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.
