What a “Depends” verdict means
A 'depends' verdict means the same ingredient name covers both plant and animal sources, and the label alone cannot tell you which one is in the tub. Certification, an allergen statement, or a direct answer from the manufacturer is the only reliable way to settle it.

How to read the label
Mayonnaise belongs to the egg derivatives family. These are the terms worth scanning for on any ingredient list in this category:
- Albumen
- Albumin
- Ovalbumin
- Globulin
- Livetin
- Lysozyme
- Vitellin
- Egg wash
- Meringue
- Read the allergen statement — egg must be declared on packaged food.
- For bakery counters, ask specifically about egg wash and brioche-style enriched dough.
- Lysozyme (E1105) in hard cheeses and some wines is egg-derived.
- Check 'protein' ingredients in fitness food: egg-white protein is common.
Mistakes to avoid
| Where it catches people out | What to do |
|---|---|
| Fresh pasta | Almost always egg-based in Italy; dried pasta is usually just semolina and water. |
| Shiny bread crust | Egg wash is standard for glossy finishes. Vegan bakeries use plant milk or aquafaba. |
| Marshmallow and nougat | Uses egg white or gelatine for aeration, sometimes both. |
Egg derivatives in context
Egg appears in processed food as three separate functional ingredients: whole egg for structure, albumen for foam and binding, and lecithin or lysozyme derived from yolk and white for emulsifying and preservation.
Egg is a declarable allergen in the EU, UK and US, so like dairy it cannot be hidden — but the technical names are unfamiliar enough that people miss them when skimming. Albumin, globulin, ovalbumin, vitellin and lysozyme are all egg.
Egg-washed baked goods are the biggest practical gap, because a glaze brushed on a pastry may be declared only in a general allergen note or, in unpackaged bakery goods, not written down at all.
Does certification help? A vegan trademark is the fastest confirmation, but for packaged food the mandatory allergen box is already conclusive for egg content.
