摘要
目的研究食品用蜜胺制品中三聚氰胺迁移量的迁移规律。方法采用高效液相色谱法测定60、75和90℃三个模拟温度下三聚氰胺从食品用蜜胺制品中迁移至3%乙酸、15%乙醇两种模拟溶剂的量。根据所得的试验数据,讨论不同温度和不同食品模拟物的选择对三聚氰胺迁移行为的影响,以及样本重复10次进行迁移实验时三聚氰胺迁移量的变化规律。结果三聚氰胺迁移至3%乙酸模拟溶剂中的量较迁移至15%乙醇模拟溶剂的量高。其量值约为迁移至15%乙醇模拟溶剂的1.54～33.3倍,且其迁移量随着模拟温度的升高和增多;经过10次迁移后,仍有三聚氰胺迁出,但迁移量均不高。单次最大迁移量值为0.0851mg/dm2,其值约为欧盟规定的SML值的1/59。结论 3%的乙酸是最苛刻的模拟溶剂,温度越高迁移量越大,且经过多次重复使用后三聚氰胺仍有迁移。
Objective To study the migration rules of melamine in products of tripolycyanamide for food packaging.Methods With different stimulant solutions,temperatures exposure and long term use,the migration quantities of melamine in products of tripolycyanamide for food packaging into 3% acetic acid and 15% ethanol were measured by HPLC method.Results The amounts of melamine migrated to 3% acetic acid was higher than those to 15% ethanol.Higher temperatures more amounts of melamine of products of tripolycyanamide were migrated.With the higher temperature exposure was done,the amount of melamine migration reached maximum in lower number of repeated exposures.After 10 times of migration tests,melamine still can be migrated but the amount was not high.The single maximum migration amount was 0.0851 mg/dm2,and the value was approximately 1/59 of the SML regulated by EU regulations.Conclusion 3% acetic acid is the most serious solvent.The higher the temperature,the greater the migration,and melamine still migrate after repeated use.
