2009-2011年张家港市市售面制品中铝含量监测结果分析

Analysis on the Aluminum content in flour-made food in Zhangjiagang during 2009-2011

目的了解张家港市各类市售面制品的铝污染水平,为相关食品的监管提供依据。方法 2009-2011年在张家港市各乡镇主要超市、制售门店、集体食堂和小吃店等随机抽取各类面制品591份,按《面制食品中铝的测定》GB/T 5009.182-2003、《食品中污染物限量》GB 2762-2005进行检测与评价。结果 591份面制品铝含量总超标率为38.07%,呈逐年下降趋势;其中油条的超标率最高,为82.67%,其次为馒头/花卷(38.16%)、油炸食品(26.67%)、膨化食品(2.36%),不同类别面制品铝含量超标率差异有统计学意义(P<0.01);采自小吃店、制售门店、集体食堂、超市面制食品铝超标率分别为48.06%、47.90%、32.61%、11.89%,不同采样地点面制食品铝含量超标率差异有统计学意义(P<0.01)。结论张家港市部分市售面制品铝含量超标严重,存在人群过量暴露的潜在危害,需加强相关领域的宣传教育、培训和监督管理。

Objective To investigate the aluminum contamination in commercial flour-made food sold in Zhangjiagang. Methods A total of 591 samples were randomly selected from the supermarket, manufacturing and selling store, group canteen and small restaurant in Zhangjiagang. The detection and evaluation were conducted for the samples with the national standard of GB/T 5009. 182--2003 and GB 2762--2005. Results It showed that the under-standard rate of flour-made food has decreased from 55.00~ to 28.26o//oo for 3 consequent years. The total under-standard rate was 38.07~ ,of which twisted cruller was the highest （82.67 ~）, and the following in order were steamed bread/steamed roll （aS. 16 ~）, oil fried food （26. 67~//oo ） and puffed food （2.36 ~）. In addition, the samples collected from small restaurant and manufacturing and selling store with under-standard rates were 48.06%, 47.90%, 32.61% and 11.89% ,respectively. It was shown that statistical signifi- cances existed between different categories of flour-made food and different places to collect samples. Conclusion The alumi- num contamination in part of the commercial flour-made food in Zhangjiagang was serious, which means a potential risk of pop- ulation over-dosed exposure, so supervision and management needed to be enhanced by relevant facilities.
