| 摘 要： | 以新鲜菠菜和生菜为试材,使用低温加湿保鲜柜,研究了叶菜类蔬菜低温加湿方式贮藏期间叶片VC含量、失重率和色差值的变化。结果表明:低温加湿方式贮藏叶菜类蔬菜能够较好地保持叶片水分和叶片组织的活性,贮藏5 d后,叶菜中VC含量损失率低于30%,明显低于其他贮藏方式,叶片日均失重率为4%左右,而低温贮藏为10%左右,此外,叶片色差变化最小,很好地保持了蔬菜的新鲜度。

Effect of Low Temperature and Humidification Preservation on Storage Quality of Leaf Vegetables |
| |
| Abstract: | The changes of VC content, weight loss rate and chromatic aberration of leaf vegetables during storage were studied by using low temperature humidifying cabinet with fresh spinach and lettuce as materials. The results showed that the low temperature humidification storage of leaf vegetables could keep the leaf water and leaf tissue activity better. After 5 days of storage, the loss rate of VC in leaf vegetables was less than 30%, which was lower than other storage ways. The average daily weight loss rate of leaves was about 4%, while that of low temperature storage was about 10%. In addition, the change of leaf chromatic aberration was the smallest, which maintained the freshness of vegetables very well. |
