E415 - Xanthan gum
By the Daat team · Updated October 30, 2026
E415, xanthan gum, is a thickener made by bacterial fermentation of sugar.
A tiny amount turns a liquid thick, which is why sauce and dressing makers love it. The biggest share of its uses in our catalog is exactly there.
Gluten-free bakers know it well: it replaces some of the stretch that gluten gives dough.
816 products in our catalog contain E415, or 4.8% of those with an ingredient list. Most of them are sauces, spreads and salads and cakes, biscuits and pastries.
