Abstract

The extraction techniques of purple cabbage pigment from fresh purple cabbage were studied.Identified various factors on the extraction rate of the order ethanol volume fraction : solid-liquid ratio extraction time extractants ratio extraction temperature,The optimal extraction parameters for purple cabbage pigment from fresh purple cabbage were obtained as followed : A1B2C2D2,solid-liquid ratio 1 g∶2 mL;extraction time 4 h;75% ethanol:0.4% acetic acid(volume ratio) 2∶1;extraction temperature 35 ℃,extraction ratio 12.4%.
