南宁市部分面制食品中铝含量调查

The survey of aluminum content in Nanning flour foods

目的了解南宁市区几种常见面制食品中铝的含量,探寻铝污染食品的影响因素,为监管部门制定防制措施提供依据。方法在南宁市区酒店、学校和街头零售摊位随机抽取油条28份、糕点32份和膨化食品10份样品进行检测和评价。结果 3类常见面制食品铝含量范围为42.8～120 6 mg/kg,平均含量为336.7 mg/kg。油条中90%的样品铝含量在320～120 6 mg/kg之间;3类面制食品铝的总体超标率为60.0%,油条、糕点、膨化食品铝超标率分别为92.9%、46.9%、10.0%;酒店、学校和街头零售摊位的油条糕点类面制食品中铝超标率分别为65.8%(25/38)、53.8%(7/13)、100.0%(9/9),现做现卖的油条糕点类面制食品比定型包装的膨化食品的铝超标率高。结论南宁市面制食品中铝超标严重,建议进一步加强食品安全监管力度。

Objective To find out the aluminum content of some common flour foods in Nanning, search the influencing factors and provide basis for the regulatory authorities to develop control measures. Methods 28 crullers, 32 cakes and 10 pieces of puffed food were randomly collected from the retail stores of hotels, schools, and booths and then tested and evaluated. Results The aluminum content of three common flour foods was in the range of 42. 8 - 1 206 mg/kg, and the average was 336.7 mg/kg. The aluminum content of 90% cruller was in the range of 320 - 1 206 mg/kg. The overall over standard rate of the three flour foods was 60% , and was 92. 9% , 46.9% and 10. 0% for cruller, cakes and puffed food, respectively. The over standard rate of cruller and cakes from retail stores of hotels, schools and booths was 65.8% （25/ 38） , 53.8% （7/13） and 100. 0% （9/9） , respectively. The on-site products had a higher aluminum content than the prepackaged puffed food. Conclusion The aluminum content of flour foods in Nanning was seriously over standard, and further actions to strengthen food safety supervision was highly recommended.
