Abstract: The optimal processing data of kiwifruit were derived based on the loss ratios of VC and chlorophyll and freeze-drying time. They were: the highest temperature of the pulp surface 48℃, air pressure of the chamber 26Pa and thickness of pulp7mm. Under these conditions, the loss ratios of VC and chlorophyll were about 6% and 38%, respectively freeze-drying time wasabout 18h.

Key words: kiwifruit, freeze-drying, optimal processing, VC, chlorophyll
