Preparation of Compound Beverage of Siraitiae Fructus

A compound beverage of siraitiae fructus was prepared using siraitiae fructus,lemon slices and kumquat as the main raw materials.With sensory score as the index,the single factor experiment and orthogonal design were employed to optimize the formulation and technology parameters of the compound beverage.The results showed that the optimal extraction conditions were as follows:the temperature was 80℃,the extraction time was 40 min,and the ratio of material to liquid was 1∶40(g/mL).And the optimal formulation of the compound beverage was siraitiae fructus∶lemon slices∶kumquat=4∶1.5∶1.5.The compound beverage produced by this formulation and process was brown,clear and transparent with favourite flavor.
