2017—2018年达州市603份熟制米面食品中铝含量监测分析

Analysis of Aluminum Content in 603 Cooked Rice Flour Foods in Dazhou From 2017 to 2018

目的了解达州市熟制米面食品中铝污染现状,为有效开展居民健康饮食、保障食品安全提供理论依据。方法采用简单随机抽样方法于2017—2018年采集达州市通川区、达川区2个主城区及周边乡镇的超市、农贸市场、餐饮店、流动摊点和学校食堂等地点油炸、发酵、焙烤和膨化食品等23种熟制米面食品,进行铝残留含量检测,并将相关数据纳入Excel 2007和SPSS 21.0软件统计分析,率的比较采用χ^(2)检验,以P<0.05为差异有统计学意义。结果共采集603份熟制米面食品,铝残留整体超标率为14.93%,依次为发酵类27.66%、油炸类18.57%和膨化类11.46%,焙烤类仅检出1份超标,托面糊类全部合格。不同类别食品中、不同采样点铝含量超标率情况均有差异统计学意义(χ^(2)=14.45,P=0.034,χ^(2)=17.22,P=0.0017)。结论油炸食品和流动摊点超标较为严重,存在人为添加污染的可能性,需加大健康宣传和监管力度。

Objective To understand the status of aluminum pollution in cooked rice flour foods in Dazhou so as to provide a theoretical basis for the effective development of residents′healthy diet and food safety.Methods A total of 603 cooked rice flour foods were collected from 23 kinds of fried,fermented,baked and expanded foods from 2017 to 2018 by a simple random sampling method.The residual aluminum content was detected.The results were analyzed by using Excel2007 and SPSS 21.0 software.Chi-square test was used to compare the rates,and P<0.05 was considered as statistically significant(P<0.05).Results The overall exceeding rate of 603 cooked rice flour foods was 14.93%.The unqualified rate of fermentation was highest(27.66%),followed by frying(18.57%)and puffing(11.46%).Only one sample of baking exceeded the standard,whereas all the batters were qualified.There were significant differences in the exceeding standard rate of aluminum content in different types food and different sampling points(χ^(2)=14.45,P=0.034;χ^(2)=17.22,P=0.0017).Conclusion Fried food and mobile stalls exceed the standard seriously.There may be the possibility of artificial contamination.Health publicity and supervision should be strengthened.
