摘要
以破碎的菜籽为原料,在单因素试验基础上,采用响应曲面分析对提取菜籽多酚有显著性影响的4个因素(乙醇浓度、提取温度、提取时间和提取次数)进行优化,得到最佳提取工艺条件为乙醇体积分数65%,提取温度70℃,提取时间50min,料液比1∶8(m∶V),盐酸含量0.04%,振荡器转速200r/min,提取3次。该条件下,总多酚提取率达到75.39%。
Broken rapeseed as raw materials,based on single factor experiments,response surface analysis was taken to optimize four significant influential factors（ethanol concentration,extraction temperature,extraction time and extraction times）,which is greater impact on the extraction of rapeseed polyphenols.The best extraction conditions for the concentration were ethanol content 65%（V/V）,extraction temperature 70 ℃,extraction time of 50 min,feed liquid ratio of 1∶8（m∶V）,hydrochloric acid content of 0.04%,oscillator speed 200 r/min,3 times extracted.Under this condition,the total polyphenol extraction rate reached 75.39%.
