Problems solved by technology

However, chloride is a chemical reagent, which is easy to produce toxic chloramines, thereby affecting the quality of shellfish; the third is physical methods, that is, the use of ultraviolet rays or ozone purification, which is currently the most commonly used purification method
Ultraviolet and ozone purification methods are affected by seawater turbidity, color, and soluble iron salt content, and have relatively large limitations

Abstract

The invention discloses a purification method of a cyclina sinensis finished product. The purification method comprises the following steps: washing an obtained cyclina sinensis finished product; removing sludge; putting into a temporary cultivation tank; during a cultivation period, adding a microalgae preparation into sand-filtered seawater, wherein the microalgae is a mixture of skeletonema, tetraselmis and dicrateria inornata which are mixed at a random ratio; after 5 hours, putting the cyclina sinensis finished product into another temporary cultivation tank; adding a microbial preparation into the sand-filtered seawater, wherein the microbial preparation contains agritol freeze-dried powder, bacillus subtilis freeze-dried powder, bacillus licheniformis freeze-dried powder, wild mushroom entity freeze-dried powder and diatomite; and culturing for 24-48 hours, renewing the water and further culturing for 4-8 hours to obtain a purified finished product. The purification method disclosed by the invention has the advantages of effectively removing heavy metals in the body of the cyclina sinensis within short time, having a quite good removal effect on escherichia coli, sphingomonas paucimobilis, vibrio and aeromonas salmonicida, and is simple to operate, short in purification time and extremely good in purification efficiency.

Description

technical field [0001] The invention relates to a shellfish purification method, in particular to a clam product purification method. Background technique [0002] Green clams belong to the branchial valve class, clam order, and clam family, commonly known as black clams, iron clams, clams, round clams, stone snails, etc. They are warm-water species and are distributed in the north and south coasts of my country. Its meat is delicious and nutritious, and belongs to high-protein food. Since the 1980s, when the research on artificial seedlings of green clams was carried out, satisfactory results have been obtained in earthen pond cultivation and industrial seedling cultivation of green clams. [0003] However, in recent years, with the rapid development of my country's industry and agriculture, the pollution of pollutants to the environment, especially water bodies, has become more and more serious. These pollutants are mainly divided into three categories: one is industrial ...
