When Dinner Turns Into a Dilemma: A Parent’s Story
Last month, Sarah, a mother of two in Chicago, prepared her family’s favorite pasta dinner. Within an hour, her youngest developed red patches and an upset stomach. The culprit? A hidden food additive, listed cryptically as “E621.” Like many, Sarah found herself asking: How to know if food contains E numbers?
Understanding E Numbers: What Are They?
E numbers are codes for substances used as food additives within the European Union and other regions. Each E number represents a specific additive—such as preservatives, colorants, or flavor enhancers—approved for use in foods. The system, managed by the European Food Safety Authority (EFSA), aims to standardize labeling and ensure consumer safety.[1]
- E100–E199: Colors
- E200–E299: Preservatives
- E300–E399: Antioxidants, acidity regulators
- E400–E499: Thickeners, stabilizers
- E500–E599: Acidity regulators, anti-caking agents
- E600–E699: Flavor enhancers
- E900–E999: Miscellaneous (sweeteners, glazing agents)
In the United States, additives are listed by their chemical names, but many are identical to those covered by E numbers.[2]
Why Should You Care About E Numbers?
For consumers with food allergies, sensitivities, or dietary restrictions, knowing whether a product contains certain E numbers is essential. Some additives have been linked to adverse reactions in sensitive individuals, especially children.[3] Recent news coverage by The New York Times and BBC Health highlights growing public concern about transparency in food labeling.
- Allergies: Some E numbers (e.g., E220, sulfites) can trigger reactions.
- Dietary Preferences: Vegetarians and vegans may wish to avoid animal-derived additives (e.g., E120, carmine).
- Health Risks: Ongoing research investigates links between certain additives and hyperactivity or other health issues.[4]
How To Know If Food Contains E Numbers? (Step-by-Step Guide)
Identifying E numbers in packaged foods requires careful label reading and, increasingly, digital tools. Here’s how you can find out:
- Read the Ingredient List: In the EU, additives are listed by their E numbers (e.g., E621). In the US, look for chemical names (e.g., monosodium glutamate for E621).
- Check for Allergen Information: Both the FDA and EFSA require disclosure of major allergens and certain additives.
- Use a Food Scanner App: Apps like Food Scan Genius let you scan barcodes and instantly see if a product contains specific E numbers or allergens.
- Consult Official Lists: Both FDA and EFSA publish lists of approved additives and their codes.
| Feature | United States (FDA) | European Union (EFSA) |
|---|---|---|
| Additive Labeling | Chemical name (e.g., Monosodium Glutamate) | E number (e.g., E621) |
| Allergen Disclosure | Mandatory for major allergens | Mandatory, with additional requirements |
| Ingredient Transparency | Required, but less standardized | Highly standardized, including E numbers |

Scientific Insights: Are E Numbers Safe?
Both the FDA and EFSA rigorously assess food additives before approval. Most E numbers are considered safe within established limits, though ongoing research examines long-term effects.[5]
- EFSA Review: Regularly updates safety assessments (EFSA Food Additives).
- FDA Guidance: Publishes additive safety and allergen information (FDA Food Additives).
- Recent Studies: PubMed research links some additives to behavioral changes in sensitive children (PubMed Study).
News outlets like The Guardian report on evolving regulations and consumer advocacy for clearer labeling.
