Abstract

The principal objective of this study was to develop a method to prolong the freshness and maintain the quality of muskmelon (Cucumis melo L.) treated with 1-methylcyclopropene (1-MCP). The rate of weight loss increased with storage time for all samples, but the rates were lower in the 1-MCP treated samples than in the control samples. The hardness of muskmelons treated with 1-MCP differed significantly from that of the controls. The soluble solid contents in the control were highest on day 4 at 15.1%, and evidenced a decreasing trend as the storage period elapsed. Conversely, the soluble solid contents of the 1-MCP-treated samples remained steady at 14% until day 16. The acidity of 1-MCP-treated samples was higher than that of the control over 10 days of storage. The respiration rate of the 1-MCP-treated samples increased less and was lower than that of the controls. Based on the results of our sensory evaluation, muskmelon treated with 1-MCP gas remained fresh for more than 25 days, whereas the control samples remained fresh for only 13 days.

본 연구에서는 멜론과실의 품질유지 및 저장성 향상을 위하여 1-MCP의 실용화 방법을 모색하고자 수행되었다. 모든 시료에서 저장기간이 지날수록 감모율이 증가하는 경향을 보였으나 동일한 저장일에는 무처리구가 1-MCP 처리구보다 항상 높게 나타났다. 경도변화에서 무처리구는 저장 1일 이후부터 급속히 감소된 반면 1-MCP 처리구는 7일 이후에 감소되었으며 무처리구에 비해 감소폭도 적었다. 가용성고형물 함량은 무처리구의 경우 저장 4일에 15.1%로 가장 높은 값을 보인 후 저장기간이 경과될수록 감소되는 경향을 보였으나 1-MCP 처리구는 저장 16일까지 14% 내외로 일정하게 유지되는 경향을 나타내었다. 산도는 무처리구의 경우 저장 10일 이후부터 감소되어 저장 25일에는 0.2%로 현저하게 낮은 값을 보였으나 1-MCP 처리구는 22일 이후부터 감소하여 산도가 일정하게 유지되는 경향을 나타내었다. 관능검사 결과 무처리구는 저장 13일 이후부터 멜론의 맛과 풍미가 유의적으로 감소되었지만 1-MCP 처리구는 25일까지 맛과 풍미가 유지되었다(p<0.05). 전체 기호도는 5점을 marketable의 한계점으로 두었을 때 1-MCP 처리구가 무처리구보다 지수도 높았고 선도도 오래 유지되었다.
