Why not vegan
Cream is dairy.
What a “Not vegan” verdict means
A not-vegan verdict means the ingredient is animal-derived in essentially all commercial supply, so a product listing it should be treated as non-vegan unless the manufacturer explicitly states a plant-based source in writing.
Where you'll find it

How to read the label
Sour Cream belongs to the dairy derivatives family. These are the terms worth scanning for on any ingredient list in this category:
- Casein
- Caseinate
- Whey
- Lactose
- Lactalbumin
- Lactoglobulin
- Milk solids
- Ghee
- Curds
- Recaldent
- Read the bolded allergen statement first — dairy cannot legally hide there.
- Treat any word starting with 'lact-' or containing 'casein' as dairy until proven otherwise.
- 'Non-dairy' is a marketing term in the US and legally permits caseinate; 'dairy-free' and 'vegan' are stronger.
- Check 'may contain milk' lines if cross-contamination matters to you.
Mistakes to avoid
| Where it catches people out | What to do |
|---|---|
| Non-dairy creamer | Frequently contains sodium caseinate, a milk protein. Choose an oat or soy creamer instead. |
| Vegan-styled cheese with stretch | A handful of 'plant-based' cheeses still use casein for melt. Look for a vegan trademark. |
| Crisps and savoury snacks | Whey powder is a standard flavour carrier even in vegetable flavours. |
Dairy derivatives in context
Milk is fractionated industrially into dozens of components — proteins, sugars, minerals and fats — each of which gets a technical name that does not contain the word 'milk'. This is why dairy is the single most common accidental slip for new vegans.
Dairy fractions are cheap functional ingredients: casein binds, whey adds protein and browning, lactose carries flavour, and milk minerals adjust texture. They turn up in products that have nothing to do with dairy, including bread, crisps, processed meat analogues and even some 'dairy-free' cheeses that use casein for stretch.
The good news is legal: in the EU, UK and US, milk is a declarable allergen, so any dairy fraction must be highlighted in bold, capitals or an explicit 'Contains: milk' statement. Reading the allergen line is faster and more reliable than reading the whole ingredient list.
Does certification help? Because dairy is a labelled allergen, an explicit 'Contains: milk' line is decisive. A vegan trademark also excludes dairy processing aids, which allergen law does not cover.

FAQ
- Is crème fraîche vegan?
- No — it is cultured cream and falls in the same category.
- Is lactose-free the same as dairy-free?
- No. Lactose-free products are still made from cow's milk with the lactose enzymatically broken down, so they are not vegan.
- Does 'may contain milk' make a product non-vegan?
- It is a cross-contamination warning, not an ingredient. Most vegans still buy these products; it is a personal threshold.
