Example Embodiment

[0016] Example 1: Preparation of water-soluble pearl powder

[0017] Take the pearl or nacreous layer after rinsing, drying, preliminary crushing, and fine crushing to 120 meshes or more. Take pearl powder and add 10 times the amount of treated purified water (deionized water or distilled water) to make a suspension. Calculate the calcium content in the pearls. Add L-lactic acid in batches to make the calcium carbonate react. Stir continuously at room temperature or 50-100℃ until the pearl powder stops dissolving. After fermentation for 30-36h, boil for 15 minutes and filter to obtain filtrate I; the filter residue is pearl keratin, which is softened with dilute acid and cleaned until no calcium ions For the reaction, add 10 times the amount of distilled water, heat and sterilize, adjust the PH value to 4.5-5.5 after cooling, add 1-3% papain (>2000u / mg) equivalent to the solid content, and hydrolyze at 45-50℃ 4-6 hours, heat to 100℃ to inactivate the enzyme for 10 minutes, then co...

Example Embodiment

[0018] Example 2: Preparation of cell growth factor:

[0019] ① Take chitin and add 9 times the amount of 45% NaOH solution and keep it at 100°C for 3 hours to deacetylate, wash, dry, repeat the operation once to obtain high viscosity chitosan with a deacetylation degree of 97% or more; ② Add 8 times the amount of isopropanol, swell for 1 hour, microwave treatment for 3-5 minutes, add 6 times 45% NaOH solution to alkalize for 1.5 hours, then microwave treatment for 3-5 minutes, add 5-6 times chloroacetic acid dropwise at low temperature Carry out carboxylation treatment at the temperature (below 60℃) for 3h, neutralize with dilute acid, wash with 75% alcohol, dry and pulverize to obtain crude carboxyl chitosan; ③ repeat the operation ② once to obtain a high degree of substitution carboxyl chitosan Sugar, the cell youthful factor, is crushed and packaged for later use.

Example Embodiment

[0020] Example 3

[0021] formula:

[0022] Water-soluble pearl powder 98g cell growth factor 2g

[0023] Preparation:

[0024] The water-soluble pearl powder was prepared according to the method in Example 1, and the cell growth factor was prepared according to the method in Example 2. The said pearl powder is prepared by the following method: take water-soluble pearl powder and cell youthfulness factor, use equal increasing method to fully stir evenly, and seal the package with cobalt 60 radiation sterilization.
