Compound natural antioxidant for keratin preparation and preparation method of nanoemulsion of compound natural antioxidant

Abstract

The invention provides a compound natural antioxidant for keratin preparation and a preparation method of nanoemulsion of the compound natural antioxidant. The compound natural antioxidant comprises flavonoid, polysaccharide active matter, and one or more of vitamins A, C and E extracted from natural plants, and reduced glutathione-S-monoether. The compound natural antioxidant is further prepared into the nanoemulsion with high solubility in water, is applied to a keratin preparation technology and has the advantages of environmental protection and high oxidation resistance; furthermore, ingredient structures of the compound natural antioxidant are complete and reasonable; and the compound natural antioxidant has strong synergism, and can carry out oxidation protection during the whole course from a hydrolysis production process of keratin to a protein product to ensure safety and sanitation of the protein product from beginning to end.

Description

technical field

[0001] The invention belongs to the technical field of antioxidants, and in particular relates to a compounded natural antioxidant used in the preparation of keratin and a method for preparing nanoemulsions thereof. Background technique

[0002] Extracting keratin from animal hair, poultry feathers, etc. to use as feed or health nutrition products to turn waste into treasure, this technology is more popular, but the problem that still exists at present is that the keratin produced by the existing technology The hygienic quality of protein products is not stable and reliable enough, especially when added to food, it is still not very reassuring. The reason is that Maillard side reactions often occur when keratin is hydrolyzed, which is the source of toxins, in which various free radicals such as hydroxyl radicals, peroxyl groups and single linear oxygen can be derived Hundreds of toxic substances are produced, so controlling and quenching free radicals h...
