Nutrient supplements in food and beverage chemicals are added to enhance nutritional value, fortify products with essential vitamins and minerals, or replace nutrients lost during processing. Common supplements include vitamins (A, D, B-complex, C), minerals (calcium, iron, zinc), amino acids, omega-3 fatty acids, and fiber. These additives help address dietary deficiencies, improve health benefits, and cater to functional food trends. They must comply with safety regulations (e.g., FDA, EFSA) to ensure proper dosage and bioavailability without compromising taste or shelf life. Examples include fortified cereals, vitamin-enriched drinks, and protein-fortified snacks.
