Allergens in peanut butter

Peanut butter is peanuts. Peanuts are an allergen in their own right — they are not tree nuts. Emphasise peanut. Some brands add soya lecithin or sugar; the peanut is always there.

The usual pattern

Crunchy and smooth are the same allergen. Powdered peanut butter used in protein pots is still peanut. Satay sauce built on peanut butter is peanut plus whatever else is in the sauce.

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

Peanuts, salt.

Where it shows up

Satay, cookies, flapjacks, smoothie pots and some vegan sauces.

Peanut and tree nuts on one line

Do not write nuts for peanuts. The customer avoiding cashews and the customer avoiding peanuts are not the same person. Name peanut.

A peanut-free sunflower-seed butter is not a like-for-like label. Change the ingredients list.

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.

Questions

Are peanuts tree nuts?
No. Peanuts are legumes. UK labels emphasise them separately from almonds, cashews and the other named nuts.
Does a small swirl of peanut butter count?
Yes. If it is in the recipe, peanut is an ingredient.
