中文摘要:

      目的 研究食用动物皮中重金属本底值, 更加有效地实施对动物皮及其制品中的重金属含量监测。方法 从河南省14个省辖市的市场上采购286份食用动物皮样品进行重金属含量的检测, 5种重金属分别为铅含量(以Pb计)、镉含量(以Cd计)、总砷含量(以As计)、铬含量(以Cr计)、汞含量(以Hg计)。以GB 2762—2017《食品安全国家标准 食品中污染物限量》中肉类中重金属含量的限量值作为参考。结果 铬的超标率为8.5%, 检出范围为未检出(not detected, ND)~1.71 mg/kg, 铅的超标率为7.7%, 检出范围为ND~1.33 mg/kg, 镉的超标率为3.1%, 检出范围为ND~0.172 mg/kg。结论 本研究可以为进一步制定食用动物皮中重金属的限量标准和市场的科学监管提供依据。

英文摘要:

      Objective To study the background value of heavy metals in edible animal skins, and to monitor the content of heavy metals in animal skins and their products more effectively. Methods A total of 286 samples of edible animal skin purchased from the markets of 14 provinces and cities in Henan province were tested for heavy metal content, the 5 heavy metals were lead (Pb), cadmium (Cd), total arsenic (As), chromium (Cr) and mercury (Hg). The limit values of heavy metal content in meat in GB 2762—2017 National food safety standard-Contaminant limits in foods were taken as a reference. Results The exceeding standard rate of chromium was 8.5%, the detection range was ND-1.71 mg/kg, the exceeding standard rate of lead was 7.7%, the detection range was ND-1.33 mg/kg, and the exceeding standard rate of cadmium was 3.1%, the detection range was ND-0.172 mg/kg. Conclusion This study could provide a basis for further development of heavy metal limit standards in edible animal skin and scientific supervision of the market
