Embodiment 1

[0016] Embodiment 1: the preparation of water-soluble pearl powder

[0017] The pearl or nacre layer is taken, rinsed, dried, primary crushed, and finely crushed to a size above 120 mesh. Take pearl powder and add 10 times the amount of treated clean water (deionized water or distilled water) to make a suspension. Calculate the calcium content in pearls, and add L-lactic acid in batches in proportion to make the calcium carbonate react. Stir continuously at room temperature or 50-100°C until the nacre powder stops dissolving, ferment and cultivate for 30-36 hours, boil for 15 minutes, and then filter to obtain filtrate I; the filter residue is pearl keratin, which is softened with dilute acid and washed until there is no calcium ion To react, add 10 times the amount of distilled water, heat and sterilize, adjust the pH value to 4.5-5.5 after cooling, add papain (>2000u / mg) equivalent to 1-3% of the weight of the solid, and hydrolyze at 45-50°C For 4-6 hours, heat to 100°C to ...

Embodiment 2

[0018] Embodiment 2: the preparation of cell young factor:

[0019] ① Take chitin and add 9 times the amount of 45% NaOH solution, put it in an environment of 100 ° C for 3 hours for deacetylation treatment, wash, dry, and 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, microwave for 3-5 minutes after swelling for 1 hour, add 6 times of 45% NaOH solution to alkalinize for 1.5 hours, then microwave for 3-5 minutes, add 5-6 times of chloroacetic acid dropwise at low temperature Carboxylation treatment at low temperature (below 60°C) for 3 hours, neutralized with dilute acid, washed with 75% alcohol, dried, and pulverized to obtain crude carboxy chitosan; ③Repeat operation ② once, purify and crystallize to obtain carboxy chitosan with high substitution degree Sugar, that is, cell young factor, is crushed and packaged for later use.
