상추를 포장하여 품종('적치마', '청치마', '적축면', '청축면')과 저장온도(0, 8, 16 및 )에 따른 저장성을 구명하고자 중량 감소율, 호흡률, 선도, 색소함량 및 색상차 등을 조사하였다. 저장온도 조건에 따라 품종별 차이를 달리 보여, 저온()에서는 중량감소 정도 및 선도, 호흡률 등에 의한 품종별 차이가 크지 않았으나, 저장 온도가 높아지면서 변화 정도와 차이가 커졌다. 중량감소 및 선도 변화에 있어서는 저온 저장 온도인 에서는 3
Shelf-life and quality changes of four leaf lettuce cultivars packaged and stored at four different temperatures (0, 8, 16 and ) were evaluated. Leaf lettuces were packaged in non-perforated polypropylene film (thickness 0.05 mm) bags. Weight loss, respiration rate, freshness degree, pigment content, and surface color were determined. At the storage temperature of , the weight loss, degree of freshness, pigment content, and change of surface color on packaged leaf lettuces showed no significant difference when compared with all other leaf lettuces. Meanwhile, an increase in storage temperature was observed with the quality changes of each flesh leaf lettuce. The leaf lettuces under storage conditions at showed a difference in weight loss of the different types of leaf lettuces during a short storage period. However, there was no clear tendency in weight loss in different types of leaf lettuces as compared with each storage temperature. The rate of respiration and the contents of pigments in the four types of leaf lettuces also showed significant difference as the storage temperature increased.
