Abstract

The invention relates to the technical field of marine toxin removing, and particularly relates to a method for removing shellfish toxin. The method comprises the following steps: soaking shellfish ina pretreatment solution; performing antioxidant solution treatment, and draining and packing the shellfish; freezing the shellfish at the temperature of negative 2 to negative 4 DEG C, and performingirradiation treatment; and performing freezing treatment at the temperature of negative 2 to negative 4 DEG C, and performing storage under the condition of 4-8 DEG C. According to the method, heavymetals and shellfish toxin in shellfish bodies can be effectively removed, and the shellfish can meet the safety requirement of foods; and furthermore, the taste and color of shellfish products are not influenced in the treatment process, antioxidant addition is not required in the preparing process, the shellfish product prepared by the method has the advantages of long preservation period and noother adverse smell, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of removing marine toxins, in particular to a method for removing shellfish toxins. Background technique [0002] Marine shellfish is deeply loved by people because of its delicious taste and high nutritional value. However, with the aggravation of coastal environmental pollution, shellfish as filter-feeding organisms have a strong ability to adsorb and accumulate toxic algae and some heavy metal ions, and humans are prone to shellfish toxins after eating shellfish that have accumulated toxic algae and heavy metals phenomenon of poisoning. Therefore, researching and developing a method that can effectively remove shellfish toxins in shellfish is a difficult problem to be solved urgently at present. [0003] Patent document CN104621228A discloses a method for promoting the discharge of paralytic shellfish poison in shellfish, the method is to use woody activated carbon particles to promote the discharge o...
