| Abstract: | Purple sweet potato pigment can be utilized in production.To provide theoretical base for the use of purple sweet potato pigment,the pigment extraction conditions are studied with purple sweet potato as raw material,alcohol and organic acid as solvent.The effects of extracting liquid concentration,the material-to-liquid ratio,extracting times,and extraction period are detected.With single factor experiment and orthogonal test,the optimal extracting conditions are set as the following:the soaking time of pur... |
