摘  要：
目的:利用响应面优化法对脐橙皮粗多酚的提取条件进行优化。方法:在单因素实验基础上选取实验因素与水平,根据Box-Behnken Design(BBD)实验设计原理采用三因素三水平的响应面分析法,依据回归分析确定各工艺条件的影响因素,以脐橙皮多酚物质含量为响应值作响应面分析实验。结果:分析各个因素的显著性和交互作用后,得出脐橙皮多酚物质浸提的最佳工艺条件为乙醇体积分数51%、浸提温度62℃、浸提时间2h、料液比1:20(w/v)、浸提2次,脐橙皮多酚物质一次提取含量可达20.2mg/g。结论:曲面回归方程与实验结果拟合性好,此模型合理可靠,可用于实际预测。

摘  要：
Objective:The main research object was navel orange peel.Besides,an optimization of extraction process for from navel orange peel was established.Methods:Based on the single factor analysis,a 3-factor,3-level Box-Behnken experimental design was applied to evaluate the effect of the three factors,including extraction temperature,ethanol concentration and ratio of material to liquid.Results:The optimal extraction conditions were ethanol concentration of 51%(v/v),extraction temperature 62℃,extraction time 2h,solid-to liquid ratio 1:20(w/v) and 2 times for extraction.Temperature was the most important affecting factor of polysaccharide extraction,followed by ethanol concentration.Under such extraction conditions,the experimental yield of polyphenols obtained after the first extraction was up to 20.2mg/g.Condusion:It was close to predicted value.
