Problems solved by technology

[0009] Looking at the above methods, their raw materials are all high-purity lutein or lutein ester, which is very different from the extract, because the extract cannot be melted and is difficult to dissolve, and its complex composition leads to its special properties. Physical properties; at the same time, the raw materials or processes used in these methods are relatively demanding, and they are unlikely to be used as feed additives

Abstract

The invention discloses a method for preparing a controlled-release type lutein feed additive. The method comprises the following steps: mixing and dissolving lutein extract, glycerin and grease, and dropwise adding alkali liquor under mechanically stirring and shear-emulsifying conditions to completely saponify lutein esters; and then, adding grease and alkali for saponifying, regulating the viscosity and neutralizing, and spraying mixed liquid to granulate so as to obtain the controlled-release type lutein feed additive. According to the method, saponification and microcapsule molding can be realized by a simple method and by utilizing the compound effect of glycerin and grease. Compared with a traditional adsorption technology, the method has the advantages that the chemical stability of lutein in lighting, heating and acidic environments can be effectively improved, and a controlled-release type lutein feed additive product is hardly released in a gastric juice environment and completely released in an intestinal juice environment, so that the controlled-release type lutein feed additive has high bioavailability.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a preparation method of a lutein feed additive. Background technique [0002] Carotenoids (Carotenoids) widely exist in nature, and its most important representatives are β-carotene, astaxanthin, lycopene, canthaxanthin and lutein. Lutein is widely found in vegetables, flowers, fruits and some algae. Lutein has a wide range of uses. In the field of feed, it can be added to chicken feed as a natural colorant to improve the color of egg yolk and chicken skin. For this reason, extracting and separating lutein from natural plants such as marigolds and marigolds has gradually become a research hotspot, and enterprises engaged in this industry are increasing day by day. However, the lutein extracted from plants generally exists in the extract in the form of fatty acid esters, and lutein esters cannot be directly absorbed and utilized by the human body and poultry, and must be ...
