为研究纳米包装纸和保鲜膜结合对迷你黄瓜的保鲜效果，试制了不同浓度的TiO-2涂膜纸，并与保鲜膜结合包装保鲜迷你黄瓜，观察了贮藏过程中迷你黄瓜的感官品质变化，并测定了迷你黄瓜的失重率、硬度、维生素C含量、叶绿素含量。实验结果表明，纳米TiO-2保鲜纸结合保鲜膜包装迷你黄瓜可有效延长其货架期，15%（体积分数）的纳米涂膜纸与保鲜膜结合，可使迷你黄瓜的保质期延长到30 d以上。

Nano-TiO-2 coated paper of different TiO-2 concentration was prepared and used together with preservative film for fresh-keeping of mini cucumber. The sensory quality of mini cucumber was evaluated during storage process. The weight loss, hardness, vitamin C contents and chlorophyll content of mini cucumber were determined. The results showed that the shelf life of mini cucumbers can be extended by packaging with preservative film combining fresh-keeping film; 15% nano-TiO-2 coated paper combining fresh-keeping film can extend shelf life of mini cucumber by 30 days.
