Abstract

This study was conducted to find out the influence of cultivation season for fresh parsley in modified atmosphere storage. As the qualities of fresh parsley grown in different seasons; autumn, winter, summer were compared, the chlorophyll and vitamin C showed the highest content in autumn and winter cultivation, respectively, but the firmness was the highest in summer cultivation treatment. These fresh parsleys grown in different seasons packaged with 0.04mm ceramic film and stored at $0^{\circ}C$. The shelf life of these parsleys were 84 days in winter cultivation treatment, while parsleys cultivated in autumn and summer were able to be stored for 77 days and 56 days, respectively. The fresh weight loss of parsley was much more higher in summer than in both autumn and winter cultivation treatments. The carbon dioxide and ethylene contents in packages in summer were more than twice as high in autumn and winter cultivation treatment. There were not different between autumn and winter cultivation treatment in the two kinds of gas contents. This result should be caused by higher field heat that increased a respiration remarkably during the early storage. The highest field heat produced by summer cultivation resulted in remarkable decreases of firmness, chlorophyll and vitamin C during MA storage. As the results, the fresh parsley showed highest storability in winter cultivation treatment. The field heat of fresh parsley should be eliminated just after harvest for a long term storage.

파슬리의 재배시기별 MA 저장성을 비교하였는데, 먼저 수확 당시 파슬리의 품질을 보면 엽록소 함량은 여름재배, 비타민 C 함량은 가을재배에서 그리고 경도는 겨울재배에서 가장 높게 나타났다. 각각 가을, 겨울 여름에 재배한 파슬리를 0.04mm세라믹 필름으로 포장하여 0$0^{\circ}C$에서 저장한 결과 겨울재배 처리구가 84일간 저장이 가능하였고 다음으로 가을재배가 77일, 여름재배는 56일로 가장 짝은 저장기간을 보였다. 생체중 감소는 여름재배 처리구에서 가장 컸다. 포장내 이산화탄소와 에틸렌 농도는 가을과 겨울에 재배한 처리구는 낮았고 서로 유사한 경향을 보였으나 여름재배 처리구는 수확 당시 높은 포장열과 이로 인한 저장 중 높은 호흡으로 이보다 $2{\sim}3$배 높았다. 이러한 결과는 여름재배 처리구가 가을과 겨울에 재배한 처리구에 비해 경도, 엽록소, 비타민 C함량 등의 품질이 단기간 내에 현저히 감소를 초래하였다. 이상의 결과로 보면 수확시기별로 겨울에 수확한 파슬리의 저장성이 가장 우수하였고 파슬리 MA저장시 장기저장을 위해서는 수확직후 포장열 제거가 매우 중요하다는 것을 알 수 있었다.
