Abstract:
The invention relates to the production of solutions of astaxanthin derivatives in edible oils and to solutions of astaxanthin derivatives in an edible oil that can be obtained by said method. The inventive method comprises: i) provision of a suspension of an astaxanthin derivative in an edible oil, the particles of the astaxanthin derivative in the suspension having an average volumetric particle diameter, determined by Fraunhofer diffraction, ranging between 0.5 and 50 µm, and ii) the suspension of the astaxanthin derivative is worked into an edible oil to produce a solution of the astaxanthin derivative of formula (I), at least 70 % by weight of said astaxanthin derivative being composed of a compound of formula (I). In said formula, R represents a group of formula (II), # represents the bond with the carbonyl group, A stands for linear or branched C1-C6alkene or for -CH=CH- and Rx stands for C1-C10 alkyl.
