Preparation method of antioxidant purified active propolis freeze-dried powder

The invention discloses a preparation method of antioxidant purified active propolis freeze-dried powder, belonging to the technical field of the preparation technology for pure propolis freeze-dried powder. The preparation method comprises the following steps: (1) collecting active raw propolis, purifying by adopting edible alcohol, filtering to obtain active pure edible alcohol, and carrying out low-temperature vacuum freeze drying on the active pure edible alcohol at -35 DEG C to obtain active propolis freeze-dried powder for later use; (2) cleaning Shepody antioxidant potatoes, peeling, boiling, smashing, drying by adopting a climbing film evaporator, damaging the molecular structure of the Shepody antioxidant potatoes by adopting a high speed freezing centrifuge, and finally smashing and filtering to obtain modified starch for later use; and (3) mixing the active propolis freeze-dried powder and the modified starch, uniformly mixing under low temperature vacuum drying environment, and preparing the mixture into capsules or pellets. The invention aims at providing the preparation method of antioxidant purified active propolis freeze-dried powder, which is long in expiration date and scientific in technology. The preparation method is used for preparing the propolis freeze-dried powder.
