摘　　要：以藏茶、玫瑰、乌梅为主要原料,以赤藓糖醇、三氯蔗糖为辅料,研制藏茶玫瑰乌梅无糖复合饮料。以感官评分为指标,利用单因素与响应面法优化得到复合饮料的最佳配方为:藏茶浸提液添加量42%、玫瑰浸提液添加量20%、乌梅浸提液添加量18%、赤藓糖醇添加量3%、三氯蔗糖添加量0.007%。利用UHPLC-QqQ-MS/MS检测出复合饮料中有12种功能性成分,其中儿茶素类有5种。功能性成分中含量前5位为异槲皮素、槲皮素-7-葡萄糖苷、表没食子儿茶素没食子酸酯、绿原酸和芦丁。体外抗氧化试验结果显示复合饮料对DPPH自由基清除率为(78.26±1.74)%,对羟基自由基清除率为(93.58±2.21)%,还原力为2.295±0.017。该复合饮料功能性成分丰富,抗氧化能力较好,呈褐红色、澄清透明,具有藏茶和玫瑰特有的香气,酸甜适宜,口感好。A new sugar-free compound beverage was prepared using Tibetan tea,rose and Mume Fructus as the main raw materials,erythritol and sucralose as the auxiliary materials.The optimal formula of compound beverage was obtained by single factor test and response surface methodology with sensory evaluation score as index.The formula comprises the following components:Tibetan tea extract 42%,rose extract 20%,Mume Fructus extract 18%,erythritol 3%,and sucralose 0.007%.UHPLC-QqQ-MS/MS analysis detects 12 kinds of functional components in the compound beverage,including 5 kinds of catechins.The top five functional components were isoquercetin,quercetin-7-glucoside,EGCG,chlorogenic acid and rutin.The scavenging rate of DPPH free radical,hydroxyl free radical and the reducing power was (78.26±1.74)%,(93.58±2.21)% and 2.295±0.017,respectively.The compound beverage has rich functional components,owning good antioxidant capacity,maroon color,clarity and transparency,distinct fragrance of Tibetan tea and rose,proper sweet and sour taste and good taste.
