Comparison of extracted amounts and patterns of microwavable ready-to-meal plastic packaging materials

Increasing use of plastics in food packaging materials has led to the issue of food-plastic packaging materials mutual interactions. Rapid development of new microwavable ready-to-meal products requires suitable plastic packaging materials for safe heating with the contained food. However, data is still required to diminish consumers' safety concern about ready to meal packaging materials. Amounts and patterns of extracted materials from the ready-to-meal packaging materials of Korea and Japan by heat treatments ($120^{\circ}C$ for 30 min.) was investigated and compared by using Gas chromatography. Total peak number of extracted materials from Korea packaging materials was six while that of extracted materials from Japan's was only two. Moreover, the extracted amounts of packaging materials from Korea company was much higher than those of Japan's. Additional research is needed to justify the reason why extracted materials from packaging materials from Korea be much more occurred, and how the amounts from Korea packaging materials can be reduced.
