Abstract: In this study, cellulase was used to extract pigment from chestnut shells. The effects of ethanol concentration, extraction time, extraction temperature, cellulase dosage, material/liquid ratio and pH on extraction rate of pigments were investigated. Based on one-factor-at-a-time experiments, Box-Behnken central composite design was used to optimize the extraction conditions. The results showed that the optimal extraction conditions were pH of 6, cellulase dosage of 0.6%, extraction temperature of 94 ℃, and extraction time of 120 min.

Key words: chestnut shells, pigment, extraction, response surface methodology
