Abstract: Response surface analysis was used for optimizing the microwave-assisted extraction of chlorophyll from filter mud in sugar cane mill factories. The results showed that the optimal conditions for microwave-assisted extraction of chlorophyll were microwave irradiation time of 60 s, extraction temperature of 34 ℃ and material-to-liquid ratio of 1:7 (g/mL). Under these conditions, the predicted chlorophyll yield was 0.280 mg/g, which was close to the actual chlorophyll yield of 0.277 mg/g. Compared with the traditional extraction, microwave-assisted extraction revealed an enhanced yield of chlorophyll by 6.95% with considerably time-saving benefits.
