Abstract：In this paper， Xinyang Chestnut was used as raw material to extract shell pigment， and the extraction process was optimized on the basis of single factor. The results show that the optimum extraction parameters of chestnut shell pigment is the ratio of material to liquid 1∶19 （g/mL）， extraction time is 2.1 h， extraction temperature is at 71 ℃. Under this process， the extraction rate of pigment was 4.35%. The significant order of the three factors selected in the experiment are as follows： ratio of material to liquid > extraction time > extraction temperature.

Keywords： response surface method; chestnut shell pigment; process optimization
