Embodiment 1
[0022] A preparation method of dendrobium tea is made from dendrobium as raw material, comprising the following steps:
[0023] (1) After the dendrobium is harvested, it is washed, cut into sections, and baked in a constant temperature drying room at a temperature of 60°C for 16 hours;
[0024] (2) Microwave treatment after leaving the drying room for about 2.5 minutes to obtain dry tea;
[0025] (3) Add 4 times the amount of water to the dry tea obtained in step (2), adjust the pH=7 with NaOH, decoct for 1 hour, collect the filtrate, add 3 times the amount of water to the filter residue, decoct for 0.5 hours, collect the filtrate, and combine the filtrates;
[0026] (4) Concentrate the filtrate obtained in step (3) at 70°C to a relative density of 1.1, and add ethanol until the alcohol content is 65%;
[0027] (5) Stand still for 12 hours, filter, take the supernatant to recover ethanol and concentrate to obtain Dendrobium extract;
[0028] (6) Use fluidized bed drying or m...
