Abstract

A study of the levels of phthalate and adipate esters, which are suspected as endocrine disruptors, in food packaging wraps and packaged foods were carried out. Among 11 wrap samples, 8 household wraps purchased at retail markets were polyvinyl chloride(PVC) and polyethylene(PE), while 3 commercial wraps at wholesale markets were PVC. All of 51 selected food samples, such as 12 samples of vegetable, 11 samples of fruit, 6 samples of bread and rice cake, 4 samples of meat and poultry, 4 samples of fish and 14 samples of side dish, packaged with commercial PVC wraps containing adipate esters were purchased at retail markets. The level of di-(2-ethylhexyl) adipate(DEHA) and diisononyl adipate(DINA) was from 2.2 to 17.9% and from 4.2 to 22.3% in household PVC wraps, respectively. In the commercial PVC wraps, the level of DEHA showed from 18.3 to 22.5%, while other phthalate esters were not detected. The phthalate and adipate esters were not detected in PE wraps. The level of DEHA in packaged foods, such as vegetable, fruit, bread and rice cake, meat and poultry, fish and side dish, were determined up to $8.2\;{\mu}g/cm^2,\;17.4\;{\mu}g/cm^2,\;31.0{\mu}g/cm^2,\;8.3\;{\mu}g/cm^2,\;2.1\;{\mu}g/cm^2$ and $92.3\;{\mu}g/cm^2$, respectively. The results suggested that migration levels of DEHA in foods were closely related to the fat content, wrapping condition of food and stroage time and temperature.

Wrap으로 포장된 식품에서 내분비계장애추정물질인 phthalate 및 adipate esters를 조사 하였다. 총 11개의 wrap 시료중 재질이 polyvinyl chloride(PVC) 및 polyethylene(PE)인 8종의 가정용 wrap과 PVC 재질인 3종의 업소용 wrap을 각각 소매점과 도매점에서 입수하였다. Wrap로 포장된 식품은 야채류 12종, 과일류 11종, 빵 및 떡류 6종, 육류 및 가금류 4종, 어류 4종 및 가공식품 및 반찬류 14종 등 총 51종으로 소매점에서 입수하였다. PE wrap에서는 phthalate 및 adipate esters가 검출되지 않았고 PVC wrap에서는 모두 adipate esters가 사용 되었으며 di-(2-ethylhexyl) adipate(DEHA)만 사용된 경우와 DEHA 및 diisononyl adipate(DINA)가 혼합된 경우가 있었다. 가정용 PVC wrap에서 DEHA만 사용된 경우는 각각 15.8, 17.9%만 검출 되었으며 DINA가 혼합된 경우는 DEHA 3.6, 2.2%에 대해 각각 DINA가 22.3, 4.2% 검출되었다. DEHA가 포함된 업소용 wrap으로 포장된 식품에 대하여 야채류는 검출한계 이하에서 $8.2\;{\mu}g/cm^2$까지, 과일류는 $17.4\;{\mu}g/cm^2$까지, 빵 및 떡류는 $31.0\;{\mu}g/cm^2$까지, 육류는 0.3에서 $8.3\;{\mu}g/cm^2$까지, 어류는 $2.1\;{\mu}g/cm^2$까지, 가공식품 및 반찬류는 0.1에서 $92.3\;{\mu}g/cm^2$까지 나타내었다. 군별로 비교할 때 튀김 등 가공식품 및 반찬 류에서의 검출량이 야채류, 육류, 어류 등에 비해 월등히 높았으며 과일류, 빵 및 떡류에서 중간 수준을 보여 전반적으로 지방 함량에 비례하는 경향을 보였다.
