An investigation of aluminium in deep-fried twisted dough sticks for breakfast in Baotou in 2009

目的:根据包头市卫生局2009年食品卫生安全检测安排,调查我市范围内各类餐饮服务场所油条中的含铝量。方法:铬天青S分光光度法。结果:采集油条样品52件,铝含量最大值为750.6 mg/kg,最小值为11.5 mg/kg,平均值为238.9 mg/kg。结论:我市个体摊点、饭馆出售的油条铝多数不合格,超标率为64.4%,这是由于生产经营者管理不善,不当使用食品添加剂造成的,建议市民少食用这两个场所销售的油条;快餐连锁店的油条铝均合格,可以放心食用。
