概要	This study examined whether adding xanthan gum (X) alters chorda tympani nerve responses and preference for coffee in male Wistar/ST rats. Electrophysiological recordings showed that mixtures of coffee and X produced larger nerve responses than expected from individual components. In a 48-h two-bottle test, rats consumed a coffee–xanthan gum mixture significantly more than xanthan gum alone, despite coffee’s bitterness. These results suggest that xanthan gum enhances both gustatory nerve responses and preference for coffee in rats.
