Allergens in lactose-free milk
Lactose-free milk is still milk. The lactose has been broken down. The milk protein is still there, so a PPDS food made with it must emphasise milk. Lactose-free is not a dairy-free claim.

The usual pattern
The carton is cow’s milk treated with lactase. It behaves like milk in a sauce or cake. Oat, soya and almond drinks are not lactose-free milk — they are different allergens.
What to check in lactose-free milk
| What you see | What it means on a PPDS label |
|---|---|
| Lactose-free cow’s milk | Milk |
| Lactose-free cheese or yoghurt | Milk |
| Oat drink | Oats, not milk |
| A dairy-free recipe | No milk emphasis only if no dairy milk is used |
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
Lactose-free milk.
Where it shows up
Custards, white sauces, cakes and porridge aimed at lactose intolerance.
Dropping milk from the label
The words lactose-free on the carton do not remove milk from the ingredients list. Emphasise milk.
A medical question about tolerance is for the customer and their clinician. The label states the allergen.
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.
