Abstract

To extend the shelf-life of kidney bean (Phaseolus vulgaris L.) after harvest, we investigated the effect of packaging material and storage temperature. In case of film package, there was no weight loss during storage, but in paper-box package, remarkable weight loss occurred as storage period extended and storage temperature risen. Firmness of kidney bean was greater in low temperature than ambient temperature storage. Content of vitamin C was decreased rapidly during storage, and in paper package, low temperature storage group had lower decrease of vitamin C than that of room temperature. Total chlorophyll content was not difference among storage temperatures in film package treatments. However, in paper-box package, decrease of chlorophyll in room temperature storage was greater than that of low temperature ($8{\sim}10^{\circ}C$). In terms of freshness of kidney bean, we suggest that shelf-life by low temperature storage ($8{\sim}10^{\circ}C$) after PP film or paper package was 8 days, but that by room temperature storage after paper package was 4 days.

꼬투리째 먹는 채소인 풋꼬투리 강낭콩의 수확후 포장 및 저장 유통온도별 품질보존 및 상품성에 미치는 영향을 조사하였다. 저장중 중량의 변화에서 PP필름 포장시는 변화가 없었으나 골판지박스 포장시는 저장 온도가 높고, 저장기간이 길어질수록 중량 감소율이 현저하였다. 저장중 경도는 저온저장이 상온저장보다 높게 유지되었다. 비타민 C함량은 저장중 모든 처리에서 감소되었고, 그 감소의 폭은 상온저장보다는 저온저장 시 적었다. 엽록소함량은 비닐필름 포장시는 저장온도간에 차이가 없었으나, 박스포장시는 상온저장시 엽록소함량의 감소가 저온저장보다 컸다. 외관 상품성을 표시하는 신선도는 비닐포장이나 골판지박스에 속비닐 넣은 후 산물을 포장하여 $8{\sim}10^{\circ}C$정도에서 저장 유통시는 상품유지기간이 8일 정도로 상온보관대비 4일정도 연장되었다.
