E481 is one of the most common dough conditioners in industrial baking. It shows up as sodium stearoyl lactylate, sometimes shortened to SSL, and it is the reason a supermarket loaf stays soft for a week. Its halal status rests on a single word in its name: stearoyl.
How E481 is made
Two building blocks are joined. The first is lactic acid, which commercial producers make by fermenting a sugar source such as corn or sugar beet. The second is stearic acid, a saturated fatty acid. The two are reacted together and the product is neutralised with sodium, giving sodium stearoyl lactylate.
The fermentation route for lactic acid is well established and is not usually the sticking point. Stearic acid is another matter. It can be produced from vegetable oils, particularly palm, or it can be rendered from animal fat including tallow. The two routes give the same additive, and the E number is identical either way.
Read more in the stearic acid guide, which covers the same source question wherever it appears on a label.
E481 and E482
You will often see these two together in ingredient lists or discussed in the same breath. E481 is the sodium salt and E482 is the calcium salt. Swapping sodium for calcium changes how the emulsifier behaves in dough. It does not change where the stearic acid came from, so both need the same check.
Why bread needs a full read
Clearing E481 does not clear the loaf. Commercial bread frequently carries more than one source-sensitive ingredient in the same list. L-cysteine, which softens dough, has its own well-known source question. E471 raises the same fatty acid issue as E481. Enzymes used in baking are covered in the enzymes guide. Any of them can be the one that matters.
The halal bread checker walks a loaf label through these together rather than one at a time.
How to check it
- Note whether the label shows E481, E482, or the written name.
- Check for a halal mark and verify it with the certifier for your market.
- Without a certificate, ask the manufacturer for the origin of the stearic acid.
- Read the rest of the bread label for L-cysteine, E471, enzymes, whey, and fats.
What to ask the manufacturer
Please confirm the source of the stearic acid used to produce the sodium stearoyl lactylate in this product. Is it derived from vegetable oil or animal fat, and if animal, from which species? Is this product covered by a current halal certificate in my market?
Frequently asked questions
Is E481 halal?
E481 can be halal. Sodium stearoyl lactylate is built from stearic acid and lactic acid, and the stearic acid may be sourced from plant oils or animal fat. The E number does not record which was used, so certification or a manufacturer answer is needed.
What is E481 used for?
It is a dough conditioner and emulsifier. It strengthens gluten, improves loaf volume, and extends softness, which is why it is common in commercial bread, buns, tortillas, and cake mixes.
What is the difference between E481 and E482?
E481 is sodium stearoyl lactylate and E482 is calcium stearoyl lactylate. The difference is the neutralising mineral. Both are built on stearic acid, so both carry the same source question.
Is the lactic acid in E481 a halal concern?
Commercial lactic acid is normally produced by fermenting a carbohydrate such as corn or beet sugar, so it is not usually the difficult part. The stearic acid is where the animal or plant question sits.
Does E481 contain dairy?
The name lactylate comes from lactic acid, not from lactose or milk. Lactic acid used in this additive is generally made by fermentation rather than taken from dairy, though anyone avoiding milk for allergy reasons should still confirm with the manufacturer.
Is bread with E481 safe to assume is halal?
No. Bread often carries several source-sensitive ingredients at once, including E481, E471, L-cysteine, and enzymes. Check the full list rather than clearing the loaf on one ingredient.
