the anti-aging factor is a mixture of hydrogenated polydecene and a dunaliella salina extract, and the dunaliella salina extract accounts for 0.01-0.02% of the weight of the anti-aging factor;
the preparation method of the hydrolyzed wheat fine powder comprises the following steps:
(1) drying, impurity removing, crushing and sieving the wheat bran to obtain fine wheat bran powder with the particle size of 150-250 mu m;
(2) mixing the wheat bran fine powder obtained in the step (1) with water according to a mass ratio of 1: 20-40 to prepare a water suspension, sealing and storing for 8-12 h, and then performing steam explosion, wherein the steam pressure of the steam explosion is 2.0MPa, and the steam explosion time is 1-3 min to obtain a wheat bran suspension;
(3) adjusting the pH value of the wheat bran suspension obtained in the step (2) to 5.0-6.0, adding 2-4 wt% of high-temperature amylase, reacting at 90-100 ℃ for 0.5-1.0 h to remove starch, then cooling to 50-60 ℃, adjusting the pH value to 7.0-8.5, adding 0.1-0.5% of alkaline protease, reacting at 45-60 ℃ for 1-2 h to remove residual protein, centrifuging to remove supernatant, and washing filter residues for 2-5 times;
(4) mixing the filter residue obtained in the step (3) with water according to the mass ratio of 1: 5-18 to prepare a suspension, adjusting the pH to 4.0-6.0, adding a complex enzyme accounting for 2-5% of the mass of the wheat bran in the step (1), and performing enzymolysis reaction at 50-60 ℃ for 1-3 hours to obtain an enzymolysis liquid;
(5) centrifuging the enzymolysis liquid obtained in the step (4), taking supernate, concentrating under reduced pressure to 1/4-1/5 of the original volume, precipitating the obtained concentrated liquid with 65-75% ethanol overnight, centrifuging again to obtain an alcohol precipitate, and drying in vacuum to obtain hydrolyzed wheat fine powder;
wherein the complex enzyme in the step (4) is formed by mixing xylanase and cellulase in a mass ratio of 1: 2-4; and (4) carrying out the enzymolysis reaction under the assistance of ultrasonic waves, wherein the ultrasonic power is 100-120W, and the ultrasonic time is 20-40 min.
2. The hydrolyzed wheat flour-containing composition of claim 1, comprising the following components in weight percent: 0.1-0.4% of hydrolyzed wheat fine powder, 0.03-0.15% of diglucosylgallic acid, 0.5-2% of anti-aging factor, and the balance of water and cosmetically acceptable auxiliary materials.
3. The hydrolyzed wheat flour-containing composition according to claim 1, wherein the cosmetically acceptable auxiliary material is one or more selected from the group consisting of an emulsifier, an emollient, a humectant, a thickener, an antioxidant, a preservative and a perfume.
4. Use of the composition containing hydrolyzed wheat flour according to any one of claims 1 to 3 for preparing a skin care cosmetic.
5. Use of the composition containing hydrolyzed wheat flour in the preparation of skin care cosmetics according to claim 4, wherein the composition containing hydrolyzed wheat flour is used in the preparation of skin whitening and anti-aging cosmetics.
