Biscuits, called cookies in some markets, are consistent enough as a category that one reading method covers most of the aisle. Two ingredients do most of the work.
The fat
Biscuit texture comes from fat. The label may name it precisely, as in palm oil or sunflower oil, or it may use a general term. Vegetable fat and vegetable oil are plant derived and answer the question. Fat, shortening, and animal fat do not, and the shortening guide covers why that word names a job rather than a source.
The emulsifier
Almost every commercial biscuit carries one. The two most common are soya lecithin, which is normally plant derived, and E471, which carries the fatty acid source question that runs through the whole emulsifier family.
Resolve the fat and the emulsifier and you have covered the majority of a plain biscuit label.
Fillings, coatings, and glazes
- Cream fillings: more fat and more emulsifier, sometimes with whey or milk solids.
- Chocolate coatings: covered in the chocolate guide, including lecithin, whey, and flavourings.
- Glazes: a shine on a biscuit may come from egg, sugar, or a glazing agent, and shellac is one of those.
- Marshmallow or jelly layers: these bring gelatin into the product.
- Colours: decorated and iced biscuits are worth checking for carmine.
How to check it
- Find the fat and see whether the label names it as vegetable.
- Find the emulsifier and note whether it is lecithin or a numbered code.
- Read fillings and coatings as separate products with their own lists.
- Look for gelatin in anything with a marshmallow or jelly layer.
- Check any shine for a glazing agent.
The halal E number checker will identify every code on the pack at once, and the cake guide covers sweet bakery more broadly.
Frequently asked questions
Are biscuits halal?
They can be. The two ingredients that carry most biscuit labels are the fat and the emulsifier, both of which may be plant or animal derived without the label saying which. Fillings and coatings add further questions.
What fat is used in biscuits?
Commonly palm oil or another vegetable fat. Where the label says only vegetable fat, that is plant derived. Where it says fat, shortening, or animal fat, the source needs confirming.
Which emulsifier appears most often?
E471, mono- and diglycerides of fatty acids, along with soya lecithin. Lecithin is normally plant derived; E471 carries a fatty acid source question.
Do cream-filled biscuits need extra checking?
Yes. Fillings add more fat and emulsifier, and sometimes whey or milk solids, so a filled biscuit has more to read than a plain one.
What about chocolate-coated biscuits?
The coating carries its own questions, including emulsifiers, whey, and sometimes a glazing agent for shine.
Is L-cysteine used in biscuits?
L-cysteine is more common in bread than in biscuits, but it appears in some doughs. It is worth recognising because its source question is well known.
