摘要
为充分利用蓝莓酒渣中的多酚资源,在单因素试验基础上,采用溶剂提取法对蓝莓酒渣中多酚的提取工艺进行了研究。结果表明,蓝莓酒渣中多酚的最优提取工艺为:提取剂0.1%盐酸的60%乙醇水溶液,料液比1∶40(g∶m L),提取温度80℃,提取时间3 h。此条件下蓝莓酒渣中多酚提取量为8.89 mg·g^(-1),粗提取物得率22.1%,总酚纯度为5.69%。为蓝莓酒渣的利用及生物活性成分研究提供了依据。
To take full advantage of polyphenols resources in blueberry wine pomace,solvent extraction process of polyphenols from blueberry wine pomace was studied on the basis of single factor test. The results showed that the optimum extraction process of polyphenols in blueberry wine pomace included 60% ethanol aqueous solution containing 0.1% hydrochloric acid as extraction solvent,solid-liquid ratio of 1∶40（g∶m L）,extraction temperature of 80 ℃,and extraction time of 3 hours. Under these conditions,the extraction amount of polyphenols was 8.89 mg·g^（-1）,the yield of crude extract was 22.1% and total phenols purity was 5.69%. It provided the basis for the research and utilization of bioactive constituents in blueberry wine pomace.
