Abstract

Food additives is a food preservation solution which involves exposes foodstuffs to a source of energy capable of stripping electrons from individual atoms in the targeted material (ionizing radiation). This method of food preservation can be referred to as a more advanced form of food preservation. Some school of thought criticize the use of additives for food preservation because of the negative impressions of the nuclear industry, and this has made additives one the most investigated forms of food preservation. Food additives has being endorsed by the World Health Organization (WHO), and is currently being used in over 40 countries and approximately 500,000 tons of food items are irradiated yearly all over the world. This work has highlighted some problems associated with the use of food additives in Nigeria, and has also proffered solutions that can help tackle the said problems. This work has also discussed the process of food additives, the recommended sources and the dose range required for effective additives of food products.
