摘要 本文基于超高效液相色谱建立了一种脂肪食品模拟物异辛烷中抗氧化剂叔丁基对羟基茴香醚(BHA)、2,6-二叔丁基对甲酚(BHT)、四[甲基-β-(3,5-二叔丁基-4-羟基苯基)丙酸酯]季戊四醇酯(Irganox1010)以及β-(4-羟基-3,5-二叔丁基苯基)丙酸正十八酯(Irganox1076)的提取检测方法,加标回收率在78.0%~108.7%之间,相对标准偏差(RSD)在4.0%~13.7%之间。研究了聚乙烯(PE)膜中抗氧化剂向异辛烷的迁移,讨论了温度及时间对迁移的影响,并根据迁移数据进行了初步的数学模型的建立,对实验值与数值模拟结果计算值作了对比分析。 A rapid method based on ultra performance liquid chromatography(UPLC)has been developed for the determination of four antioxidants in fatty food stimulant(isooctane).Recoveries ranged from 78.0%to 108.7%and RSDs ranged from 4.0%to 13.7%.The developed procedure has been applied to determining the migration of the four antioxidants from polyolefins into isooctane under different temperatures.Mathematical modelling based on the data has been established,and the comparison was made between experimental and numerical results.
