Example Embodiment

[0016] Example 1 Preparation of tea seed antioxidant peptide

[0017] (1) Extracting tea seed protein: defatted and defatted tea seed meal is dissolved in 0.005mol / L ammonium sulfate solution at a material-to-liquid ratio of 1:50 (g / mL), and the pH of the extract is adjusted to 10.0 with NaOH solution After leaching at 20°C for 180 minutes, the supernatant was obtained by centrifugal separation; the supernatant was dripped with dilute hydrochloric acid solution to adjust the pH to about 4.0, stirring constantly and standing for 1 hour, centrifugation, the collected precipitate was the tea seed protein.

[0018] (2) Hydrolyzed tea seed protein is a crude polypeptide solution: add solvent water to the tea seed protein at a material-to-liquid ratio of 1:10 (g / mL), heat, adjust the pH to about 10 with NaOH solution, and add 1.0% enzyme base The alkaline protease is put into a constant temperature shaker in a water bath, hydrolyzed at 50°C for 3 hours, heated to inactivate the enzyme, c...

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. ...
