Embodiment 1

[0016] The preparation of embodiment 1 tea seed antioxidant peptide

[0017] (1) Tea seed protein extraction: defatted and tea saponin-free tea seed meal is dissolved in 0.005mol / L ammonium sulfate solution with a solid-liquid ratio of 1:50 (g / mL), and the pH of the extract is adjusted to 10.0 with NaOH solution , centrifuged at 20°C for 180 minutes to obtain a supernatant; add dilute hydrochloric acid solution dropwise to the supernatant to adjust the pH to about 4.0, stir continuously and let it stand for 1 hour, then centrifuge to collect the precipitate as tea seed protein.

[0018] (2) Hydrolyze tea seed protein into polypeptide crude liquid: add solvent water to the tea seed protein according to the ratio of material to liquid 1:10 (g / mL), heat, adjust the pH to about 10 with NaOH solution, and add enzyme-to-bottom ratio of 1.0% Alkaline protease was placed in a constant temperature shaker in a water bath, hydrolyzed at 50°C for 3 hours, the temperature was raised to ina...

Abstract

The invention discloses a method for preparing cosmetics containing tea seed antioxidant peptides, and relates to the formulation and preparation process of skin care cosmetics. Tea seeds are rich in protein. The present invention hydrolyzes the tea seed protein to generate tea seed antioxidant peptides, which are added to skin care cosmetics at a mass percentage of 1-5%, so that the cosmetics have the functions of scavenging free radicals and delaying skin aging. At the same time, tea seed polypeptide also provides nutrients for the skin, which is helpful for skin repair and maintenance.

Description

technical field [0001] The invention relates to skin care cosmetics with anti-oxidation effect, and the main anti-oxidation component in the formula is tea seed anti-oxidation peptide. Background technique [0002] Camellia oleifera is a plant of the genus Camellia in the family Theaceae, which originated in China and is one of the four largest woody edible oil source tree species in the world. Camellia oleifera seed residue after oil extraction contains 10-15% protein, which is a plant protein resource with high nutritional value. According to literature reports, tea seed protein contains 17 kinds of amino acids, including 8 kinds of essential amino acids for human body. After the tea seed protein is hydrolyzed by biological enzymes, polypeptides with various biological activities can be prepared. Studies have shown that tea seed polypeptide is safe, non-toxic, nutritious, and has antioxidant properties, but there is no product containing tea seed polypeptide available. ...
