What Does E412 (Guar Gum) Mean on a Food Label?

When you turn a packet over and see E412, or the words guar gum, on the ingredient list, it is natural to want to know what it is doing there. The answer is simple: it is a natural plant fibre added in tiny amounts to thicken and stabilise food. Here is what that label entry means in everyday terms. For more decoded ingredients, explore our food additives guides.

What the E412 code means

In the European and UK additives system, E-numbers between E400 and E499 cover thickeners, stabilisers, and gelling agents. E412 is specifically guar gum, a soluble fibre ground from the seeds of the guar bean, Cyamopsis tetragonoloba, a legume grown mostly in India and Pakistan. When the code appears on a label, it tells you the maker has added a small dose of this natural gum to control how the product flows and holds together.

Why brands add guar gum

Guar gum is one of the most powerful natural thickeners known. It works even in cold liquids and is several times stronger than cornstarch, so manufacturers need only a tiny amount. As a thickener and stabiliser it:

• Gives ketchup, sauces, and dressings their cling and body.
• Keeps ice cream smooth by preventing ice crystals.
• Holds gluten-free and keto baked goods together where gluten is missing.
• Stops plant milks and yoghurts from separating into liquid and solids.

Is it natural or artificial?

Guar gum is entirely natural, simply the milled inner part of a bean seed. That makes it vegan, vegetarian, gluten-free, and suitable for halal and kosher diets. Its plant origin and very low cost are why it shows up in so many products, especially in the growing gluten-free and dairy-free aisles.

How much is in your food?

EU and UK rules require ingredients to be listed by weight from most to least. Guar gum almost always sits near the bottom of the list, which tells you the amount is very small, usually under half a percent. You will often see it written as thickener (guar gum) or stabiliser: E412.

Often paired with other gums

Guar gum frequently appears beside xanthan gum (E415), locust bean gum (E410), or carrageenan (E407). These gums reinforce one another, so combining them lets a manufacturer use less of each while achieving a smoother, more stable texture. A short list of gums together is a sign of fine-tuned texture, not of low quality.

Should you be concerned about E412?

For everyday foods, no. The European Food Safety Authority reviewed guar gum in 2017 and found no safety concern at the levels used, and the US FDA treats it as Generally Recognised As Safe. Because your body does not absorb it, it adds fibre rather than calories. The only caution is that large dry doses, such as concentrated supplements, should be taken with plenty of liquid, which is irrelevant to the trace amounts blended into food.

In short, E412 on a label simply means your food contains a small amount of natural guar-bean fibre added to improve texture and stop separation, a widely used and well-studied ingredient found across the supermarket.
