摘要
为了研究食品用铝箔在食品模拟液中的溶出规律,为铝箔在日常生活中的规范使用提供理论依据。参照国标对10个市售品牌铝箔进行质量评价,选取质量不同的铝箔,在不同浸泡条件下分析其在食品模拟液和调味品模拟液中铝的溶出规律。结果表明:随机抽检的10个市售铝箔品牌的质量存在一定的差异,其主要问题是重金属含量超标;随着浸泡时间的延长,浸泡温度的升高,铝箔在食品模拟液及调味品模拟液中铝溶出量出现不同程度增多;3种食品模拟液中,乙酸对铝溶出量的影响最大,乙醇次之,水对其影响最小;不同质量浓度调味品模拟液之间有显著性差异(p<0.05);国家规定的4%乙酸中铝溶出量高于欧盟规定的3%乙酸中铝溶出量,但65%乙醇铝溶出量低于欧盟规定的10%乙醇中铝溶出量;在相同的模拟液和浸泡条件下,劣质铝箔铝溶出量明显高于优质铝箔。
The aim of this study was to investigate the pattern of aluminum migration from aluminum foil used for food packaging in food simulation and to offer a theoretical basis for aluminum foil specification used in everyday life. According to the national standards, 10 brands of aluminum foil sold in market were evaluated. The aluminum foils with different qualities were used to determine the pattern of aluminum migration in different in food simulation and condiment simulation at different soaking conditions. The results showed that there was difference in quality among the 10 brands of aluminum foil and the main problem was the excess of heavy metal content. With the increase of soaking time and soaking temperature, the amount of aluminum released in food simulation and condiment simulation showed different degrees of increase. The effect of acetic acid on aluminum migration was the biggest among three types of food simulation. The migration of aluminum from aluminum foil in water was lower than that in ethanol solution. There were significant difference between concentrations of condiment simulation （p〈0.05）. The amount of migration in 4% acetic acid was higher than that in 3% solution, whereas it was lower in 65% ethanol than in 10% solution. In same simulate solution and under same conditions, the amount of aluminum released from the aluminum foil with poor quality was higher than those from superior quality.
