Abstract

Packaging bags and corrugated boxes prepared from newly developed antimicrobial packaging paper had greater ability to prolong freshness of packed fruits, and lower weight loss of fruits and microbial growth than non-treated bags and boxes. Addition of zeolite to paper greatly increased absorbance of aging hormone, $C_{2}H_{4}$, emitted from stored fruits, and contributed to decrease in putrefied fruits during storage. Water repellent agent such as alkyl ketone dimer played significant role in preventing functional paper from absorbing water from stored fruits, leading to preservation of fresh weight in stored fruits. Because rise in production cost of functional packaging paper could be offset by reduction of fruit and vegetable wastes, storing fruits and vegetables in functional paper containers was more economical than storing in non-treated containers.

개발된 항균 포장 원지를 이용하여 포장 봉지(packaging bag)와 골판지 포장 상자(corrugated box)를 제작하였고, 여기에 과채류를 포장하였을 때 일반 포장 봉지나 골판지 상자에서 포장된 과채류 보다 변패 미생물의 발생이나 생체중 감소가 상당히 줄어들었다. 이는 BAAG에 의해 과채류의 변패에 관여하는 미생물의 생육을 차단하였고, 제올라이트에 의해 과채류의 조직을 빠르게 연화시키는 기체들인 에틸렌가스, 이산화탄소 및 산소가 제거되었으며, AKD에 의해 과채류가 보유한 수분 손실을 최소한으로 일어나게 하였기 때문이다. 결론적으로 BAAG, 제올라이트, 그리고 AKD로 처리된 포장 원지를 이용하여 제작한 포장대(packaging bag)과 골판지 포장 상자는 저장 과채류의 선도를 유지하는 데 탁월한 효과를 발휘하였고, 기능성 첨가제의 처리로 인한 제조 원가의 상승은 폐기 과채류의 양이 감소하면서 상쇄시킬 수 있었다. 따라서 일반 골판지 상자에 저장된 과채류보다는 기능성 골판지 상자에 저장하는 방법이 보다 경제적인 저장 방법이 될 수 있음을 확인하였다.
