摘要
以红枣、枸杞、绿茶为原料,研制红枣枸杞茶饮料。对枸杞、红枣进行了最佳干燥工艺条件的研究,并通过正交试验结合感官评定确定饮料的最佳配方。结果表明,红枣最佳干燥方法为远红外烤箱干燥,干燥温度80℃,干燥时间60 min;枸杞最佳干燥方法为远红外烤箱干燥,干燥温度70℃,干燥时间30min;红枣枸杞茶饮料最佳配方为枸杞汁、茶汤、红枣汁(体积比)1.0∶6.0∶3.0,蔗糖添加量10%;pH 4.5。
The red date medlar-green tea drink was produced by the red date、 Chinese medlar and green tea. Studies on the optimum drying technology conditions, material preparing for the best tastes, the optimum stability of the drink were conducted. The results showed that the optimum conditions for drying the Chinese date included far infrared drying oven, drying time 60 min, drying temperature 80 ℃. The optimum conditions for drying the medlars included far infrared drying oven, drying time 30 min, drying temperature 70 ℃. The best formula of the red date medlar-green tea drink included Chinese medlar, green tea and red date with 1.0∶6.0∶3.0. The optimum sugar content of drink was 10%. The optimum pH of drink was 4.5.
