Abstract
In order to formulate natural dyes, which are insoluble or sparingly soluble in water, in such a way that the dye is protected against oxidation, also and in particular after being incorporated into the end product with dilution, and which as a replacement for azo dyes in a beverage result in a solution which is clear to the human eye, the invention provides a solubilizate and a method for preparing a solubilizate. The solubilizate contains at least one natural dye that is insoluble or sparingly soluble in water, at least one emulsifier having an HLB value of 8 to 19, and at least two antioxidants. The dye and the antioxidants are present enclosed together in micelles.
