摘  要:
研究了用乙醇提取梨渣中多酚物质的方法,着重研究了醇提多酚时乙醇浓度、提取温度、提取时间、料液比对提取量的影响,主要目的:充分提高梨渣的综合利用程度,为梨渣提取多酚物质的工业化生产奠定基础。正交试验结果表明:乙醇浓度75%,料液比1∶12,提取时间6 h,提取温度60℃的条件下,提取效果最佳,提取量可达到1.73 mg/g。

摘  要:
The optimum extraction process of pear pomace-polyphenols with ethanol-water was studied in the paper,some factors including the concentration of ethanol、extracting temperature、extracting time、the ratio of pear pomace to extract were studied particularly,the objective was to enhance the using degree of pear pomace in order to establish the industrialized production of pear pomace-polyphenols.the optimum technological conditions were obtained: the concentration of ethanol 75%,extracting temperature 60 ℃、extracting time 6 h、the ratio of pear pomace to extractant 1∶12,the quantity of extraction on this condition was 1.73 mg/g.
