Example Embodiment
[0054] Example 1
[0055] An application of water-soluble pearl powder in promoting wound healing, characterized in that the water-soluble pearl powder has a new purpose of repairing skin wounds;
[0056] The preparation method of the water-soluble pearl powder includes the following steps:
[0057] S1. Pretreatment; washing, drying and preliminarily pulverizing the pearl or nacre into powder with more than 200 mesh;
[0058] S2. Acid modification: Take 80 parts of pearl powder and 20 parts of 37% lactic acid solution in parts by weight. After the two components are mixed, keep the temperature at 70℃ and keep stirring until the pH of the mixed system reaches 5.0, and after it is still When there is no obvious precipitation of insoluble matter, stop heating and cool to room temperature;
[0059] S3. Enzymatic modification; Enzymatic hydrolysis of the liquid obtained from S2, after enzymatic hydrolysis, inactivate the enzyme at 100°C for 10 minutes, centrifuge to take the supernatant, fr...

[0105] An application of water-soluble pearl powder in promoting wound healing, characterized in that the water-soluble pearl powder has a new purpose of repairing skin wounds;
[0106] The preparation method of the water-soluble pearl powder includes the following steps:
[0107] S1. Pretreatment; washing, drying and preliminarily pulverizing the pearl or nacre into powder with more than 200 mesh;
[0108] S2. Modification by acid method; take 85 parts of pearl powder and 24 parts of 45% lactic acid solution in parts by weight. After the two components are mixed, keep the temperature at 80℃ and keep stirring until the pH of the mixed system reaches 5.4 and after it is still When there is no obvious precipitation of insoluble matter, stop heating and cool to room temperature;
[0109] S3. Enzymatic modification; Enzymatic hydrolysis of the liquid obtained from S2, after enzymatic hydrolysis, inactivate the enzyme at 100°C for 10 minutes, centrifuge to take the supern...
