Beschreibung
Zusammenfassung:	The invention relates to an aqueous transparent oil-in-water emulsion comprising an emulsified carotenoid in a concentration of 0.025-2000 ppm. Some claims relate to a process including the step of a) manufacturing a solution comprising modified starch and/or at least one surface active protein and water, b) manufacturing a solution by mixing at least one carotenoid in triacylglycerol oil and melting the dispersed carotenoid at a temperature of 100 - 200[deg.]C c) introducing the solution of step b) into solution of step a), d) performing at least one step of pre-emulsification by passing the mixture of step c) through a rotator/stator mixer, e) performing at least one step of high pressure homogenization, f) spray drying the emulsion of step e) to obtain a powder. The emulsion or the powder is useful as a food colorant or as replacement for azo dyes.
