Analysis of Inorganic Element Content in Sanmen Green Crab
In order to understand the content of inorganic elements in Sanmen green crab from various origins in Sanmen county,12 kinds of inorganic elements in Sanmen green crab were measured using inductively coupled plasma mass spectrometry and f lame atomic absorption photometry.The results show that the pollutant element index of Sanmen green crab from various producing areas in Sanmen county is far lower than the limit standard of pollutants in food.Sanmen green crab are rich in trace elements such as Se,Ca and Zn.There was no significant difference in Cu,Mg and Zn element contents among Sanmen green crab from various origins(P＜0.05).Except for Cr,Zn,Al and Mg elements,the accumulated amounts of inorganic elements in blue crab gonadal tissue are greater than those in muscle tissue.Principal component analysis showed that there was no obvious correlation between the inorganic element content of Sanmen green crab and the origin,indicating that the inorganic element content of green crab from various producing areas in Sanmen county had good uniformity.
