摘要
模拟超市存放条件,探讨了用筒状透明塑料薄膜包裹的生菜在温度为17±2℃、相对湿度为70%和40W荧光灯照射的贮藏条件下其品质变化。结果表明,用筒状透明塑料薄膜包裹的生菜贮藏期间的呼吸强度、相对电导率均低于未包裹的和散堆的生菜,叶绿素、还原糖含量则高于未包裹的和散堆的生菜,抗坏血酸和失重率介于两者之间。
fresh lettuce were harvested directly from the suburb vegetable production base near Nanjing Agricultural University, cleaned and divided into three groups, then stored at the temperature of 17±2℃, 70% relative humidity and lighted with fluorescent lamp （40W）, The lettuce of group 1 were put into the cylindrical transparent plastic film bags, group 2 directly into plastic basket without package, and group 3 heaped naturally without package. During their storage period, the respiration rate and relative electric conductivity of the lettuce in group 1 were lower, but the contents of chlorophyll and reduced sugar were higher than those of the lettuce in group 2 and group 3, Ascorbic acid content and weight losses of lettuce in group1 were higher than those in group 2, but lower than in group 3,
