Abstract: Provided is an emulsion with an aqueous phase and an oil phase including one or more liposoluble components as well as one or more emulsifiers in the aqueous phase, selected from the group of saponins, preferably quillaia extract, and one or more esters of a vegetable lipid with a food acid in the oil phase. The combination of ester(s) and saponin(s) has a particularly advantageous and unexpected effect for emulsions: thus stable emulsions, preferably stable microemulsions are obtained, which have a high acid stability so that the emulsion is in particular suitable for use in very acidic beverages in the range of pH?3.5. Furthermore, the oxidative stability of the emulsion is improved. If a colorant is emulsified, a premature colorfading can be prevented. In addition, the light stability of the emulsion is increased. The amount of lecithin co-emulsifier in the emulsion can be reduced or this can be completely omitted.

Abstract: The invention relates to an emulsion comprising an aqueous phase and an oil phase having a liposoluble colorant and comprising an emulsifier composition for emulsification of the liposoluble colorant in a foodstuff. In order to further develop the emulsion in such a manner that it has a very high transparency and a stable colouration, and in order to provide an emulsifier composition for a colorant emulsion which also has a high acidic stability in very acidic drinks in the range of pH?3.5, the invention proposes that an emulsifier in the aqueous phase is a quillaia extract and the aqueous phase comprises at least one polyol and/or at least one sugar alcohol and preferably comprises lecithin in the oil phase.
