Food additives have been used for centuries to improve and maintain the taste, texture, nutrition and appearance of foods. Food additives and preservatives make it possible to prevent foodborne diseases and to transport foodstuff where it is otherwise impossible and to improve product efficiency to consistently meet established quality standards between products It is used for today's food supply to enable production.
