Die Erfindung betrifft ein Verfahren zur Herstellung von Trockenpulvern eines oder mehrerer Carotinoide, dadurch gekennzeichnet, dass man a) ein oder mehrere Carotinoide in eine wässrige molekulardisperse oder kolloiddisperse Lösung eines Gemisches aus Trehalose und mindestens einem proteinhaltigen Schutzkolloid suspendiert und b) die gebildete Suspension durch Abtrennung des Wassers und gegebenenfalls zusätzlich verwendeter Lösungsmittel und anschließende Trocknung, gegebenenfalls in Gegenwart eines Überzugsmaterials, in ein Trockenpulver überführt. The invention relates to a method for producing dry powders of one or several carotenoids, said method being characterised in that a) one or several carotenoids are suspended in an aqueous molecularly dispersed or colloidally dispersed solution of a mixture consisting of trehalose and at least one protein-containing protective colloid and b) the obtained suspension is transformed into a dry powder by separation of water and, optionally, additionally used solvents and by subsequent drying, optionally in the presence of a coating material. L'invention concerne un procédé de production de poudres sèches d'un ou de plusieurs caroténoïdes, caractérisé en ce qu'il consiste a) à mettre en suspension un ou plusieurs caroténoïdes dans une solution aqueuse en dispersion moléculaire ou colloïdale d'un mélange constitué de tréhalose et d'au moins un colloïde protecteur contenant des protéines et b) à transformer la suspension obtenue en une poudre sèche par séparation de l'eau et, éventuellement, de solvants ajoutés puis par séchage consécutif, éventuellement en présence d'un agent d'enrobage.
