中文摘要:

为研究壳聚糖/明胶/单甘酯复合涂膜联合气调对果菜保鲜效果的影响，选择迷你黄瓜为试材，实验了单一气调和联合技术对迷你黄瓜失重率、呼吸强度、冷害指数、丙二醛含量、细胞膜渗透率、抗坏血酸含量以及水分状态指标的影响。结果表明，壳聚糖复合涂膜联合气调保鲜技术显著优于单一的气调保鲜技术，可有效保持果实品质，减少冷害现象的发生，在8 ℃下可保鲜迷你黄瓜至25 d。

英文摘要:

In order to study the effect of chitosan / gelatin / monoglyceride composite coatings on the freshness of fruits and vegetables. Chose mini-cucumbers as test material. Researched the effects of MAP and combined technique on weight loss，respiration rate，chilling injury index，MDA content，cell membrane permeability，Vc content and water status of mini-cucumbers. The results showed that chitosan composite coatings combined with modified atmosphere preservation technology was superior to single atmosphere preservation technology，which promoted the quality of vegetables and reduced the occurrence of chilling injury，and extend the shelf life to 25 days at 8 ℃.
