Food colours

Some factors that influence the decision to use a natural dye, and that are related to the main challenges in its use, are:

 • Higher cost than its synthetic equivalent.

 • Colour stability and its dependence on factors such as ph, temperature, light exposure and

 Oxidation reactions with other ingredients.

 • Color uniformity during food processing and storage.

 • Durability of colour and alteration of taste during food storage.

 • Harmlessness and health benefits attributed to some natural pigments
