Abstract
Amino acids with different functional group show different taste such as bitterness, sweetness and umami. Some of them elicit complicated mixed taste; e. g., L-methionine tastes bitter and sweet simultaneously. A multichannel taste sensor using lipid membranes was applied to amino acids. It was shown that bitter amino acids such as L-tryptophan have response electric patterns similar to a typical bitter substance, quinine, that belongs to alkaloids. The response pattern for L-methionine was found to be similar to that for a mixed solution composed of a sweet amino acid (L-alanine) and bitter amino acid (L-tryptophan). These results agreed quantitatively with human sensory evaluations.
