摘要:

研究纸张印刷油墨中4 种增塑剂(3 种邻苯二甲酸酯类增塑剂和近年流行的环保增塑剂乙酰基柠檬酸三丁酯)向食品模拟物Tenax和奶粉的迁移,考察其在110、250、440、600、900 W微波功率下的迁移行为,探讨迁移影响因素,并与常规条件下的迁移行为做比较。结果显示在一定条件下微波功率越高,迁移量越大;且迁移行为受增塑剂的分子质量、极性等性质的影响;常规条件下的迁移影响因素也适用于微波条件。

Abstract:

The migration of plasticizers from the printing inks through packaging paper to Tenax and milk powder was
studied under microwave heating at power levels of 110, 250, 440 W and 900 W, respectively, and for different contact times
ranging from 2 min at 900 W to 15 min at 110 W. The inks were offset printed by simulating the real situation, which has
never been used in migration research. The plasticizers investigated included the commonly used dibutyl phthalate (DBP),
bis(2-ethylhexyl) phthalate (DEHP), di-n-octyl phthalate (DOP) and a new type environmentally-friendly plasticizer, acetyl
tributyl citrate (ATBC). Gas chromatograph coupled with mass spectrometer (GC-MS) was used for the determination of
ethanol extracts of these plasticizers from printed paper, Tenax and milk powder. The results showed that heating power,
contact time and some properties of the compounds were all able to affect their real mass transfer. Migration factors under
the conventional conditions also apply to microwave conditions.
