我国山东、辽宁两省黄海胆生殖腺中微量元素分布特征
目的 研究我国山东省和辽宁省黄海胆生殖腺中营养元素的分布特征。方法 本研究选取了辽宁和山东2个省份的6个地区(45份样品), 依据GB 5009.268-2016采用电感耦合等离子体发射光谱仪(inductively coupled plasma optical emission spectrometry, ICP-OES)和电感耦合等离子体质谱仪(inductively coupled plasma mass spectrometry, ICP-MS)对黄海胆生殖腺中微量元素的含量进行测定, 并研究其分布特征。结果 6个地区的黄海胆中10种微量元素分布各不相同, 海阳总量含量最高, 为1.57×103 mg/kg; 是含量最低的小平岛的1.8倍。SPSS软件分析黄海胆中微量元素含量地区间的差异性, 发现Zn、Ni、Se、Fe、V、Mn、Co和Cr的P值小于0.05, 具有一定的统计学意义。单元素含量占前3位的元素依次是Zn、Ni和Sr。微量元素中Zn的含量最高, 范围为278~865 mg/kg, 含量最高地区是最低地区的3.1倍, 地区差异较大。海胆中Sr的含量较高, 范围为119~184 mg/kg, 但是地区性差异较小。结论 黄海胆含有丰富的微量元素, 除Fe外, 其他元素大都超过海参中的元素含量, 是很好的微量元素补充膳食食品。地区差异性有统计学意义的微量元素(P<0.05)可以考虑作为海胆产地识别的指纹元素进一步研究。
Objective To study the distribution characterization of trace element in gonads of Glyptocidaris crenularis (GC) from Shandong province and Liaoning province in China. Methods All the 45 samples collected from 6 districts of Liaoning and Shandong province were detected. According to GB 5009.268 2016, the content of trace element in GC gonads were investigated by inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS), and the distribution characteristics were studied. Results The distribution of trace element in GC from 6 districts were different obviously. The total content of trace elements of GC from Haiyang with the highest content (1.57×103 mg/kg) was 1.8 times more than that from Xiaopingdao with the lowest content. Significant difference of regional disparity of Zn, Ni, Se, Fe, V, Mn, Co and Cr was found among the 6 districts analyzed statistically by SPSS 16.0(P<0.05). The trace element of the top 3 in turn was Zn, Sr and Ni. The content of Zn in the trace elements was the highest, ranging from 278 to 865 mg/kg. The content of Zn in the area with the highest content was 3.1 times of that in the area with the lowest content. The content of Sr in GC was high, ranging from 119 to 184 mg/kg, but the regional difference was small. Conclusion The trace elements of GC are richer than that of sea cucumber except Fe. GC is a good kind of trace elements supplement dietary food. The trace elements with statistical significance in regional difference (P<0.05) can be used to classify the GC geographical origin by multi-element analysis for further study.
