[0037] The present invention further proposes a kind of preparation method of skin care composition as above, the preparation method of described skin care composition comprises the following steps:
[0038] Step S10, using the first complex protease to enzymatically hydrolyze the almond protein inclusions to obtain almond protein peptides.
[0039] Wherein, the first composite protease is composed of alkaline protease and neutral protease; the enzymolysis conditions of the first composite protease are temperature 52-56°C, pH 8.0-8.5, preferably temperature 55°C, pH 8.0 . Since both alkaline protease and neutral protease have different action sites and can act on different peptide bonds of almond protein, the combination of the two can fully decompose almond protein into small molecular peptides with smaller molecular weights. Compared with the existing Protease, the small molecular peptides produced by enzymatic hydrolysis not only have a high proportion, small molecular wei...
Embodiment 1
[0046] Skin care composition: 55 parts of almond protein peptide, 8 parts of small molecule whey protein peptide and 6 parts of almond oil.
[0047] Preparation method: at a temperature of 55°C and a pH of 8.0, use the first composite protease composed of alkaline protease and neutral protease at a ratio of 1:1 to enzymolyze almond protein powder to obtain almond protein peptide; at a temperature of 45 ℃, pH 7.5, using the second compound protease composed of papain and trypsin at a ratio of 1:2, to enzymolyze whey protein to obtain small molecule whey protein peptide; according to the formula of the above skin care composition, weigh The almond protein peptide and small molecule whey protein peptide are crushed through a 500-mesh sieve, mixed evenly with almond oil, and dried to obtain a skin care composition.
Embodiment 2
[0049] Skin care composition: 26.7 parts of almond protein peptide, 3.3 parts of small molecule whey protein peptide and 5 parts of small white almond oil.
[0050] The preparation method is the same as in Example 1.
