目的:了解广东省面制食品中铝污染的状况,并对居民来源于面制食品的铝摄入状况进行暴露评估。方法:2009年从广东省21个地市的超市、食杂店、集贸市场等随机采集面包、馒头、包子以及油饼油条类食品共840份,按照国家标准GB/T5009.182—2003《面制食品中铝的测定》方法测定其中的铝含量。将2002年广东省居民膳食营养与健康状况监测的调查人群按照不同的年龄、性别分成10组,分别计算面制食品消费量平均值和第97.5百分位数(P97.5)情况下各组人群铝的摄入情况。结果:面制食品中铝平均含量为210.30mg/kg,调查人群来自面制食品的平均铝摄入量0.10mg/(d.bw),为每日可耐受摄入量(Acceptable Daily Intake,ADI)的0.73倍,从总体上看,2002年广东省营养与健康状况监测调查人群来源于面制食品的铝摄入水平是安全的。面制食品消费量为第97.5百分位数的情况下,调查人群总的铝摄入量为0.61mg/(d.bw),为ADI的4.35倍,各组的铝摄入量平均值和第97.5百分位数铝摄入量分别为ADI的0.61—2.49倍、3.05—14.78倍,超出ADI倍数最高者为组1的2—7岁少年儿童。结论:需要关注广东省居民膳食铝食用安全情况,尤其是对生长发育阶段的少年儿童。在此基础上,尚需要纳入其它含铝高的食物调研,进行更加精细和全面的膳食铝健康危害风险评估。
OBJECTIVE: To understand the status of aluminum contamination in flour products in Guangdong Province and evaluate the exposure of residents to aluminum intake from flour products. Methods: In 2009, a total of 840 breads, steamed breads, buns and dough fritters were randomly collected from supermarkets, grocery stores and bazaars in 21 cities in Guangdong Province. According to the national standard GB / T5009.182-2003 Determination of aluminum in food "method to determine the aluminum content. According to different age and sex, the survey population of residents in Guangdong Province who were monitoring the dietary nutrition and health status in 2002 were divided into 10 groups, and the average value of the consumption of the noodle products and the 97.5th percentile (P97.5) Population aluminum intake. Results: The average content of aluminum in flour products was 210.30mg / kg, the average aluminum intake from flour products was 0.10mg / (d.bw), and the acceptable daily intake (Acceptable Daily Intake, ADI) 0.73 times. Overall, in 2002, the nutrition and health monitoring survey population in Guangdong Province was safe from the aluminum intake of flour products. In the case of pasta food consumption at the 97.5th percentile, the total aluminum intake of the surveyed population was 0.61 mg / (d.bw), 4.35 times that of the ADI, and the average aluminum intake and The 97.5th percentile of aluminum intake was 0.61-2.49 times and 3.05-14.78 times that of ADI respectively. The children aged 2-7 years beyond the highest ADI were Group 1 children. Conclusion: It is necessary to pay attention to the safety of dietary aluminum for residents in Guangdong Province, especially for children and adolescents during the growth and development stage. On this basis, there is still a need to include other high aluminum food research to conduct a more refined and comprehensive risk assessment of dietary aluminum health risks.
