金环胡蜂食用虫态矿质元素含量分析

以微波消解法处理金环胡蜂(Vespa mandarinia Smith)4种食用虫态即幼虫、初化蛹、老熟蛹和成虫,采用电感耦合等离子体发射光谱法(ICP-OES)对这4种食用虫态样品中的K、P、S、Ca、Mg、Fe、Cu、Co、Mn、Se、Zn、Ba、Al、Cd等14种矿质元素成分进行了分析。结果表明:金环胡蜂各食用虫态中的K、P、S、Ca、Mg、Fe、Zn和Se等元素含量特别丰富,具有较高的食用价值;有害元素中Cd的含量为0.09～0.36μg/g,尚在国家食品污染物限量范围内,而Al的含量96.78～320.52μg/g,偏高。

Analysis of Mineral Elements Content in the Edible Stages of Vespa mandarinia Smith

The vespa mandarinia Smith samples in four edible stages,such as larvae,immature pupas,mature pupas and adults were respectively digested by microwave,and the digestion solution was directly injected into inductively coupled plasma optical emission spectrometer(ICP-OES)for quantitative determination of 14 mineral elements(K、P、S、Ca、Mg、Fe、Cu、Co、Mn、Se、Zn、Ba、Al and Cd).The results showed that the four edible stages contained rich components of K、P、S、Ca、Mg、Fe、Zn and Se,and had high edible value.The content of harmful element of Cd(0.09-0.36 ug/g) was in the national food contaminants limited range,and the content of Al(96.78～320.52 ug/g) was a little high.
