Objective To evaluate residual aluminum concentrations in food with aluminum additives in Yunnan province and provide scientific basis for healthy food guidance and food security.Methods A total of 1255 samples were collected from different places in Yunnan province by stratified random sampling method according to diet habit of local people.Concentrations of residual aluminum in samples were analyzed using uniform method of national standards.Results The detection of food additives aluminum residue is different in different food categories,and fried noodles products had the highest exceeded rate of 62.1％.The aluminum residue in the local characteristic food milk rushan was also high,and it was up to 50.8％,which were more than 0.1 g/kg.Followed by wheat flour and its products,puffed food,samples with residual aluminum more than 0.02 g/kg were 34.4％ and 34.1％.The exceeded rate of aluminum in jellyfish was 38.5％.Foods with low aluminum residues were baking food and vermicelli,with exceeded rate of 2.40％ and 7.14％,respectively.Conclusion Aluminum additives are widely used in food,giving rise to illegal use of additives and health risks.Propaganda and education of food safety are necessary for local people.The publicizing of changes of the standards should be strengthened,and the crackdown on illegal dealers should be intensifies.Food processing improvement and safety standards setting for local food like rushan are recommended.%目的 了解云南省含铝食品添加剂的添加使用状况及残留情况,为有效开展居民健康饮食指导、保障食品安全提供依据.方法 采用分层随机抽样的方法,根据云南当地居民饮食习惯,随机抽取全省共1255份样品,按国家统一的方法进行检测,并分析含铝添加剂铝残留情况.结果 不同食品类别食品添加剂铝残留量的检出情况不同,油炸面制品超标率最高为62.1％,地方特色食品乳扇铝残留量也较高,超过0.1 g/kg的样品达50.8％;其次为小麦粉及其制品、膨化食品,超过0.02 g/kg的样品为34.4％和34.1％;海蜇铝的残留量超标率为38.5％;铝残留量较低的食品为焙烤食品和粉丝、粉条,超标率分别为2.40％、7.14％.结论 含铝食品添加剂使用普遍,超标和非法添加现象不容忽视,应加强对百姓食品安全知识的宣传、教育,对标准的变化加强宣贯,对不法商贩加大打击力度.改进工艺,对于乳扇等地方食品加强标准建设.
