Abstract

The invention discloses a preparation method of octacosanol-containing lipidosome, including the steps of adding octacosanol and taurine into water-dichloromethane emulsion and performing catalytic synthesis to obtain taurine-octacosanol ester solution; adding cholesterol solution into the taurine-octacosanol ester solution obtained in the first step, performing ultrasonic emulsification, performing rotary evaporation at room temperature to remove dichloromethane to obtain lipidosome solution; hydrating the lipidosome solution, extruding to obtain octacosanol-containing lipidosome with uniformgrain size through a lipidosome extruder, and finally freezing and drying into powder to obtain the finished octacosanol-containing lipidosome product. Since the octacosanol-containing lipidosome isprepared by synthesis of octacosanol and taurine, the problem of poor water solubility of higher aliphatic alcohol is solved, the effect of colourless and odourless is achieved when added to foods, cosmetics and beverages, and the lipidosome has good homogeneity. Besides, octacosanol and taurine have complementary and synergistic effect to the organism and are good for absorption and in-vivo circulation.

Description

technical field [0001] The invention relates to a preparation method and application of octacosanol-containing liposomes, belonging to the field of bioengineering. Background technique [0002] Taurine, also known as taurine, is a sulfur-containing non-protein amino acid, and its chemical name is 2-aminoethanesulfonic acid. It is a sulfur-containing amino acid with various physiological functions in the human body. It is one of the most important amino acids in the human body for brain development, vision enhancement, anti-inflammation, antipyretic, lowering blood pressure, lowering blood sugar, strengthening liver and gallbladder. Taurine has no toxic and side effects, so developed countries attach great importance to its research and application. In recent years, with the in-depth research on its physiological effects and nutritional value, its application has become very extensive. Taurine is widely used as nutritional health products and food additives abroad. According...
