Nutrients in food can be lost during processing and cooking, making it necessary to supplement foods with additional nutrients to enhance their nutritional value. Food nutrient additives are substances used specifically to fortify or replenish the nutritional content of foods. Any food additive that improves the quality of food can be classified as a quality improver. Quality improvers serve various functions, such as retaining moisture, preventing caking, promoting leavening, emulsifying, thickening, improving texture, regulating acidity, enhancing sweetness, preserving color, maintaining freshness, and providing antioxidant benefits.
