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.
Additives that are added to a food for a specific purpose are known as direct additives. For example, the low calorie sweetener, aspartame, is a direct additive that is added to puddings, soft drinks, yogurt, and many other foods. Direct additives are identified on a foodâs ingredient label. Artificial or synthetic colors and flavors are examples of this type of additive. 2  These additives are added in minute amounts that can have a large impact. 3  By FDA regulations, colorings can only be used to enhance visual appeal, not to misrepresent the food (Jones 1992).
