Potentiometric analysis of bitterness in Euclidian distances [t(1)] (see Supplementary Fig. 12 for details). a Bitterness response of denatonium (De; structure a), structure b (D-methyl), structure c (D-(G)1), structure d (D-(G)4), and structure e (K-D). Values were normalized to plain buffer responses. All experiments were performed with n = 3. b Prototype of the compressed chewing gums. Scale bar length equals 1 mm
