It is possible to provide an excellent
salty taste enhancer that can compensate for insufficient
salty taste when attempting to reduce the
salt content of food. A
salty taste enhancer obtained by adding a
glutamic acid, containing
dipeptide, specifically, Glu-Ala, Glu-Arg, Glu-Asn, Glu-Asp, Glu-Gln, Glu-Glu, Glu-Gly, Glu-His, Glu-Ile, Glu-Leu, Glu-Lys, Glu-Pro, Glu-Ser, Glu-Thr, Glu-Trp, Glu-Tyr, Glu-Val, Arg-Glu, Asn-Glu, Asp-Glu, Gln-Glu, His-Glu, Pro-Glu, Ser-Glu, Thr-Glu or Trp-Glu to an enzymatic
decomposition product of a
protein material and / or a basic
amino acid, especially
arginine. A method for producing these salty taste enhancers, a method for enhancing a salty taste by using these salty taste enhancers, and a food or drink that contains these salty taste enhancers.
