摘要
以酿酒葡萄皮渣为原料,采用超声波提取方法。在单因素的基础上,通过正交试验确定了酿酒葡萄皮渣色素提取的最优条件:料液比1∶10,pH值3.0,超声温度60℃,超声提取时间为40 min。该提取条件下,酿酒葡萄皮渣色素提取液的吸光度值是0.812。
Taking Grape Skin as raw material,ultrasonic wave extract method is used.On the basis of single factor experiment,through orthogonal experiment to analysis the optimization Proanthocyanidins from Grape Skin Extraction condition in concentration： Liquid ratio is 1∶10,pH is 3.0,temperature is 60 ℃,concentration time is 40 min,absorbance of Proanthocyanidins from Grape Skin Extraction condition is 0.812.
