响应面分析溪蜜柚果皮中柚皮苷的醇提取工艺

Optimization of extraction techniques of naringin from pomelo peel by response surface methodology

摘要: 为了有效利用废弃物柚子果皮,提高柚皮中柚皮苷的提取效率,利用响应面分析法对醇溶液提取工艺条件优化。最适合工艺条件:液料比25∶1(m L/g)、乙醇浓度77%、提取时间57 min、提取温度60℃,在此工艺条件下进行实验,柚皮苷得率为5.83%,与理论预测值仅相差0.24%,验证了数学模型的有效性。

Abstract: In order to make effective use of waste pomelo peel and improve the efficiency of extraction of naringin,response surface analysis method was used to optimize the extraction process of alcohol solution. The most suitable process conditions were liquid/solid ratio of 25 ∶ 1( m L/g),ethanol concentration of 77%( v/v),extraction time of 57 min,extraction temperature of 60 ℃.Under this condition,the extraction rate of naringin was 5.83%.The validity of the mathematical model was verified with the theoretical prediction value of 0.24%.
