苹果渣中多酚物质的提取技术研究

Study on the Extraction Process of Polyphenols from Apple Pomace

研究了用乙醇为溶剂提取苹果渣中多酚物质的最佳工艺,考察了乙醇提取时乙醇浓度、料液比、提取时间和提取温度对提取率的影响;正交试验结果表明,最佳浸提条件为乙醇浓度60%,提取温度60℃,提取时间4 h,料液比1∶12;此条件下提取量为1 072.615 mg/kg。

The optimum extraction process of polyphenols in apple pomace with ethanol--water was studied in this paper, Some factors, including the concentration of ethanol, the ratio of apple pomace to extractant, extracting time, extracting temperature ; the optimum technological conditions were attained by the orthogonal experiment as follows, the concentration of ethanol 60 %, extraction temperature 60℃, extraction time 4 h, the ratio of apple pomace to extractant 1 ： 12. The quantity of extraction under this condition was 1 072. 615 mg/kg.
