Abstract

The migration potential of volatile organic solvents widely employed in the printing process of food packaging was investigated by using a closed experimental system, which contained a food sample and a paper sheet spiked with the contaminant solvents. The studied organic compounds included toluene and p,m,o-xylene which are relatively highly volatile. Typical food samples of caramel, beef jerky and butter were selected based on their chemical composition and were assigned to the migration system at 10, 25 and 4$0^{\circ}C$. The equilibrated migration level was very high with almost complete transfer in the butter with high fat, while caramel of high carbohydrate content and beef jerky of high protein showed migration degree of 37∼56% and 37∼77%, respectively. Temperature did significantly influence the migration on beef jerky with higher level at higher temperature. There was no difference in the migration level among the solvents.

포장재에 잔존하는 인쇄 관련 유기용매가 식품으로 포장공간을 통하여 이행되는 가능성을 평가하기 위하여, 식품포장을 모사한 이행실험 시스템을 구성하여 이행가능오염 물질의 기체를 통한 식품으로의 이행량을 측정하였다. 포장식품에서 잠재적인 오염물질 중 인쇄와 관련한 유기 용매 중 비교적 휘발성이 높은 toluene p,m,o-xylene 등을 종이 포장재에 오염시키고, 이를 식품시료와 함께 밀폐 용기내에 두고, 이들 유기용매가 얼마나 식품으로 이행되는지를 측정하였다. 대표적 식품으로서 식품성분특성에 따라 당질, 단백질, 지방이 주 구성성분인 식품으로서 카라멜, 우육포, 버터를 선정하여 10, 25, 4$0^{\circ}C$의 조건에 평형상태의 이행정도를 측정하였다. 휘발성 유기 용매의 이행은 지방성 식품에서 아주 높게 이루어졌으며, 당질 식품인 카라멜의 경우 실험온도의 범위에서 37∼56%의 행율을 보였고, 단백질 함량이 높은 우육포에서는 37∼77%의 이행률을 나타내었다. 온도의 영향은 우육포에서만 유의하게 나타났으며, 이 경우 고온에서 높은 이행비율을 보였다. 용매 종류에 따라서는 이행정도에 차이를 보이지는 않았다.
