Abstract

In order to cope with risk issues of overseas on 4,4'-diaminodiphenylmethane (4,4'-MDA) known to used in the production of polyamide resins, we investigated on 4,4'-MDA migration from plastic cooking utensils. 93 samples of plastic cooking utensils were collected from the retail markets in 7 major cities of Korea during March to June, 2007 and 4,4'-MDA levels migrated to food simulants, water, 4% acetic acid, 20% ethanol and n-heptane, on plastic cooking utensils was quantified by liquid chromatography with tandem mass spectrometry (LC-MS/MS). 4,4'-MDA was detected in 14 samples, and the levels of 4,4'-MDA migrated to food simulants were in the range of $0.001{\sim}0.026$ ppm. Among them, the 4,4'-MDA migration amounts of 2 samples were above 0.01 ppm defined by the EU.

4,4'-diaminodiphenylmethane (4,4'-MDA)는 일차방향족아민 (primary aromatic amino, PAA)류의 일종으로, 최근 유럽에서는 RASFF를 통하여 나일론 재질의 주방용 국자, 주걱 등에서 4,4'-MDA 이행 사례를 보고하고 있어 국내 유통 합성수지제 조리기구 중 4,4'-MDA 이행량 실태를 조사하였다. 4,4'-MDA의 분석을 위하여 0.3 ppb의 정량한계 및 87.6% 이상의 우수한 회수율을 나타내는 LCMS/MS를 이용한 분석방법을 확립하였다. 식품유사용매 물, 4% 초산, 20% 에탄을 및 n-헵탄에 대하여 4,4'-MDA 이행여부를 조사한 결과, 4% 초산 및 20% 에탄올인 경우에는 분석대상 100 품목 중 나일론 재질 14 품목에서, 물인 경우에는 나일론 재질 11 품목에서 식품유사용매로 4,4'-MDA가 이행되는 것으로 나타났으나, n-헵탄을 사용한 경우에는 1개 품목에서만 미량의 4,4'-MDA가 이행되었다. 이중 유럽연합 기준인 0.01 ppm을 초과하는 제품은 2품목이었다.
