摘　　要：将市售的微波爆米花包装袋用微波感受材料浸入模拟食品玉米油中,在模拟微波条件下加热提取非挥发性紫外可吸收物质。迁移进玉米油中的非挥发性紫外可吸收物质经正己烷-乙腈萃取、浓缩、N,N-二甲基乙酰胺定容至2 mL后,以高效液相色谱分离并定量。结果表明,4个样品的迁移量平均值分别为93.3、134.1、38.4和11.8μg/in2,仅1个样品的迁移量符合美国食品药品监督管理局(FDA)规定的≤20μg/in2的限量标准。In this paper, microwave susceptors in the microwave popcorn bags were immergecl into corn oil. When the system was heated in a microwave oven, some nonvolatile ultraviolet absorbing species were migrated into the corn oil. Such nonvolatile ultraviolet absorbing species were then extracted by hexane-acetonitrile. With water bath and a gentle nitrogen stream, the extract was dried and concentrated, and subsequently kept as a solution of dimethylacetamide of 2 mL. The extract was finally separated with a high performance liquid chromatography and weighed. The weights of the extracts for four samples were 93. 3, 134. 1, 38. 4 and 11.8μg/in2, respectively. Only one of these samples was below the FDA＇s safety limit standard of 20/μg/in2.
