Patent ID: 8409653

Claim:
A method for enhancing a salty taste, comprising adding (a) a synthetic compound of a dipeptide selected from the group consisting of Glu-Ala, Glu-Arg, Glu-Asn, Glu-Asp, Glu-Gln, Glu-Glu, Glu-Gly, Glu-His, Glu-Ile, Glu-Pro, Glu-Ser, Glu-Thr, Glu-Trp, Glu-Val, Arg-Glu, Asp-Glu and His-Glu, and (b) at least one selected from the group consisting of an enzymatic decomposition product of a protein and a basic amino acid to a common salt-containing food or drink, wherein the synthetic compound of a dipeptide is added in an amount sufficient to enhance the salty taste of the common salt contained in the food or drink as compared to that of a food or drink in which the dipeptide is not added, and wherein each of Glu-Ala, Glu-Arg, Glu-Asn, Glu-Asp, Glu-Gln, Glu-Glu, Glu-Gly, Glu-His, Glu-Ile, Glu-Pro, Glu-Ser, Glu-Thr, Glu-Trp, Glu-Val, Arg-Glu, Asp-Glu and His-Glu has a sequence order from the carboxyl terminal end to the amino terminal end.
