[Objective] To study the optimal extraction process of the pigment from papermulberry peach fruit.[Method] Through the single factor tests,the most suitable solvent and the best determination wavelength and pH were screened;effects of solid-liquid ratio,extraction temperature and time on pigment extraction results were aslo studied.On the basis of single factor tests,the orthogonal test was adopted to optimize the technological parameters.[Result] Single factor tests results showed that the most suitable so...
