中文摘要: 通过专一酵母菌株对肉苁蓉和葡萄汁进行发酵,采用单因素和响应面试验确定肉苁蓉葡萄酒的关键发酵工艺参数,并测定DPPH 自由基(DPPH·)、ABTS+自由基(ABTS+·)、羟基自由基(·OH)清除能力及还原能力,考察肉苁蓉葡萄酒的抗氧化活性。结果表明,在接种量0.06%,发酵温度26 ℃,原料质量比1∶4 的工艺条件下,肉苁蓉葡萄酒的酒精度为5.60%vol,感官评分93。肉苁蓉葡萄酒对DPPH·、ABTS+·、·OH 的清除率及还原能力分别为96.53%、95.64%、96.86%及97.39,表明其具有一定的抗氧化活性。
Abstract:The Cistanche deserticola wine was fermented by a specific yeast strain,and the key fermentation control parameters of C.deserticola wine were determined by single factor and response test.The antioxidant activity of C.deserticola wine was determined by the scavenging and reducing ability of DPPH free radical(DPPH·),ABTS free radical(ABTS+·),and hydroxyl free radical(·OH).Under the conditions of inoculation amount of 0.06%,at the fermentation temperature of 26 ℃,and with the raw-material ratio of 1∶4,the alcohol content of C.deserticola wine was 5.60%vol and the sensory score was 93.The scavenging rate of C.deserticola wine to DPPH·,ABTS +·,·OH and the reducing ability were 96.53%,95.64%,96.86% and 97.39,respectively,indicating that it had certain antioxidant activity.
