Embodiment 1
[0036] The method for preparing propolis liquid, comprises the steps:
[0037] 1) 1 kg of refined propolis is dissolved in 99 kg of 95% edible alcohol (ethanol) to make a 1% propolis alcohol solution containing propolis by weight;
[0038] 2) Based on the weight ratio of glyceryl monolinoleate and propolis as 1:0.01, put 100kg of 1% propolis liquid into 99kg of glyceryl monolinoleate, or put glyceryl monolinoleate into the propolis liquid , stirring and dissolving, can be slightly heated at 50 ℃ to dissolve, and finally form a transparent eutectic.
[0039] 3) drying this eutectic matter by vacuum drying, the drying temperature is 50°C, and the vacuum degree is -0.090Mpa to obtain propolis liquid, the weight percentage of propolis in the propolis liquid is 1%, and the amount of propolis residue detected is undetected ( Detection limit <0.01%).
[0040] The drying method here can also be replaced by hot air drying method, reduced-pressure rotary evaporation, and reduced-press...
Embodiment 2
[0042] The method for preparing propolis liquid, comprises the steps:
[0043] 1) Dissolving 1.2kg of refined propolis in 0.8kg95% edible alcohol (ethanol) to make a propolis alcohol solution containing 60% propolis by weight;
[0044]2) Based on the weight ratio of glyceryl monolinoleate and propolis as 1:1, put 2kg of 60% propolis liquid into 0.8kg of glyceryl monolinoleate, or put glyceryl monolinoleate into the propolis liquid , Stir to dissolve, and can be dissolved by slight heating at 40°C, and finally form a transparent eutectic.
[0045] 3) Dry the eutectic product by vacuum drying, the drying temperature is 60° C., and the vacuum degree is -0.1 Mpa to obtain propolis liquid. The weight percentage of propolis in the propolis liquid is 60%, and the amount of residual propolis detected is 0.02% of the amount of propolis. %.
[0046] The drying method here can also be replaced by hot air drying method, reduced pressure rotary evaporation, and reduced pressure drying me...
Embodiment 3
[0048] The method for preparing propolis liquid, comprises the steps:
[0049] 1) dissolving 1kg of refined propolis in 3kg95% edible alcohol (ethanol) to make a 25% propolis alcohol solution containing propolis by weight;
[0050] 2) Based on the weight ratio of monolinoleic acid glyceride and propolis as 1:2, put 4kg of 25% propolis alcohol solution into 2kg monolinoleic acid glyceride, or put monolinoleic acid glyceride into propolis In the liquid, stir to dissolve, and can dissolve with slight heat at 60°C, and finally form a transparent eutectic;
[0051] 3) drying this eutectic matter by vacuum drying, the drying temperature is 55°C, and the vacuum degree is -0.095Mpa to obtain propolis liquid, the weight percent of propolis in the propolis liquid is 33.3%, and the detection of propolis residue is undetected ( Detection limit <0.01%).
[0052] The drying method here can also be replaced by hot air drying method, reduced pressure rotary evaporation, and reduced pressure...
