Abstract
The invention relates to a microcapsule comprising at least one active substance selected from lutein and lutein esters embedded in a matrix comprising fish gelatine and optionally one or more other matrix components, wherein the content of said at least one active substance calculated as free lutein is from 0.5 to 25% of total weight of the microcapsule, and which microcapsule does not comprise any added emulsifier. The invention further relates to a process of preparing the microcapsule as well as uses and products comprising the microcapsule.

A microcapsule comprising at least one active substance selected from lutein and lutein esters embedded in a matrix comprising a low fish bloom gelatin having a strength of 80 bloom or less as the sole agent with dispersing properties present, and optionally one or more other matrix components, wherein the content of said at least one active substance calculated as free lutein is from 0.5 to 25% of total weight of the microcapsule, and which microcapsule does not comprise any added emulsifier.
A microcapsule comprising at least one active substance selected from lutein and lutein esters embedded in a matrix comprising low boom fish gelatine having a strength of 80 bloom or less as the sole agent with dispersing properties present, and optionally one or more other matrix components, wherein the content of said at least one active substance calculated as free lutein is from 0.5 to 25% of total weight of the microcapsule, and which microcapsule does not comprise any added emulsifier obtainable by a process comprising the steps of
- melting or dissolving lutein or lutein ester concentrate(s),
- providing an aqueous solution of said low bloom fish gelatine and said optionally other matrix components,
- mixing said aqueous solution and said melted or dissolved lutein or lutein ester concentrate(s),
- homogenizing the resulting preparation without addition of an emulsifier,
- finely dividing and drying the mixture thus obtained to prepare a mass of particles each containing lutein or lutein ester(s) embedded in said fish gelatine.
A microcapsule consisting essentially of at least one active substance selected from lutein and lutein esters embedded in a matrix consisting essentially of a low fish bloom gelatin having a strength of 80 bloom or less and optionally one or more other matrix components, wherein the content of said at least one active substance calculated as free lutein is from 0.5 to 25% of total weight of the microcapsule, and which microcapsule does not comprise any added emulsifier.
