Hyaluronic acid beverage capable of soothing nerves and promoting sleep and preparation method thereof

[0028] Preparation of astragalus polysaccharide calcium

[0029] (1) Weighing the corresponding astragalus polysaccharide, dissolving the astragalus polysaccharide in water to form an astragalus polysaccharide solution;

[0030] (2) Astragalus polysaccharide solution is slowly added dropwise with 2mol / L calcium chloride solution in a water bath at 55±10°C, and the pH value is adjusted to 7.0±0.5 with 20% sodium hydroxide solution;

[0031] (3) After adding the calcium chloride solution, continue to react for 1h, cool to room temperature, and centrifuge at 3000r / min for 10min;

[0032] (4) Take the supernatant, add 3-4 times of absolute ethanol to make it precipitate, and then wash and dry the precipitate to obtain astragalus polysaccharide calcium.

[0033] Preparation of Onion Polysaccharide Calcium

[0034] (1) Weighing the corresponding onion polysaccharide, dissolving the astragalus polysaccharide in water to form an onion polysaccharide solution;

[0035] (2) Slowly ad...
