【摘要】 以猕猴桃果汁为原料,通过单因素实验和正交实验,对影响多酚提取量的提取剂种类、提取剂体积分数、提取时间、提取温度和料液比等因素进行探讨,确定猕猴桃多酚的最佳提取工艺参数为:体积分数为80%的甲醇按料液的体积比1∶3,在温度50℃下浸提45min,多酚的提取量可达到729.545mg/L。更多还原

【Abstract】 The factors of extractant concentration,extraction time,temperature,material-liquid ratio,and so on,which influence the extraction yield in the technology for extraction of polyphenol from Kiwi juice,were researched through a single factor experiment and orthogonal experiment.The optimum technological parameters for extraction of total polyphenol was determined:methanol volume fraction 80%,temperature 50℃,material-liquid ratio 1∶3 and extraction time 45min.The yield of polyphenol could reach 729.545mg/L.更多还原
