Abstract
The migration of alkylphenols from PVC packaging materials (wrap, sheet and gasket) into food simulants and foods were analyzed by reversed-phase high-performance liquid chromatography with fluorescence detection and gas chromatography with mass selective detection. Only seven nonyl phenol isomers were detected in three types of PVC food packaging materials and the content of nonyl phenol of wrap was higher than those of sheet and gasket. The contents of nonyl phenol migrated from fatty food simulants (n-heptane) were higher than those from aqeous food simulants (distilled water, 4% acetic acid and 20% ethanol) and increased with increase in temperature. Nonyl phenol in fruit juice, infant formula, and beverage was migrated from PVC gasket, olefin gasket, and olefin bottle cap, respectively. Nonyl phenol was also detected from foods even before contacting with the packaging materals.
식품포장용 PVC제인 wrap, sheet 및 gasket으로부터 식품 유사용매와 식품으로 이행되는 알킬페놀류를 HPLC와 GC/MSD로 분석하였다. 세 가지 모든 재질에서 7개의 nonyl phenol 이성질체만이 검출되었고 다른 알킬페놀류는 검출되지 않았으며, wrap이 sheet와 gasket보다 그 함량이 높았다. 각 포장재질로부터 수용성 식품유사용매(증류수, 4% acetic acid, 20% ethanol)와 지용성 식품유사용매(n-heptane)에 의한 nonyl phenol의 용출량은 처리온도
