目的了解吉林省市售腐竹、肉丸、面粉、凉粉中硼的含量情况,为吉林省食品安全风险监测工作提供数据积累。方法随机采集吉林省内市售的腐竹、肉丸、面粉、凉粉的样品各20份,压力消解-电感耦合等离子体质谱法(ICP-MS)测定硼含量。结果硼元素普遍检出,面粉、凉粉、肉丸的检出值较集中,一般含量在5 mg/kg以下,腐竹中80%的样本含量集中在20 mg/kg以下,其余4份腐竹样本的含量较高。结论参照WHO推荐成人日摄入量安全范围规定,日常使用肉丸、面粉、凉粉及部分腐竹样本不会对人体造成明显的毒害作用。对于含量较高的4份腐竹样本,存在生产过程中添加硼砂的可能性,若误食,易威胁到人体健康。
Objective To understand the content of boron in commercial dried yuba, meatballs, flour and jelly in Jilin Province and to provide data for the food safety risk monitoring in Jilin Province. Methods Twenty samples of dried bean sprouts, meatballs, flour and jelly were collected randomly from Jilin Province. The content of boron was determined by pressure digestion-inductively coupled plasma mass spectrometry (ICP-MS). Results The boron content was generally detected. The detection values of flour, jelly powder and meatball were more concentrated, the contents were below 5 mg / kg, 80% of the yuba samples were concentrated below 20 mg / kg, and the remaining 4 yuba samples High content. Conclusion According to WHO recommended adult daily intake safety limits, daily use of meatballs, flour, jelly and some yuba samples will not cause significant toxic effects on the human body. For the higher content of 4 yuba samples, there is the possibility of adding borax in the production process, if the wrong food, it is easy to threaten human health.
