| Abstract: | This article introduces the technique of producing quick-dissolving health care tea which is chisty tea.Microwave extraction method is used to extract water-soluble substance.Specific researches are made to find the influence of microwave power,extraction time,alcohol thickness,rate of material and solution and extraction times on obtainment percentage and quality.The result indicates that the technique needs shorter time,has higher obtainment percentage,and is easier to industrialize.The best technological conditions are:microwave power 640W,extraction time 120～150 seconds,rate of material and solution 1∶15,alcohol thickness 50%,extraction times twice. |
