Food additives are substances added to food to preserve flavor or enhance its taste, texture, and appearance. With the advent of processed foods many more additives are being used, both natural and artificial. Additives can maintain product quality and freshness (to stop deterioration, rancidity, and spoilage); improve or maintain the nutritional quality (to prevent diseases such as goiter, pellagra and rickets); make foods more appealing (make them look and taste good); and aid in the processing and preparation of foods.
