic immunity enhancer. Background technique [0002] In recent years, with the rapid development of the aquaculture industry and the increase in high-density intensification, problems such as the deterioration of the aquaculture environment, the degradation of germplasm resources, and disease infections have increased year by year. Improving the autoimmunity of aquaculture animals is one of the ways to resist diseases. [0003] The current main way to improve the immunity of aquaculture animals is to add antibiotics to aquatic feed. However, in recent years, the abuse of antibiotics and other drugs has been serious. Not only have fish, shrimp, and crabs died on a large scale, but also the drug residues in some aquatic products have increased or seriously exceeded the standard, seriously threatening food safety. In addition, the inspe...

However, in recent years, the abuse of antibiotics and other drugs has been serious. Not only have fish, shrimp, and crabs died on a large scale, but also the drug residues in some aquatic products have increased or seriously exceeded the standard, seriously threatening food safety.

In addition, the inspection of aquatic products in major aquatic product importing countries such as Europe, America and Japan has become increasingly strict, which has also affected the export of aquatic products and caused huge economic losses to my country's aquaculture industry.

At the same time, the accumulation of drugs in the water will pollute the aquaculture environment, further destroy the aquaculture ecological environment, and form a vicious circle
