How to Scan Food Labels for E Numbers: A Complete Guide for 2025
Knowing how to scan food labels for E numbers is vital for anyone concerned about food additives, allergies, or dietary preferences. With food safety regulations evolving in the USA, Italy, and worldwide, understanding E numbers—those short codes for food additives—can help you make informed, healthy choices. This guide, updated for 2025, shows you how to quickly identify E numbers on food labels, explains their significance, and introduces smart tools like Food Scan Genius to simplify the process.
What Are E Numbers?
E numbers are codes assigned to food additives approved for use in the European Union and many other regions. Each E number corresponds to a specific additive, such as a preservative, colorant, or emulsifier. While the USA uses different labeling conventions, many imported foods still display E numbers, and understanding them is crucial for global shoppers.
| E Number | Additive Name | Function | Common Foods |
|---|---|---|---|
| E100 | Curcumin | Color | Curry powders, mustards |
| E200 | Sorbic acid | Preservative | Cheese, baked goods |
| E621 | Monosodium glutamate (MSG) | Flavor enhancer | Snacks, soups |
For a full list of E numbers and their meanings, see the EFSA Food Additives Database.
Why Should You Scan Food Labels for E Numbers?
- Food sensitivities & allergies: Some E numbers are linked to allergic reactions or intolerance.
- Dietary preferences: Vegans, vegetarians, and those avoiding certain chemicals can identify unwanted additives.
- Regulatory differences: Some additives allowed in one country may be restricted or banned in another.
- Health-conscious choices: Recent studies, such as the 2024 PubMed review on food additives and gut health, highlight potential long-term effects of certain E numbers.
Being able to scan and interpret E numbers empowers you to make safer food choices, especially when shopping internationally or online.
How to Scan Food Labels for E Numbers: Step-by-Step
- Locate the ingredients list: On packaged foods in both the USA and Italy, the ingredient list is usually on the back or side. E numbers are often listed alongside their additive names.
- Identify E numbers: Look for codes starting with “E” followed by three or four digits (e.g., E330 for citric acid).
- Check for additive names: In the USA, additives may be listed by name (e.g., “ascorbic acid” instead of “E300”), but imported products often use E numbers.
- Use a food scanner app: Apps like Food Scan Genius allow you to scan barcodes or ingredient lists and instantly flag E numbers of concern.
- Cross-reference with regulatory lists: Regulations differ—what’s allowed in Italy may be restricted in the USA and vice versa. Use trusted sources like the FDA Food Additives Overview and the Italian Ministry of Health Additives Portal.

Comparing Food Labeling: USA vs. Italy
| Feature | USA | Italy (EU) |
|---|---|---|
| Labeling System | Ingredient names, some E numbers on imports | Ingredient names and E numbers required |
| Regulatory Body | FDA | EFSA, Italian Ministry of Health |
| Banned Additives | Some colors/flavors banned or restricted | Stricter on certain preservatives and dyes |
| Allergen Disclosure | Mandatory for top 9 allergens | Mandatory for 14 allergens |
For example, E110 (Sunset Yellow) is permitted in the USA with limits but is subject to stricter controls in Italy and the EU.
