Xanthan
/ˈzæn.θən/noun
A yellowish polysaccharide used as a thickening and stabilizing agent.
Did you know?Xanthan gum got its name from Greek *xanthos* (“yellow”), the same ancient color-root behind words like *xanthic* and *xanthophyll*—so this “modern” food additive is secretly built on a very old color-word.
