| 摘 要： | 制备了壳聚糖复合膜，并应用于黄瓜保鲜。在保鲜实验中，测定了黄瓜的失水率、叶绿素、维生素C、硬度等指标的变化。结果表明，使用涂膜保鲜后，12d时黄瓜的失水率为7．5％、维生素C减少45．4mg／kg、叶绿素减少5mg／kg，黄瓜的硬度保持较好。利用壳聚糖复合膜的保鲜效果好于通常的保鲜膜保鲜效果。

| Abstract: | Complex chitosan membrane was prepared and its application on the preservation of cucumbers was studied.The results showed that after preservation with chitosan membrane for 12 days,the dehydrating rate was 7.5%,Vitamin C decreased in 45.4 mg/kg,chlorophyll decreased in 5 mg/kg,the hardness was well kept.The composite chitosan membrane showed better preservation results than that of normal film.kwy words:chitosan;composite membrane;preservation;cucumber |
