Title: Study on Ultrasonic Extraction Red Pigment of Eggplant Peel
Abstract: Single factors included solvent, ratio of material to solvent, temperature, extraction time and orthogonal tests were adopted to optimize the extraction process. The results showed that the optimal conditions for the extraction by 90% ethanol as solvent were obtained as follows: the ratio of material to solvent 1∶6 at 70 ℃ for 30 min. Primaries influence of factors was in turn: ratio of solid to solvent is more than extraction temperature more than extraction time.
