摘要
采用响应面法优化亚临界萃取金盏花中叶黄素的提取工艺。以富含维生素A原的金盏花为原料,采用亚临界萃取法,通过单因素实验考察金盏花颗粒尺寸、萃取时间、萃取温度对叶黄素萃取量的影响,并在此基础上采用Box-Behnken设计响应面实验优化提取工艺。结果表明,金盏花中叶黄素的最佳提取工艺参数为金盏花颗粒尺寸9 mm、萃取时间48 min、萃取温度40℃,在此条件下亚临界萃取物中叶黄素含量为(31.94±0.22)g/100 g。
The extraction process of lutein fromCalendulaofficinaliswas optimized using response surface methodology.Calendulaofficinalis,which is rich in provitamin A,was used as raw material,and subcritical extraction was employed.The effects of particle size,extraction time,and extraction temperature on lutein yield were investigated through single-factor experiments.Based on this,a Box-Behnken design response surface experiment was conducted to optimize the extraction conditions.The results showed that the optimal extraction parameters for lutein fromCalendulaofficinalis were particle size of 9 mm,extraction time of 48 min,and extraction temperature of 40℃.Under these conditions,the lutein content in the subcritical extract reached(31.94±0.22)g/100 g.
