中文摘要：

目的 研究常温贮藏条件下PVA活性包装膜对圣女果的保鲜性能。方法 采用3种不同的包装膜（PE膜、PVA包装膜、PVA活性包装膜）对圣女果进行保鲜包装，通过对圣女果的感官评价，同时测定其失重率、腐败率、维生素C及总糖含量等各项指标的变化，比较3种不同包装膜对圣女果的保鲜效果。结果3种包装膜均适用于圣女果的保鲜包装，可延长其货架寿命；通过对保鲜后圣女果各项性能指标进行检测．发现PVA活性包装膜能够更好地延缓圣女果的腐败，降低变质率，维持较高的维生素C及总糖含量．延长圣女果的保鲜期。结论PVA活性包装膜将圣女果的保鲜期延长了6 d以上．达到了很好的保鲜效果。

英文摘要：

Objective To study the fresh-keeping performance of active polyvinyl alcohol packaging film for Cherry Toma- toes. Methods Three different films, the PE films, the PVA packaging films and the PVA active packaging films, were used to pack the cherry tomatoes. Sensory evaluation and determination of variations in weight loss, rotting rate, vitamin C content and total sugar content of cherry tomatoes were used to compare the fresh-keeping effects of the three different packaging films. Results The observation results indicated that all three kinds of packing films were suitable for packing cherry tomatoes and could extend the shelf life. The comparison of the indicators of cherry tomatoes packed by three different films suggested that PVA active packaging film was better in delaying the rotting of cherry tomatoes , decreasing the rate of deterioration, maintaining a high content of vitamin C and total sugar, and prolonging the shelf life. Conclusion Active polyvinyl alcohol packaging film could prolong the fresh-keeping period of cherry Tomatoes by six days, and has achieved very good preservation effect.
