Abstract

The invention provides antioxidant nanometer ethosome rose essence. The antioxidant nanometer ethosome rose essence comprises a vesica structure composed of soya bean lecithin, alcohol, water and EGCG and having a lipid bilayer structure, wherein the capsule core is rose essential oil, the stabilizer sucrose ester and the emulsifier tween-80 are added during the preparation process, then the antioxidant nanometer ethosome rose essence is prepared, and the antioxidant nanometer ethosome rose essence has the oxidization resistance. The antioxidant nanometer ethosome rose essence has stable and permanent aroma, has the aroma type with no change, and is suitable for food, health care and skin care products; the preparation process is convenient to operate, the expensive and complicated instruments are not needed, the stability performance is good under low temperature preservation, and during the preparation and preservation of the antioxidant nanometer ethosome rose essence, the volatilization of the aroma is greatly delayed.

Description

technical field [0001] The invention belongs to the field of daily chemicals, and in particular relates to an anti-oxidation nano-alcohol plastid rose essence and a preparation method thereof. Background technique [0002] With the development and extension of microcapsule technology, nano-microcapsules have been widely concerned. Nanotechnology has been gradually researched and applied in food, skin care products and other aspects. Flavor is a volatile additive that is used in food, cosmetics, etc., and will come into contact with different parts of the human body. Rose essence is the most popular and loved by people, but the general rose essence is an ordinary emulsion, which is a thermodynamically unstable system, prone to stratification, oil slicks, etc., the essence system is easily damaged, and the essence does not have Anti-oxidation function, it is easy to oxidize and cause product quality to decline. Gallocatechin gallate (EGCG) is an antioxidant extracted from t...
