Yanfang Wang

Abstract

The effects of ratio of sample to solvent,temperature,pH value and the extraction yield of purple sweet potato pigment wers studied in the cast that 95% ethanol was taken as extraction solvent in this expreiment.The optimum technollgical condition were obtained which were showed as follows: the extraction was carried out at 60 ℃ for 1 h,the ratio of sample to solvent is 1:5,pH is 4.In addition,the stability of the pigment was also studied.
