Abstract

This study was conducted to find out the effect of vitamin C treatments on the storability of several baby vegetables; endive, green romaine lettuce, pak-choi, red romaine, lollo rosa, and ssamchoo. The vitamin C was treated by the foliar spray which was carried out 3 times before harvest or dipping in vitamin C solution for 5 minutes after harvest. The vitamin C contents of 6 different baby vegetables were higher in vitamin C treatments than control, whereas the difference of vitamin C content between treatments was disappeared after storage. The fresh weight of ssamchoo and lollo rosa lettuce treated by vitamin C was maintained higher than that of control. There was not significant difference in visual quality among treatments, though some of baby vegetables treated by washing with vitamin C showed better visual quality than the others. The contents of carbon dioxide, oxygen and ethylene in MAP with baby vegetables did not show any difference among treatments. As the result, high concentrated vitamin C treatment, such as the foliar spray and washing (dipping) had a role of increasing functionality, but the enhanced functionality, high vitamin C, did not affect storability in baby vegetables.

본 연구는 저장전 비타민 C 처리가 엔디브, 청로레인, 청경채, 적로메인, 롤롤로사, 쌈추의 베이비채소의 저장성에 미치는 영향을 알아보고자 수행하였다. 비타민 C 처리는 수확 전 3차례 실시한 엽면살포와 수확한 베이비 채소의 세척과정에서 5분간 침지하는 두 가지 방법으로 실시하였다. 비타민 세척과 재배중 엽면살포 처리 후 6가지 베이비채소의 비타민 C 함량은 저장전에는 모두 비타민 C 처리구에서 대조구보다 높았으나 저장후 일정한 경향이 없어 모두 저장 전에 비해 감소하였다. 생체중 변화의 경우 6가지 베이비 채소 모두에서 처리간 큰 차이는 없었으나 쌈추와 롤롤로사의 경우 대조구에 비해 비타민 처리구의 생체중 감소가 다소 적었고, 외관상 품질의 경우 비타민 C 침지 처리구에서 일부 효과가 보였으나 대조구와 통계적 유의성은 없었다. 포장내 이산화탄소와 산소농도는 비타민 처리로 인한 큰 변화는 없었으며, 에틸렌 농도 역시 처리간 차이를 나타내지 않았다. 따라서 베이비 채소 재배 중 혹은 세척 중 실시한 비타민 C 처리는 베이비 채소의 기능성의 향상의 효과는 있었으나 저장성 향상에는 큰 영향을 주지 못하였다.
