Abstract

Packaging is the last defensive barrier that protects food products from insect infestation during storage. However, though packaging films are hermetically sealed, insects can still be attracted by strong olfactory cues and penetrate through packaging materials, resulting in contamination. Insect contamination may cause consumers to be repulsed by contaminated food products. Especially, it is well known that stored-product insects cause critical problems in the cereal industry by inducing quantitative and qualitative damages to the grain products. The contaminations are caused by insects' metabolic byproducts and body parts, consequentially caused customer repulsion. Therefore, it is necessary to repel and control insects. However, management systems for storage insects in food industry have been inadequate for many years. Synthetic pesticides has been widely used, but pesticides may accumulate in foods, causing acute and chronic symptoms in consumers. For this reason, there is a growing need for the development of natural insecticides that can replace synthetic pesticides. Thus, various reports about anti-insect packaging materials and strategies to repel insects were introduced in this study. Furthermore, we suggested new strategies to develop an insect-repelling active packaging materials which could be applied in the food packaging industry.

소비자들의 전반적인 생활환경 향상에 따른 웰빙 라이프 추구에 따라 소비자는 맛뿐만 아니라 식품의 질적인 측면 또한 중요시하게 되었으며, 이에 따라 안전한 식품 섭취에 대한 요구가 확대되었다. 또한 가공 곡류 등의 저장 식품에서의 해충의 피해가 빈번히 일어나며, 이는 식중독 유발 등 인체에 위해를 가할 수 있다는 보고가 계속 됨에 따라 이에 대한 해결 방안이 필요하다는 목소리가 커지고 있는 실정이다. 따라서 전 세계적으로 식품에의 해충 오염 원인을 파악하고 이에 대한 해결 방안을 제시하기 위한 연구들이 지속적으로 진행되고 있으나 궁극적인 해결 방안이 제시되지 않고 있는 실정이며, 특히 방충 식품 포장재 개발 연구에 뒤따른 실질적인 상용화는 상당히 미흡한 실정이다. 따라서 식품 업계에서는 식품포장 본연의 목적을 충실히 만족하며 기능성 포장으로서 해충의 침입을 방지하는 합리적인 방충 포장재 개발기술을 발전시키는데에 총력을 기울여야 할 것이다. 더불어 앞으로 산학연의 협력하에 저장해충을 방지할 수 있는 안전성이 입증된 적합한 방충 물질 탐색에 관한 연구는 물론, 실제 산업에도 도입시킬 수 있도록 경제성을 갖춘 포장재 개발에 대한 연구가 활발히 이루어져야 할 것이다.
