E number system

The E number system is a coding method used in the European Union to identify food additives—substances added to enhance flavor, appearance, or shelf life. Each additive is assigned a unique "E number" (e.g., E100 for curcumin, a yellow colorant). This system helps consumers and regulators recognize approved additives in ingredients lists, ensuring transparency and safety. While common in many processed foods, E numbers indicate additives that have been evaluated for safety, though some consumers prefer to avoid certain additives for health or dietary reasons.
