Purple sweet potato pigment is a natural food pigment with bright color and multiplies biological functions such as antioxidant activity etc. There is a large amount of unused pigment in the vinasse of purple sweet potato wine. Therefore, in this study, the extraction processes of purple sweet potato pigment from purple sweet potato wine vinasse, as well as its purification conditions were investigated. As the results, 0.9% citric acid-95% ethanol (2/3, v/v) was a suitable extraction solvent to obtain the higher yield of purple sweet potato pigment from vinasse. AB-8 column chromatography showed that the loading ratio of 1/10 (w/v) of resin and pigment with the solvent of 40% ethanol at the flow rate of 2 mL/min were the optimal conditions for the purification of purple sweet potato pigment.
