Selenium is an essential trace element for the human body,and organic selenium possesses important physiological functions such as antioxidation and immune enhancement.This study detecte the selenium forms in pike crab and conducte an analysis of the degradation regularity of different selenium forms in the pike crab at different temperatures.Results indicate that,pike crab contains five forms of selenium elements,whose content from high to low are selenomethionine(SeMet),methyl-selenocysteine(MeSeCys),selenocystine(SeCys2),selenite[Se(VI)]and selenite[Se(IV)].The rate of degradation of inorganic selenium in pike is relatively fast and that of organic selenium is relatively slow at room temperature and 4℃.It is beneficial to slow down the degradation rate of selenium and stabilize the nutritional and sensory quality of pike crabs at low temperature environment.These data provide certain guiding significance for maintaining and protecting the quality of pike crabs.
