Abstract (en)

[origin: EP2989907A1] The present invention provides a tobacco raw material having a good smoking flavor and a method for producing the same. Provided is a tobacco raw material having a ratio, which is expressed as "water-extracted material weight/hexane-extracted material weight," between the weight of an extracted material obtained by extraction using n-hexane as a solvent and the weight of an extracted material obtained following the extraction by further extraction using water as a solvent, of 0 or more and 1.5 or less.
