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

摘要: 以蓖麻壳为原料,采用响应面法优化超声提取蓖麻色素工艺。以蓖麻色素提取率为考察指标,在单因素实验的基础上,选取乙醇浓度、提取时间、提取温度三个因素,进行中心组合实验。结果表明,蓖麻色素的最佳提取工艺条件为乙醇浓度94%,提取时间104min,提取温度56℃,此条件下蓖麻色素提取率为85.97%。

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%.
