响应面优化柑桔皮黄色素微波辅助提取工艺

利用微波萃取技术对柑桔皮黄色素的最佳提取工艺进行了研究，采用单因素试验研究乙醇浓度、微波功率、微波处理时间、料液比、粒度对吸光度的影响，在单因素试验基础上，设计三因素三水平的响应面分析方法对微波提取橘皮黄色素工艺进行优化，建立二次多项式回归方程的预测模型，所得微波提取桔皮黄色素的最佳参数为：桔皮粉粒度为80目（0.198 mm），料液比为1:15（g/mL），乙醇浓度88%，微波时间500 s，微波功率250 W，在此条件下柑桔皮黄色素得率为14.12%。得到的色素产品为黄色，含有类胡萝卜素和黄酮类物质。

Optimization of Microwave Extraction Technology for Yellow Pigment from Orange Peels

Yellow pigment was extracted from orange peels with the method of microwave extraction.The single-factor experiments were used to investigate the effects of particle size,the microwave output power,the microwave extraction irradiation time,ratios of solution to solid and alcohol concentration on absorbance.On the basis of single-factor experiments,a quadratic polynomial regression equation of the forecasting model was set up with Box-Behnken design of three factors and three levels.The optimal conditions of...
