Title:
LUTEIN FEED ADDITIVE PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/005087
Kind Code:
A1
Abstract:
Provided is a controlled-release lutein feed additive preparation method, comprising the steps of: mixing and dissolving a lutein extract, glycerol, and an oil or fat, and dropping a lye therein under mechanical stirring and shear emulsification, so as to completely saponify a lutein ester; and then adding the oil or fat and the lye for saponification, and performing spray granulation on a mixture after adjusting a viscosity thereof and neutralization thereof, so as to obtain a controlled-release lutein feed additive. The method uses glycerol and an oil or fat, and performs saponification and microcapsule formation thereon, thereby improving chemical stability of lutein in a light-exposed, hot and acidic environment. The controlled-release lutein feed additive is unlikely to be released in gastric juices, but is completely released in intestinal juices, thus having higher bioavailability.
