Abstract
The invention relates to stable, pulverulent lycopene formulations, comprising lycopene having a degree of crystallinity of greater than 20%, processes for their preparation and their use as an additive to foodstuffs, cosmetics, pharmaceuticals and animal feedstuffs.
Claims11
A process for the preparation of stable, pulverulent lycopene formulations, comprising lycopene having a degree of crystallinity of greater than 20%, which comprises
- a) preparing a molecularly disperse solution of lycopene, if appropriate together with an emulsifier and/or an edible oil in a water-miscible, organic solvent or a mixture of water and a water-miscible, organic solvent at temperatures of greater than 30° C.,
- b) mixing this solution with an aqueous solution of a protective colloid, the hydrophilic solvent component being transferred into the aqueous phase, and the hydrophobic phase of the lycopene resulting as a nanodisperse phase,
- c) and freeing the formed dispersion from the solvent and the water for the preparation of a water-dispersible dry powder and, if appropriate, drying in the presence of a coating material.
A process for the preparation of stable, aqueous lycopene dispersions, comprising lycopene having a degree of crystallinity of greater than 20%, which comprises
- a) preparing a molecularly disperse solution of lycopene, if appropriate together with an emulsifier and/or an edible oil in a water-miscible, organic solvent or a mixture of water and a water-miscible, organic solvent at temperatures of greater than 30° C.,
- b) mixing this solution with an aqueous solution of a protective colloid, the hydrophilic solvent component being transferred into the aqueous phase, and the hydrophobic phase of the lycopene resulting as a nanodisperse phase.
