摘要: 采用高效液相色谱法(HPLC)对微波100 w、250 w、440 w与600 w条件下二苯甲酮(BP)和1-羟基环己基苯基甲酮(HCH)从微波纸向脂肪类模拟物Tenax中的迁移规律进行了研究。在此基础上,为了更好地研究微波加热方式对迁移的影响,将微波加热的迁移结果与常用恒温迁移实验方法的结果进行了比较。实验结果得到,BP在250 w和440 w时的最大迁移率几乎相同,而HCH在440 w和600 w时最大迁移率几乎相同,且微波条件下的最大迁移率小于常用恒温条件下的最大迁移率。从实验结果中可以分析出微波条件下,除了功率的作用,温度和功对BP和HCH的迁移也有影响,且相比常用恒温加热的迁移实验,微波加热能加快BP和HCH在脂肪类物质中迁移行为的发生,但最大迁移率降低。

Abstract: The migration of two UV absorbents namely benzophenone (BP) and 1-hydroxycyclohexyl phenyl ketone (HCH) from microwave paper to Tenax in microwave oven at the heating power of 100 w, 250 w, 440 w and 600 w was investigated respectively by high performance liquid chromatography(HPLC). In order to study the influence of different heating modes, the migration was also conducted under constant temperature heating. The results showed that the maximum migration of BP at the heating power of 250 w and 440 w is approximate and that of HCH at the heating power of 440 w and 600 w is approximate. In addition, the maximum migration rate of microwave heating was lower than that of constant temperature heating. We can know that temperature and work were also affected on migration under microwave heating in addition to heating power. And microwave heating can better promote the migration of these two compounds, but the maximum migration rate of microwave heating was lower than that of constant temperature heating.
