Abstract

The invention relates to a purifying method for bivalve molluscs. The method comprises the following steps that: (1), primary purification is carried out; to be specific, bivalve molluscs are cultivated in first purifying water temporarily and dactylococcopsis acicularis is placed for purification processing for 2 to 5d, wherein the first purifying water is natural seawater that is added with a immunopotentiator and is used for keeping continuous ultraviolet irradiation; and (2), secondary purification is carried out; to be specific, the bivalve molluscs after primary purification are cultivated in second purifying water temporarily and dactylococcopsis acicularis is placed for purification processing for 3 to 5d, wherein the second purifying water is natural seawater that is added with a immunopotentiator and is used for keeping continuous ultraviolet irradiation. Compared with the prior art, the provided purifying method has the following beneficial effects: with the primary and secondary purification method, biological danger from bacteria and viruses of the bivalve molluscs can be eliminated step by step, thereby substantially reducing purification processing time and improving the purifying effect; and after implementation of the method after one weak, the bacteria of the bivalve molluscs can be eliminated about 90% and the virus elimination rate can reach over 95%, thereby meeting the food sanitation standard.

Description

technical field [0001] The invention relates to the field of purification of edible seafood, in particular to a method for purification of bivalve molluscs. Background technique [0002] Oysters, mussels, meretrix meretrix and other bivalve molluscs are rich in nutrients, high in vitamin content, and delicious in meat quality, and are deeply loved by people. In recent years, the edible safety of bivalve molluscs has been affected due to environmental pollution and the characteristics of bivalve mollusks living as filter-feeders at the bottom of the water. At present, domestic regular monitoring indicators include lead, arsenic, mercury, copper, cadmium, chromium and other heavy metal pollution and petroleum hydrocarbon indicators; PSP, DSP, NSP and other shellfish toxin indicators; Vibrio parahaemolyticus, diarrhea-causing E. coli , Salmonella, hepatitis A virus, coliform bacteria, total number of colonies and other pathogenic microorganism indicators. [0003] Bacteria, v...
