Guar gum

Guar gum is a thickener milled from the endosperm of the guar bean, Cyamopsis tetragonoloba.

Also on labels: E412 · guaran · guar flour

Guar gum is milled from the seed of the guar bean, a legume, so it is plant-derived and compatible with vegan and vegetarian claims. It is gluten-free, as the bean contains no gluten. Guar is not among the commercially genetically modified crops, so a conventional guar gum is typically non-GMO, though certification still rests on supplier documentation.

What it means for each mark

  • VeganA legume-seed extract with no animal input — compatible with vegan formulations.
  • Gluten-FreeNaturally gluten-free; the concern in a shared facility is cross-contact, not the bean itself.

Where it typically hides

  • Ice cream, dairy and plant-milk products
  • Gluten-free baked goods and doughs
  • Sauces, soups and instant mixes
  • Cosmetics and lotions
  • Pet food and supplements

What a certification review asks for

  1. A botanical-source specification confirming guar bean origin
  2. Shared-line and cross-contact controls where gluten-containing products are also handled
  3. Supplier declaration for any anti-caking or processing aids blended into the grade

Alternatives

  • Xanthan gum (microbial fermentation)
  • Locust bean gum (carob)
  • Konjac and other plant gums
  • Cornstarch for simple thickening

Frequently asked questions

Is guar gum vegan?

Yes. Guar gum comes from the guar bean, a plant, with no animal-derived material, so it is compatible with vegan and vegetarian claims.

Is guar gum gluten-free?

Yes. The guar bean contains no gluten. The only gluten risk is cross-contact in a facility that also handles wheat, barley or rye, which a certification review checks.
