FORMULATION OF ASTAXANTHIN DERIVATIVES AND USE THEREOF III

摘要

The invention relates to formulations of an astaxanthin derivative, comprising a continuous oil phase with at least one oil that is suitable for foodstuffs and an aqueous phase that is emulsified in the oil phase, the astaxanthin derivative being present in the aqueous phase in the form of dispersed particles that are stabilised by at least one protective colloid. The astaxanthin derivative consists of at least 70 % by weight, preferably at least 80 % by weight, in particular at least 90 % by weight and especially 96 % by weight of a compound of formula (I) below. In formula (I), R represents a group of formula (III), where # is the link to the carbonyl group, A represents -CH2CH2- or -CH=CH- and Rx represents C1-C4 alkyl.
