Abstract

The present invention provides an odorant composition having good palatability allowing peoples to feel comfortable using a small number of chemical compounds. An odorant composition according to an embodiment of the present invention consists of: when the total mass of ingredients contained in the odorant composition is 100.0% by mass, 40.0% by mass or more and 97.5% by mass or less of an ingredient (A) composed of aldehydes; 1.0% by mass or more and 20.0% by mass or less of an ingredient (B) composed of a ketone(s); and the balance being an ingredient (C) composed of a chemical compound(s) other than the ingredient (A) and the ingredient (B). The aldehydes of the ingredient (A) are: an essential ingredient (A1) composed of nonanal; and an optional ingredient (A2) selected from the group consisting of decanal, heptanal, octanal, benzaldehyde, undecanal, hexanal, and combinations thereof. The ketone(s) of the ingredient (B) is selected from the group consisting of 6-methyl-5-hepten-2-one, cyclohexanone, 1-phenylethanone, 2-decanone, 2-undecanone, and combinations thereof. The chemical compound(s) of the ingredient (C) is selected from the group consisting of limonene, 1,8-cineole, menthol, 1-octanol, 3-hexyn-1-ol, 2-nonen-1-ol, dodecane, hexanoic acid, octanoic acid, nonanoic acid, 2(5H)-furanone, p-cymene, sotolon, and combinations thereof.
