specific Embodiment approach 1
[0012] Embodiment 1: 1. Raw material pretreatment: cut velvet antler into thin slices with a thickness of 2-3 mm, then vacuum freeze-dry at -40°C to -50°C for 18-24 hours, and pulverize to obtain velvet powder. 2. Preparation of velvet antler extract: add velvet antler powder and extractant at a ratio of 1g: 15mL to 1g: 30mL of solid to liquid, extract at 4°C for 48 hours, and finally use a centrifuge at a speed of 1500 to 2000r / min Solid-liquid separation. 3. Concentration: Concentrate the velvet antler extract by rotary evaporation under the conditions of temperature 40-45° C. and vacuum 0.1-0.15 mbar to obtain a velvet antler extract concentrate. 4. Drying: vacuum freeze-dry the velvet extract concentrate with a vacuum freeze dryer at 0.4 to 0.7 mbar and a temperature of -40 to -50°C. 5. Preparation of black fungus polysaccharides: black fungus powder was degreased by supercritical equipment, then extracted in a water bath, and the extracted polysaccharide solution was dep...
specific Embodiment approach 2
[0013] Specific embodiment two: the difference between this specific embodiment and specific embodiment one is: in step one, the drying temperature of velvet antler is: -40 ℃~-50 ℃, the drying time is 24~36h, and the particle size of pulverized velvet antler is 100~ 200 mesh. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0014] Embodiment 3: This embodiment is different from Embodiment 1 in that in step 2, the extraction agent is an aqueous ethanol solution with a volume fraction of 70%, and the others are the same as Embodiment 1.
