Abstract

The invention discloses a preparation method of carotenoid emulsion and microcapsules. The method is characterized in that the electrostatic force interaction of emulsifier molecules on an emulsion interface is utilized, and a two-step homogenization method is applied to preparing carotenoid bilayer emulsion which can be further dried to prepare carotenoid microcapsules. The method disclosed by the invention is simple, convenient and feasible for preparation, the used emulsifier and microcapsule wall materials have favorable biocompatibility and can be biodegraded, and a material source range is wide; and the carotenoid emulsion and microcapsules have the characteristics of good physical and chemical stability, long shelf life and the like, the carotenoid loading capacity of the emulsion can reach 2%, and the carotenoid loading capacity of the microcapsules can reach 10%.

Description

technical field [0001] The invention relates to the technical field of processing and application of medicine, food and health food, and relates to a preparation method of carotenoid emulsion and microcapsule. Background technique [0002] In recent years, nutrition and health have gradually become the mainstream of food consumption in the new century. At present, about 10% of adults in the world are in a sub-health state, and the incidence of chronic diseases such as obesity, hepatitis, high blood pressure, high blood sugar, arteriosclerosis and cancer is also increasing year by year. Therefore, the development of health food, especially health food with anti-oxidation, anti-virus, blood fat-lowering, and immune-enhancing functions to improve the health status of sub-healthy people will improve the overall physical fitness of our nationals and ensure the continuous, rapid and healthy development of our country. Development has important theoretical and practical significan...
