Why not vegan
Egg = animal product.
What a “Not vegan” verdict means

How to read the label
Egg Yolk 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.
Vegan alternatives

FAQ
- Can I substitute egg yolks in custard?
- Yes — cornstarch + silken tofu or cashew cream produce stable, glossy custards.
- Are backyard or 'ethical' eggs vegan?
- No. Veganism excludes animal products regardless of husbandry standard, though some individuals make personal exceptions.
- What replaces eggs in baking?
- Aquafaba for whipping, flaxseed or chia gel for binding, apple sauce or banana for moisture, and commercial egg replacer for structure.
