摘要
采用响应面法对超声波辅助提取荆芥中维生素C的工艺进行研究.根据单因素试验结果,利用Central Composite Design原理进行响应面设计并进行优化.结果显示:当乙醇体积分数为70％,液料比为30∶1(mL/g),超声温度为60℃,超声时间为30 min时,维生素C提取率24.39 mg/g,为最佳提取条件,而模型预测维生素C提取率为24.46 mg/g,理论预测值与试验结果接近,说明该响应面模型有效可靠,为进一步开发利用香菜资源提供技术依据.
Abstract
This paper studied the optimization technique of ultrasound-assisted extraction of catnip vitamin C by response surface methodology.According to single factor experimental results,the experiment was designed and optimized using the Central Composite Design.The results showed the optimal extraction condition was ethanol concentration 70％,the liquid material ratio 30∶1(mL/g),ultrasonic temperature 60 ℃,and ultrasonic time 30 min.Under the condition,the vitamin C extraction yield was 24.39 mg/g,and it was close with the value predicted from the theoretical model which was 24.46 mg/g.Antioxidant determination of extracts was carried out,which indicated that the response surface model was effective and reliable.The research provided certain theoretical basis for the industrial extraction of vitamin C from catnip.
