Study on Extraction Technology and Basic Properties of Passiflora Edulis Skin Pigment
To enhance the comprehensive utilization value of Passiflora edulis skin,extraction technology of Passiflora edulis skin pigment (PESP) was studied in this paper.Solvent extraction method was used to extract PESP.Among the uniform experimental design,86％ aqueous ethanol containing 0.054％ HCl and 0.1％ citric acid was the best extraction solvent.Through the design of quadratic rotational combination test and multiple regression analysis,the regression model related to extraction yield of PESP indicated that the optimized condition of the response surface model (RSM) was adjusted as 31 ℃,120 min,1:36 to practical production.Under this condition,the extraction rate of PESP was 13.7236％.
