Colourants are often more desirable options due to their comparatively cleaner image among the common consumeferrous fumarate zincrs. However, these natural and nature-identical colourants are notoriously susceptible to degradation in an aqueous environment triggered by external factors such as heat, light or pH changes. Furthermore, due to strict regulatory requirements in the food industry, there are only a limited number of colourants approved for food use. Hence, more often than not, to obtain the desired colour shade, food formulators have to rely on the blending of differemolecular weight of ferric pyrophosphatent colours together.
