| 中文摘要: |
| 目的 延长油菜贮藏保鲜期。 方法 以油菜为试材，以聚乙烯(PE)为包装薄膜，研究在 5 种不同体积分数的气体配比下油菜各项生理生化指标变化。 结果 在 4 ℃下，初始气体 O2， CO2， N2的体积分数为 5%， 8%， 87%时，可有效抑制 POD 和 PPO 活性，电导率上升，降低呼吸强度、失重率、维生素 C 的损失，减缓叶绿素的降解，贮藏时间可延长至 35 d，具有良好保鲜效果。 |
| 英文摘要: |
| This work aimed to prolong the preservation time of Brassica campestris L. The effect of five different proportional gas concentrations on physiological and biochemical changes of Brassica campestris L at 4 ℃ were investigated using PE as packaging materials in this paper. The results showed that the treatment with O2 5%, CO2 8%, N2 87% could effectively inhibit the activity of peroxidase (POD ) and polyphenol oxidase (PPO), enhance the conductivity, and decrease respiration rate, weight loss rate, loss of vitamin C and degradation of chlorophyll. The preservation time was extended to 35 days and it had a better preservation effect. |
