中文摘要:

      目的 利用分光光度计法测定潮州市部分小作坊和超市销售的猪肉丸中硼酸的含量, 为有关监督管理部门提供依据参考。方法 参照GB 2760-2014《食品安全国家标准 食品添加剂使用标准》方法, 样品经富集、萃取, 显色后使用分光光度计检测猪肉丸中硼酸的含量。结果 本法线性良好, 线性范围为0~25 μg, 相关系数达0.9980, 回收率为92.0%~96.4%, 相对标准偏差为1.12%~2.31%。实际样品检测中, 20份测试样品中有3份检出硼酸, 其含量为15.0~31.4 mg/kg, 不合格率为15%。结论 该方法简单、回收率高、准确、可靠, 可适用于猪肉丸中硼酸的检测, 为相关部门提供管理依据。

英文摘要:

      Objective Determination of boric acid content in pork balls sold in some small workshops and supermarkets in Chaozhou by spectrophotometer, so as to provide references for the relevant supervision and management departments. Methods According to GB 2760-2014 National food safety standard-Standard for the use of food additives, the content of boric acid in Chaozhou pork pellets was detected by spectrophotometer after enrichment and extraction. Results This method had a good linearity in range of 0~25 μg, with the correlation coefficient of 0.9980. The recovery rates were 92.0%~96.4% and the relative standard deviations were 1.12%~2.31%. In actual sample detection, boric acid was detected in 3 samples among 20 samples, the content was 15.0~31.4 mg/kg, with the rate of disqualification of 15%. Conclusion The method is simple, accurate, reliable, and has high recovery, which is suitable for detection of boric acid in pork pellets and provide basis for relevant departments.
