The invention relates to a temperature-resistant formulation which contains a water-soluble natural coloring agent and is provided in the form of a water-in-oil emulsion that contains the coloring agent in the aqueous phase, the coloring agent being stable at elevated temperatures, e.g. at a minimum temperature of 72 °C. The coloring agent can be thermally unstable at the pH of the food into which the formulation is mixed. |
