Abstract: There is provided a method for producing a yeast extract containing an organic acid, especially succinic acid, at a high concentration, and further containing glutamic acid at a high concentration. There is provided such a production method comprising an organic acid generation treatment step of maintaining a suspension of cultured yeast under conditions effective for organic acid generation to increase organic acid content in the yeast; and a hot water extraction step of extracting a yeast extract from the yeast that has undergone the organic acid generation treatment step at 56° C. or higher.

Abstract: The present invention provides agent for enhancing egg aroma comprising at least one component(s) as an ingredient selected from the group consisting of: (a) 3-(methylthio)1-propanol, (b) benzaldehyde, (c) 4-heptanol, (d) trimethylpyrazine, (e) methylpyrazine, or (f) 2,5-dimethylpyrazine. The agent of the present invention is used for enhancing egg aroma, especially an egg flavor, of an egg product. The examples of preferred egg products to which the present invention is applied include, but not limited to, a boiled egg itself, various food products using a boiled egg (for example, tartar sauce, prepared bread filling, and so on), various food products containing an egg as a component (for example, mayonnaise, dressing, pasta sauce, Japanese omelette, steamed egg custard, steamed egg hotchpotch, omelette, quiche, rolled omelette, noodles, fried rice, custard cream, pudding, cake, sponge cake, ice cream, egg (custard) tart, bread, crape, and so on).

Abstract: The present invention relates to a method for enhancing salty taste-like taste of food and drink, as well as providing a seasoning composition and a salty taste-like taste enhancer to be provided to the method. The present invention provides a seasoning composition including a 5?-ribonucleotide and a branched-chain amino acid; the seasoning composition and the salty taste-like taste enhancer containing 0.45 to 81 parts by weight of the branched-chain amino acid relative to 100 parts by weight of the 5?-ribonucleotide; and a method for enhancing salty taste-like taste of food and drink containing 2 to 90 parts by weight of the 5?-ribonucleotide and 0.05 to 9 parts by weight of the branched-chain amino acid.

Abstract: An agent for improving the eating quality of chocolate products is disclosed; it comprises as an active ingredient a yeast extract comprising (a) free glutamic acid in an amount of at least 10 wt % (preferably at least 15%) as calculated for sodium glutamate, (b) disodium 5?-inosinate and disodium 5?-guanylate in a total amount of at least 1 wt % (preferably at least 1.5 wt %), and (c) 2-furanmethanol and/or 5-methyl-2-furanmethanol.

Abstract: There are provided a method by which the acrid taste and/or metallic taste of potassium chloride which is added to food compositions for the purpose of manufacturing low- or reduced-salt products is suppressed in a safe and economical manner without compromising the palatability of the food compositions, as well as an agent for use in this method to suppress the acrid taste and/or metallic taste derived from potassium chloride. The agent contains a yeast-derived peptide containing composition as the active ingredient. The invention is also useful for salt reduction and for the treatment of diseases or conditions that are associated with excessive salt intake, as well as diseases or conditions that can be improved by reducing salt intake.
