If you have ever looked at a European food label, you have likely seen E-numbers — codes like E100, E330, or E621. These are standardized identifiers for food additives approved for use in the European Union and many other countries.
What Do E-Numbers Mean?
E stands for "Europe." Each number corresponds to a specific additive: colors (E100–E199), preservatives (E200–E299), antioxidants (E300–E399), emulsifiers (E400–E499), and so on. Not all E-numbers are harmful — vitamin C is E300, and pectin (a natural thickener) is E440.
E-Numbers Generally Considered Safe
- E300 (Ascorbic acid) — Vitamin C, used as an antioxidant.
- E440 (Pectin) — Natural fiber from fruit, used as a gelling agent.
- E322 (Lecithin) — Emulsifier from soy or eggs, generally well tolerated.
- E500 (Sodium bicarbonate) — Baking soda, completely safe in normal amounts.
E-Numbers to Approach with Caution
- E102 (Tartrazine) — Yellow dye linked to hyperactivity in sensitive children.
- E211 (Sodium benzoate) — Preservative that may form benzene when combined with vitamin C.
- E621 (Monosodium glutamate) — Flavor enhancer; sensitivity reported by some consumers.
- E951 (Aspartame) — Artificial sweetener with ongoing debate about long-term effects.
Scan Instead of Memorize
Memorizing hundreds of E-numbers is impractical. Vital Scan decodes ingredient labels instantly, explaining what each additive does and whether it aligns with your health preferences.
