Abstract
The bitter taste of L-valine, L-tryptophan, L-trileucine and a tryptic hydrolysate of alpha(s1)-casein was diminished to 17-35% of its origi nal strength by glutamic acid in a molar excess between 0.6 and 14. Th e bitter taste of compounds from other structural classes was not (nar ingin, limonin) or not seriously affected by glutamic acid. The maxima l effects were decreases in bitterness to 77% (caffeine) and 71% (quin ine) of the original value, respectively. The results indicate the exi stence of various bitter receptors.
