What E410 actually is
Locust bean gum thickens without making things gluey, and its real trick is working alongside carrageenan and xanthan to produce textures neither achieves alone. It is what stops ice cream growing ice crystals in the freezer and gives cream cheese its body. The name is misleading: no locusts are involved, and it comes from the carob tree.
What it is made from
Ground endosperm of seeds from the carob tree, a Mediterranean evergreen. Entirely plant-derived, with no chemical modification.
Vegan, vegetarian, and halal status
Locust bean gum is plant-derived and suits vegan, vegetarian, and halal diets. Two questions come up repeatedly and both have clear answers. It contains no gluten, because carob is not a cereal grain. And carob is botanically a legume, so people with a diagnosed legume allergy, particularly to peanut, occasionally react; that is uncommon but real and is worth knowing if you have one.
Is E410 safe?
Locust bean gum is permitted with no numerical intake limit in the EU, UK, and US, and it is one of the few thickeners permitted in infant formula, which is the strictest category any additive faces. It is a soluble fibre, so it is not absorbed. EFSA re-evaluated it in 2017 and raised no safety concern at reported intakes.
- A soluble fibre, so large amounts can cause bloating or a laxative effect
- Carob is a legume, so a small number of people with legume allergy react
- Contains no gluten; carob is not a cereal grain
- Permitted in infant formula, which reflects a high confidence threshold

Common questions
- Is locust bean gum a legume?
- Yes. Carob is botanically a legume, which is why a small number of people with legume allergy react to it. That is uncommon but real.
- Does locust bean gum have gluten?
- No. Carob is a tree seed, not a cereal grain, so there is no gluten at any stage.
- Is locust bean gum made from locusts?
- No. It comes from the seeds of the carob tree. The name is a historical misnomer.
- Is locust bean gum vegan and halal?
- Yes. It is a plant seed extract with no processing that introduces animal material.
- Why is it always with other gums?
- It works synergistically with carrageenan and xanthan, producing textures none of them achieves alone. That is why ingredient lists often show two or three gums together.
