Allergens in lupin flour
Lupin flour is lupin, one of the 14 allergens. It turns up in some pastries, waffles and gluten-free or high-protein bakery mixes, including products bought in from continental suppliers. If the mix contains lupin, the PPDS label must emphasise it.

The usual pattern
Lupin is a legume. The flour is pale and easy to mistake for soya or chickpea flour. Only the specification tells you which one arrived.
What to check in lupin flour
| What you see | What it means on a PPDS label |
|---|---|
| Lupin flour | Lupin |
| Chickpea flour | Not lupin, and not an Annex II allergen |
| Soya flour | Soya, not lupin |
| Mixed bakery improvers | May include lupin without it being obvious from the recipe name |
How to write it on the label
PPDS food needs the name of the food and a full ingredients list, with the 14 allergens emphasised every time they appear. The Food Standards Agency’s PPDS guidance is the practical reference. A typical ingredients fragment looks like this — yours must follow the specification of the product you actually use.
Example fragment
Lupin flour.
Where it shows up
Some baguettes, waffles, gluten-free blends and protein breads.
A bought-in pastry
Lupin is more common in imported bakery than in a standard UK plain flour. Check the ingredient statement on the box, not the local recipe.
Someone allergic to peanuts is sometimes also sensitive to lupin. That is a clinical point. Your job is to emphasise lupin when it is an ingredient.
Specification first
Brands differ. Treat this page as the usual pattern, then match the label to the tub, bag or recipe in front of you.
