Method for preparing lutein oleoresin microcapsule

Abstract

The invention discloses a method for preparing a lutein oleoresin microcapsule, which comprises the steps of: 1) preparing a lutein oleoresin core material, 2) preparing a capsule material, 3) mixing the lutein oleoresin core material with the capsule material and uniformly emulsifying the mixture into emulsified liquid at nanometer level, and 4) drying the emulsified liquid. The method of the invention uses the microcapsule technique to treat the lutein oleoresin and uses natural or synthesized high polymer material to pack the lutein oleoresin drops into a microcapsule, so the obtained product has better water-solubility and stability, the industrial production can be realized, and the problems of the prior art that the application scope is narrow and the stability is inferior are solved.

Description

technical field

[0001] The invention relates to the field of bioengineering, in particular to a method for preparing lutein oleoresin microcapsules. Background technique

[0002] Carotenoids are fat-soluble plant pigments widely found in nature. Carotenoids are mainly divided into two categories: carotene and lutein. Natural lutein, also known as plant "lutein", exists in the form of esters (ie lutein oleoresin) combined with higher fatty acids such as palmitic acid, stearic acid, lauric acid or myristic acid. Medical experiments have proved that lutein contained in plants is an antioxidant with excellent performance. Adding a certain amount of lutein to food can prevent a series of diseases caused by cell aging and aging of body organs, such as retinal macular degeneration , cataract, colon cancer, cardiovascular sclerosis, coronary heart disease, etc. At the same time, lutein can also be used as a feed additive for the coloring of poultry meat and eggs, and it has also...
