Abstract: Provided is a taste improver that improves or decreases unpleasant bitterness, astringent taste, harsh taste, bitter taste, or the like that results from potassium salts, magnesium salts, calcium salts, and ammonium salts without adversely affecting savoriness of a food or drink. The taste improver includes a vegetable extract and/or a phospholipid. In the taste improver, the aforementioned vegetable extract includes a vegetable-derived glycoside and/or glycoside aglycone. In the taste improver, the aforementioned phospholipid is phosphatidylcholine, phosphatidylserine, phosphatidylethanolamine, phosphatidylinositol, and/or a lyso form thereof. Arginine is further added to the aforementioned taste improver. Trehalose and/or hydrogenated starch syrup are further added to the taste improver.

Abstract: It is possible to provide an excellent salty taste enhancer is provided that can compensate for insufficient salty taste when attempting to reduce salt content in a food. A salty taste enhancer consisting of a mixture of an enzymatic decomposition product of an animal protein and an enzymatic decomposition product of a plant protein. A salty taste enhancer in which the enzymatic decomposition products are treated with a protein-hydrolyzing enzyme and/or a nucleic acid-hydrolyzing enzyme. A salty taste enhancer in which the animal protein is a fish or shellfish extract and the plant protein is a soy bean protein. A salty taste enhancer in which a basic amino acid, and especially arginine, is further added to the salty taste enhancer. A salty taste enhancer to which potassium chloride is further added. A salty taste enhancer obtained by rendering the salty taste enhancer mildly acidic.

Abstract: 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 a 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.
