Embodiment 1
[0024] The embodiment of the present invention provides a preparation method of polypeptide firming freeze-dried powder for improving aging skin. The ingredients of the polypeptide freeze-dried powder are: 15 parts of mannitol, 13 parts of trehalose, 22 parts of polyglutamic acid, 28 parts Consists of oligopeptides, 8 parts of collagen amino acids, 20 parts of retinol, 33 parts of methionine and 42 parts of water.
[0025] Preferably, the mannitol is extracted by catalyzing and hydrogenating fructose, and the trehalose is extracted by using trehalose-producing yeast and bacteria as starting strains to select a high-yield trehalose-producing strain, ferment and produce trehalose, and then It is extracted and refined by means of effective separation and extraction.
[0026] Preferably, the following preparation steps are included:
[0027] S1: Mix and stir mannitol, trehalose, polyglutamic acid and methionine in a ratio of 10:6:13 to make them evenly mixed;
[0028] S2: After ...

The ingredients of the polypeptide freeze-dried powder are: 10 parts of mannitol, 8 parts of trehalose, 20 parts of polyglutamic acid, 25 parts of Consists of oligopeptides, 5 parts of collagen amino acids, 15 parts of retinol, 30 parts of methionine and 40 parts of water.
[0047] Preferably, the mannitol is extracted by catalyzing and hydrogenating fructose, and the trehalose is extracted by using trehalose-producing yeast and bacteria as starting strains to select a high-yield trehalose-producing strain, ferment and produce trehalose, and then It is extracted and refined by means of effective separation and extraction.
[0048] Preferably, the following preparation steps are included:
[0049] S1: Mix and stir mannitol, trehalose, polyglutamic acid and methionine in a ratio of 8:10:5 to make them evenly mixed;
[0050] S2: After...
