The invention relates to the technical field of
ganoderma processing and specifically relates to a
ganoderma powder preparation method. The
ganoderma powder preparation method comprises the steps: S1,cleaning,
slicing and
drying ganoderma
solid to obtain ganoderma slices for standby application; S2, smashing the ganoderma slices and sieving by a 60-mesh
sieve to obtain ganoderma coarse
powder; S3, jet
wetting the ganoderma coarse powder, putting into a constant-temperature and constant-
humidity culture box to be cultured for 6 hours to obtain wet ganoderma coarse powder, wherein the temperature of the constant-temperature and constant-
humidity culture box is set as 20 to 35 DEG C, and the
humidity of the constant-temperature and constant-humidity culture box is set as 85% to 95%; S4, performing ultralow-temperature
quick freeze and vacuum quick dry on the wet ganoderma coarse powder; S5, then performing air jet pulverization to obtain ganoderma superfine powder; S6, packaging in vacuum and light shielding
modes. The ganoderma coarse powder is treated by jet
wetting, culturing, ultralow-temperature
quick freeze and vacuum quick dry,
cell walls are damaged by larger
temperature difference and ice sublimation, and then a supersonic-speed air-flow smashing technology is utilized to further smash the
cell walls. The
cell walls of the prepared ganoderma powder are completely broken,the technology can greatly reduce the heavy
metal introducing amount, and product safety is improved.
