Embodiment 1
[0020] A preparation method of aloe health tea, specifically comprising the following steps:
[0021] (1) Select the freshly picked aloe vera leaves, wash away the gravel, soil and other impurities with tap water, place the aloe vera leaves in a peeling machine to remove the skin, and quickly place them in 0.9% NaCl solution for 20 minutes for a short time Anti-oxidation. Take out and air-dry until there is no water dripping down, place the aloe soaked in NaCl solution in a low-temperature refrigerator at -10°C for 2 hours, and transfer the frozen aloe to the drying chamber of a freeze dryer, and dry it in vacuum at -5°C for 4 hours. Heat the heating plate in the drying chamber until the temperature of the drying chamber is 50°C, and adjust the vacuum pressure of the drying chamber to 40Pa to keep warm for 2 hours, keep the vacuum pressure of the drying chamber at 40Pa to cool down, and keep it for 3 to 5 hours after the temperature drops to 30°C , to obtain the aloe after va...
