金银花·红茶复合保健饮料的工艺研究

目的]研究金银花、红茶复合保健饮料的工艺。方法]以金银花、红茶提取液、蔗糖、柠檬酸为主要原料,经调配、灌装、杀菌(85~90℃,1~2 min)等工艺制成一种新型保健饮料。通过L9(34)正交试验,分别确定了金银花、红茶的最佳提取工艺及其复合保健饮料的最佳配方。结果]金银花的最佳提取工艺为:加水量为40倍,浸提温度90℃,浸提时间30 min;红茶的最佳提取工艺条件为:加水量为50倍,浸提温度80℃,浸提时间15 min;金银花、红茶复合保健饮料的最佳配方为:金银花与红茶提取液体积比3∶7,糖11%,柠檬酸0.05%。结论]该产品具有金银花的甘苦和红茶浓郁的茶香,酸甜适中,清爽适口,并具有消炎解毒、降脂明目等作用。

Technical Study on Compound Health Beverage of Honeysuckle and Black Tea

Objective] The purpose of the research was to investigate the processing technique of compound health beverage of honeysuckle and black tea.Method] With the extracted liquids of honeysuckle and black tea,sugar,and citric acid as main material,a new type of health beverage was made via preparing,filling,sterilization(85～90 ℃,1～2 min) and other processing technique.Through the L9(34)orthogonal experiment,the optimal extraction processing technique of honeysuckle and black tea as well as the optimal formula of its compound health beverage were ascertained separately.Result] The optimal extraction processing technique of honeysuckle was adding water 40 times of the honeysuckle and extracting at 90 ℃ for 30 min.The optimal extraction processing technique of black tea was adding water 50 times of the black tea and extracting at 80 ℃ for 15 min.The optimal formula for the compound beverage was as follows: the volume ratio of the extracting solutions of honeysuckle to black tea was 3∶7,with 11% sugar and 0.05% citric acid.Conclusion] This product had the sweetness and bitterness of honeysuckle,and the strong fragrance of black tea.It was moderately sweet and acid,with a refreshing and delectable flavour.Moreover,it had functions of antiphlogosis,detoxification,lowering lipid and improving eyesight,etc.
