摘　　要：为了研制一种木蝴蝶-苦荞-绿茶复合袋泡茶,并进行配方工艺优化、冲泡条件优化和抗氧化活性评价。先以感官审评为指标,利用单因素和正交试验优化配方工艺最优配比;在最佳组基础上,以感官得分和黄酮含量为综合评价指标,采用响应面试验进行冲泡条件优化,得出最佳冲泡方法。试验结果表明,袋泡茶最佳配方工艺为:绿茶0.5 g,苦荞、木蝴蝶比例3∶1,粒度为10目,每包质量3 g;最佳冲泡方法为:水温93℃、水量120 mL、时间6 min。上述条件下得到的袋泡茶综合得分为0.9096分,总黄酮含量为75.8 mg/L,DPPH自由基清除率达到(88.62±0.46)%,超氧阴离子自由基清除率为(68.42±1.83)%,说明抗氧化活性能力佳。在此条件下得到的袋泡茶茶汤香气浓郁、滋味醇爽、回甘明快、澄清不浑浊,该研究为木蝴蝶-苦荞-绿茶复合袋泡茶提供了理论参考。A kind of Oroxylum indicum-Tartary buckwheat-green tea compound bag tea was developed in this study.The formulation and brewing conditions were optimized,and the antioxidant activity was evaluated.The single factor and orthogonal experiment with the sensory evaluation as investigation index were implemented to optimize the process ratio.On the basis of optimal group,the response surface experiment with the sensory score and the content of flavone as evaluation indexes was used to optimize the foaming conditions.The optimum technological ratio was as follows:0.5 g of green tea,the ratio of Tartary buckwheat and Oroxylum indicum was 3∶1,the granularity of 10 mesh,the mass of each bag was 3 g.The best brewing method was as follows:water temperature of 93°C,water volume of 120 mL,brewing time of 6 min.The overall score of the bagged tea obtained under the above conditions was 0.9096,the content of total flavone was 75.8 mg/L,the DPPH free radical scavenging rate was(88.62±0.46)%,and the scavenging rate of tea decoction to superoxide anion free radical was(68.42±1.83)%,indicating good antioxidant activity.Under these conditions,the tea-bag infusion was rich in aroma,mellow and refreshing in taste,bright and clear in color,which provides a theoretical basis for the development ofOroxylum indicum-Tartary buckwheat-green tea compound bag tea.
