Embodiment 1
[0033] A preparation method of water-soluble functional red yeast rice powder, specifically comprising:
[0034] The first stage of solid-state fermentation includes the following specific steps:
[0035] (1) Strain activation: the pure strain of Monascus was inserted into the plate medium, and cultured at 30°C for 5 days to activate the strain;
[0036] (2) Preparation of primary seed liquid: Add 20 mL of sterile saline to the plate culture medium of activated strains, rub the mycelium back and forth with an inoculation loop to wash the spores and mycelium to make a plate seed liquid, press 2% The inoculation amount is inoculated into the seed medium, 30°C, 100rpm, and cultivated for 48 hours;
[0037](3) Preparation of the secondary seed solution: inoculate the primary seed solution into the seed medium (250mL / 1000mL) at an inoculum volume of 10% under sterile conditions, and cultivate for 24 hours at 30°C and 100rpm;
[0038] (4) Solid-state fermentation: Under sterile co...
