摘要:

对二苯甲酮和1-羟基环己基苯基甲酮在高温条件下从食品包装纸(白卡纸和牛皮纸)向脂肪类模拟物Tenax以及全脂奶粉中的迁移规律进行研究。为避开奶粉中杂质色谱峰的干扰,气相色谱的升温条件为柱温:80 ℃保留3 min,温度以20 ℃/min 的速率升到150 ℃,保留10 min,然后再以30 ℃/min 升到290 ℃保留10 min。结果表明:温度越高,光引发剂向食品的迁移率就越高,且迁移速率也越大,达到平衡的时间也越短。纸张本身对脂肪的渗透能力是影响污染物迁移的重要影响因素,在高温下包装含脂量较高的食品时,应尽量避免选用脂肪渗透能力较强的纸张。光引发剂由同种纸质食品包装材料分别向Tenax和全脂奶粉迁移的研究表明,光引发剂向奶粉迁移的迁出率较高,奶粉作为一种真实的食品,有很好的吸附能力,因而适合用于做迁移研究,且奶粉成分复杂,更能代表真实食品的特性。

Abstract:

The migration of benzophenone (BP) and 1-hydroxycyclohexyl phenyl ketone (HCH) from food wrapper tomilk powder and Tenax at different high temperatures was investigated. To avoid the interference of unwanted peaks frommilk powder, gas chromatography was carried out under the following conditions: the initial column temperature was 80 ℃for 3 min, increased to 150 ℃ at 20 ℃/min, held for 10 min, and then to 290 ℃ at 30 ℃/min, held for 10 min. As thetemperature increased, larger amounts of BP and HCH were migrated faster and the time required to reach the equilibriumbecame shorter. The infiltration capacity of the food wrapper had an important impact on the migration. The use of paperwith stronger infiltration capacity should be avoided for the high-fat food packaged under high temperature conditions.Compared with Tenax, whole milk powder, which showed better adsorption capacity and more complex composition, wasmore suitable for the migration study.
