초록

식품과 포장재의 상호 작용 정도를 나타내는 분배 계수는 포장재의 구조 및 특성은 물론이고 내용물의 구조적 특성 그 중에서도 결정도 (crystallinity)에 의해서도 많이 좌우되고 있다. 온도의 상승에 따른 식품 성분의 결정도 상실은 내용물과 포장재의 상호 작용 증가를 초래하고 있다. 따라서, 최근 가공 식품 개발의 큰 부분을 차지하고 있는 즉석 식품의 경우 제조시 가열은 물론 소비자에 의해 한번 더 가열된다는 점에서 내용물과 포장재의 상호 작용에 의한 이취 발생 및 식품 안전성에 부정적인 요인이 될 수 있다는 점에서 이에 대한 체계적인 연구가 필요하다고 하겠다.

Migration behavior of printing ink solvents on three types of chocolates with different fat content and fat compositions (different crystallinity) was investigated. Even though chocolate cream (29%) has lower fat content (29%) than that of chips (48%), it showed higher degree of migration. However, with increasing temperature, degree of migration was depended on mainly fat content. This result indicated that degree of migration was mainly affected by crystallinity at below melting point of chocolate, but the effect was diminshed as the temperature was close to melting temperature.
