Food Additives. Food additives are substances added intentionally to foodstuffs to perform certain technological functions, for example to colour, to sweeten or to help preserve foods. In the European Union all food additives are identified by an E number. Food additives are always included in the ingredient lists of foods in which they are used.
Color additives are blended to create a brightness or intensity to the base color. The other basic ingredients of synthetic food coloring are propylparaben, propylene glycol and water. Used in medicines and cosmetics as well as food coloring, propylene glycol is classified as a food additive.
