A method for producing a tobacco flavor liquid, the method comprising:
- obtaining a tobacco component-containing liquid by extracting a component from a starting tobacco material using an organic solvent;
- and
- obtaining a tobacco flavor liquid with an increased concentration of a tobacco component-derived ester compound by (i) mixing the tobacco component-containing liquid with an aqueous solution comprising a basic substance and an alcohol in an oxygen-containing atmosphere, and (ii) reacting the tobacco component-containing liquid with the aqueous solution in the mixture,
- wherein the organic solvent included in the tobacco component-containing liquid is immiscible with the aqueous solution.
A method for producing an ester compound, the method comprising:
- obtaining a tobacco component-contain liquid by extracting a component from a starting tobacco material using an organic solvent;
- and
- obtaining a tobacco flavor liquid with an increased concentration of a tobacco component-derived ester compound by reacting the tobacco component-containing liquid with an aqueous solution comprising a basic substance and an alcohol in an oxygen-containing atmosphere;
- and
- separating the ester compound from the tobacco flavor liquid,
- wherein the organic solvent included in the tobacco component-containing liquid is immiscible with the aqueous solution.
