| Abstract: | In order to boost the security of the extraction of natural black pigment in walnut flower and improve the extracting ratio,the technical process and conditions of the successive extracting method with solvent are studied.Based on the single factor standard experiment and three-factor doubled standard orthogonal experiment,the optimized conditions of extracting black pigment is set as the followings: with a one-scale extraction,the ratio of is 1:150,the extracting time is 1.5h,the extracting rate can add up to 28.96%,the color valeur is 48.08.This method is safe and reliable. |
