摘要 目的分析河源地区5个产粮区的大米、市售常见品牌中6种玉米淀粉和河源2家城市自来水中铝元素的含量情况。方法对河源5个主要产粮区的共计200批次大米进行采样,对市售玉米淀粉随机抽取6个品牌共60批次样品,以及对河源两家饮用供水系统连续30 d取水样各30次,采用GB 5009.182-2017《食品安全国家标准食品中铝的测定》分别对大米、玉米淀粉和饮用水中铝元素进行测定。结果以欧盟确定的面制品中铝限量标准为参考,所抽的200批大米中,不合格样品有4批,总体不合格率为2.0%;所抽市售玉米淀粉铝60批,不合格样品有3批,总体不合格率为5.0%;东江河东源段供水系统中测定铝含量介于0.053~0.071 mg/L,平均含量为0.066 mg/L;新丰江供水系统中测定铝含量介于0.042~0.064 mg/L,平均含量为0.058 mg/L。估算出河源米粉原料带入的铝含量最高值为14.15 mg/kg。结论原料中铝检出情况证明河源米粉在不添加含铝添加剂的情况下也可能存在铝的残留,应引起相关部门的注意。同时建议尽快制定米粉制品中形态铝标准方法和米粉制品中铝元素限量标准。 Objective To analyze the aluminum content of rice in 5 kinds of grain-producing areas in Heyuanarea,6 kinds of corn starch in common brands,and the tap water from two water company in the cities of Heyuan.Methods A total of 200 batches of rice were sampled from 5 main grain-producing areas in Heyuan,60 batches of samples were randomly selected from 6 brands of commercially available corn starch,and water samples were taken from 30 drinking water systems in Heyuan for 30 consecutive days.Second,GB 5009.182-2017 National food safety standard-Determination of aluminum in food was used to determine aluminum content in rice,corn starch and drinking water.Results With European Union flour chinalco limited standard for reference,4 of the 200 batches of rice samples were unqualified samples and the overall disqualification rate was 2.0%;3 of 60 batches of commercially available corn starch were unqualified samples,with an overall failure rate of 5.0%.The aluminum content measured in the water supply system of the Dongyuan section of the Dongjiang river ranged from 0.053 to0.071 mg/L with an average content of 0.066 mg/L.The aluminum content measured in the Xinfengjiang water supply system was between 0.042-0.064 mg/L,with an average content of 0.058 mg/L.It was estimated that the highest aluminum content brought by Heyuan rice flour raw material is 14.15 mg/kg.Conclusion The detection of aluminum in raw materials proves that there may be aluminum residues in Heyuan rice flour without the addition of aluminum-containing additives,which should attract the attention of relevant departments.At the same time,it is recommended that the standard method of form aluminum in rice flour products and the aluminum element limit standard in rice flour products be formulated as soon as possible.
