preparation example Construction
[0052] The present invention also provides a method for preparing high-purity mushroom β-glucan powder, comprising: adding an excipient to the mushroom β-glucan prepared by the above-mentioned preparation method to form a compound; and drying the compound .
[0053] The drying step includes spray drying or freeze drying to dry the compound.
[0054] The excipients include lactose, sucrose, glucose, fructooligosaccharide, starch or starch derivatives, and dietary fiber. In a specific embodiment, the excipient is dietary fiber. In another specific embodiment, the dietary fiber includes dextrin, and the dextrin is especially preferably Fibersol-2. Because the Fibersol-2 has good water solubility and good adsorption capacity for polysaccharides, the concentration of mushroom β-glucan powder in the mushroom β-glucan powder can be effectively increased through drying treatment, especially when spray drying is used. The moisture content of the processed mushroom β-glucan powder pr...
Embodiment 1 to 6
[0071] Embodiment 1 to 6: the test that culture fluid composition influences polysaccharide body output
[0072] One liter of culture liquid is prepared in a fermentation vessel with sterile water as a solvent, and trehalose, mannose and glucose are used as carbon sources of the culture liquid, and the weight ratio of the trehalose, mannose and glucose is 1:1:1, Use 0.5% by weight of yeast extract as the nitrogen source of the culture solution; then, put the configured production medium together with the fermentation vessel into a high-pressure steam sterilizer for high-temperature and high-pressure sterilization, and the sterilization conditions are 121 ° C, 15 minutes for sterilization Afterwards, cool at room temperature, then add the ganoderma lucidum mycelium, and cultivate for about 15 days at a speed of 30 to 100 rpm, so that the mushroom mycelium can synthesize a large amount of mushroom β-glucan in the culture solution.
[0073] The fermented culture solution containi...
Embodiment 4
[0075] The treatment method of Example 4 is the same as that of Example 1, but the mannose of the culture medium is changed to mannitol as shown in Table 1, and the result of the composition of the culture medium on the yield of mushroom β-glucan is evaluated.
[0076] The treatment methods of Examples 5 to 6 are the same as in Example 4, but the types of mushrooms are changed to Schizophyllum and Antrodia Cinnamomea as shown in Table 1, and the results of the composition of the culture solution on the yield of mushroom β-glucan are evaluated.
