食品中硼酸及硼酸盐污染分布研究

目的了解市售食品中硼酸及硼酸盐的污染及分布情况,发现危险因素。方法采集市售食品面粉制品、豆制品、米制品、水产品及其他类食品共335件,采用分光光度法测定样品中硼酸的含量。结果面粉制品中硼酸及硼酸盐的检出率为40%;豆类及制品中全部检出,其含量主要集中在200mg/kg以下范围;水产品中检出率达84%;米制品中检出率最低为11%。结论市售食品中存在不同程度的硼酸及硼酸盐的污染,有一定安全隐患,相关部门应针对性加强监管,预防食源性疾病的发生,同时科学、合理区分本底和违法添加。

Study on pollution distribution of boric acid and borate in food

Objective To understand the pollution and distribution of boric acid and borate in commercial foods and find the risk factors. Methods A total of 335 samples of commercially available food including flour products, soy products, rice products, aquatic products and other foods were collected, and the content of boric acid in the samples was determined by spectrophotometry. Results The detection rate of boric acid and borate in flour products was 40%. Beans and products were all detected, the content of which was mainly concentrated in the range below 200 mg/kg. The detection rate of aquatic products reached 84%, the lowest detection rate of rice products was 11%. Conclusion There are different degrees of contamination of boric acid and borate in foods on the market, posing certain safety hazard. Relevant departments should reinforce supervision to prevent the occurrence of foodborne diseases, and distinguish the background and illegal additions in a scientifically reasonable way.
