Optimization of utrasonic-assised extraction process for pigment from castor by response surface extraction

Graphical Abstract

Abstract

Abstract

Response surface methodology was used to optimize the ultrasonic-assisted extraction of pigment from castor with the yield as investigation index. Based on the single-factor tests, the center combination experiment was established with three key factors of ethanol concentration extraction temperature and extraction time. The results showed that the optimal extraction conditions were as follows:94% ethanol concentration, 56℃extraction temperature and 104min extraction time. Under this condition, the extraction rate of pigment from Castor was up to 85.97%.
