摘　　要：建立食品模拟物中甲醛的迁移量和真实食品中甲醛含量的HPLC测定方法,调查了60℃、10 d迁移条件下4%(体积分数)乙酸对涂层金属罐的腐蚀情况。以环氧涂层中典型的挥发性物质甲醛为研究对象,研究了6种食品模拟物模拟21种金属罐装酸性食品的适用性。结果表明,在模拟食品长期贮存条件(60℃,10 d)下,19%的金属罐灌装乙酸溶液后发生了腐蚀;对于发生乙酸腐蚀的空罐样品,建议采用5 g/L柠檬酸作为此类产品用空罐中甲醛迁移量的食品模拟物。对于未发生乙酸溶液腐蚀的空罐样品,采用3 g/L与5 g/L柠檬酸及10%(体积分数)乙醇作为食品模拟物会导致超过80%的酸性罐装食品中甲醛含量的低估,此时推荐4%(体积分数)乙酸作为此类产品用空罐的甲醛迁移量测试的食品模拟物。In this study,the HPLC method was established to determine the migration of formaldehyde in food simulates and the content of formaldehyde in real food.The corrosion of 4%(volume fraction)acetic acid on coated metal cans was investigated under 60℃and 10-day migration conditions.The typical volatile substance formaldehyde in epoxy coatings was used as the research object,and six food simulants to simulate the applicability of 21 acid foods in metal cans.Results showed that 19%of the metal cans filled with acetic acid solution corroded under the long-term storage conditions(60℃,10 days)of the simulated foods.For the empty can samples in which acetic acid solution corrosion occurred,5 g/L citric acid was recommended as the food simulant for empty cans with such products.For the empty can samples without acetic acid solution corrosion,the use of 3 g/L and 5 g/L citric acid and 10%(volume fraction)of ethanol as food simulants would lead to underestimation of formaldehyde content in more than 80%of acidic canned foods,at this time,4%(volume fraction)of acetic acid was recommended as a food simulant for formaldehyde migration testing in empty cans for such products.
