Are food additives necessary?

Food additives are necessary in mostly PROCESSED foods, because they preserve the freshness, safety, taste, appearance and texture of processed foods and increase shelf life. Food additives are added for particular purposes whether it is to ensure food safety or maintain food quality during the shelf-life of a product e.g. antioxidants prevents fats and oils from becoming rancid: preservatives prevent or reduce the growth of microbes (e.g. mould on bread); thickeners allow fruit preparations to “gel” so they can be spread onto toasted bread.

Food colorings are used to make food look more attractive. Food additives supply specific sensory properties (e.g. taste and texture) to foods to meet cultural habits and consumer’s expectations. Thickeners, emulsifiers and stabilizers give texture to the food.

Many common foods, such as breakfast cereals and breads, are also fortified with vitamins and minerals that might be lacking in the diet, or they are enriched with nutrients that were lost in the refining process e.g. orange juice are fortified with calcium, to build strong bones in children.
