초록

본 총론은 주로 더운 여름에 집중 출하되고 있는 국내 참외에 대한 소비 판매 증대를 위한 품질개선을 위한 수확 후 관리 기술 및 포장재 적용 현황을 고찰하였다. 최근 재배 생산, 유통, 판매 측면에서 고품질 참외 상품화를 위한 수확 후 선별, 예냉, 저장, 유통, 포장 등 다양한 전처리 과정을 통한 과실 품질의 많은 향상을 보이고 있다. 참외 저장은 품종에 따라 다르겠지만 일반적으로 90-95% 상대습도에 7-$10^{\circ}C$ 온도의 저온 조건이 적당하며, 수확된 참외의 고품질 유지를 위하여 저온 장해를 받는 온도 조건에서 보관해서는 안 된다. 수확 후 에틸렌의 발생을 억제를 위한 1-MCP 처리, 활성물질을 가지는 기능성 포장재, 참외의 호흡률을 고려한 CA저장 및 MA 포장은 2-3% 산소 및 5-10% 이산화탄소 조건이 참외의 적정 저장 조건으로 볼 수 있다. 이러한 수확 후 관리 처리 기술의 적용 등은 참외 품질 유지와 저장 기간을 늘일 수 있을 것으로 기대되며, 특히 유통 및 저장에서 취급 중 발생할 수 있는 상품성 저하에 대해 효과적이며 안정적으로 적용할 수 있다. 현재 고품질 참외 제품에 대한 다양한 첨단 선도유지 처리 기술이 연구 진행되고 있지만 품종, 수확시기, 그리고 판매 환경조건 등을 고려한 연구가 필요하며, 국내 참외의 국제 경쟁력을 가지기 위하여 해외 제품과의 브랜드 차별화를 위한 전략적인 연구가 지속적으로 필요하다고 판단된다.

Oriental melon ($Cucumis$ $melo$ var. $makuwa$) is a popular and high-value market fruit cultivated in Korea. Consumers are becoming increasingly interested in oriental melon as a healthy diet over the past few years. However, the melons have relatively high quality loss because the fruit are mainly produced for a limited period of time in the summer season. Lack of the proper postharvest treatments and high temperature exposure at harvest or during distribution are the most critical environmental factors limiting postharvest life of fruit. This review focuses on the overview of current research studies for postharvest treatment and functional packaging technology of oriental melon in Korea. Major physiological problems of the harvest fruit include the ripening process in quality changes of the produce such as loss of weight, firmness, flavor, and decay during the storage periods. Low temperature at 7 to $10^{\circ}C$ with high relative humidity of 90 to 95% is the suitable environmental condition used to maintain the quality of fresh oriental melon. Controlled atmosphere (CA) storage or modified atmosphere (MA) packaging can be used as supplemental treatments to extend postharvest-life. For oriental melon, an optimum CA is currently recommended to be 2-3% oxygen and 5-10% carbon dioxide atmosphere. Precooling, pretreatments of ethylene action and functional packaging system can be applied to oriental melon after harvest in order to extend storage life. Major active packaging technologies are concerned with a selectively gas permeable film related to respiration of produce and the packaging applications of ethylene removal, antimicrobial, and antifogging substances to keep the effective freshness of fruit.
