Abstract

The invention discloses a microwave drying method for preparation of pitaya flower tea. The method is as below: drying fresh pitaya flowers a microwave oven; heating 3-5 times, after each heating, taking the fresh pitaya flowers from the microwave oven, rapid cooling by cold air to 25-30 DEG C, and then placing the fresh pitaya flowers into the microwave oven for the next drying; successively reducing the output power of the microwave oven and then carrying out several times of alternate heating and rapid cooling; when the water content of the pitaya flowers is no higher than 5%, taking the pitaya flowers out of the microwave oven, drying by cold air and cooling to obtain the pitaya flower tea. The method not only can maintain the shape and color of pitaya flower, and but also better retains the active ingredients, reaches good flavor, texture and reconstitution property, and improves the quality of the pitaya flower tea.
