Redispersible dry powder containing oxygen-containing carotenoid, useful e.g. as dye in foods, feed or pharmaceuticals, prepared in presence of partially degraded soya protein as protective colloid

摘要

A dry powder (A) comprising oxygen-containing carotenoid(s) is prepared by dispersing (I) in an aqueous molecular dispersion or colloidal solution of a protective colloid (II) ((II) is soya protein with a degree of degradation of more than 5%) and converting the dispersion into (A) by removing the water (and any additional solvent) and drying (optionally in presence of a coating material). An Independent claim is included for the powder (A) obtained by the process.
