目的：研究 AS(丙烯腈-苯乙烯)和 ABS(丙烯腈-丁二烯-苯乙烯)塑料食品接触材料中丙烯腈的迁移行为。方法采用顶空气相色谱法测定丙烯腈在不同食品模拟物和不同条件下的迁移量,研究食品模拟物、温度和时间对丙烯腈迁移量的影响,并和丙烯腈单体残留量作对比。结果 AS塑料食品接触材料中丙烯腈迁移量要高于ABS塑料；在相同的使用时间和温度下,50%乙醇模拟物中丙烯腈的迁移量最大；在同种食品模拟物中,丙烯腈迁移量随着接触时间的延长、接触温度的升高而增加。结论 AS塑料食品接触材料与ABS塑料食品接触材料相比, AS塑料食品接触材料中丙烯腈在食品模拟物中更容易析出,存在的安全风险更大。

Objective To study the migration of acrylonitrile from acrylonitrile styrene (AS) and acrylo-nitrile butadiene styrene (ABS) plastic food contact materials.Methods The migration of acrylonitrile in dif-ferent kinds of food simulation was determined under different using conditions by the headspace gas chroma-tography, and the inference of food,simulation temperature and time to the migration of acrylonitrile was also studied, and the acrylonitrile monomer residue was compared to the migration of acrylonitrile.Results The migration of acrylonitrile in AS plastic food contact materials was higher than that of ABS plastic food contact materials. Under the same condition, the acrylonitrile migration in 50% ethanol is the biggest among the dif-ferent food simulation. In the same simulating food, the acrylonitrile migration increased with the contacting time and temperature.ConclusionCompared to ABS plastic food contact materials, acrylonitrile in AS plas-tic food contact materials showed an easier migration to the food simulation, which indicated a greater security risk existing in AS plastic food contact materials.
