EXTRACTION METHOD OF FLAVOR CONSTITUENT AND MANUFACTURING METHOD OF COMPOSITION ELEMENT OF FAVORITE ITEM

摘要

An extraction method of a flavor constituent comprises: a step A for heating a tobacco raw material which is subjected to an alkali treatment; and a step B for bringing a release component released in the gas phase in the step A into contact with a collection solvent at normal temperature until any time from when a first condition is satisfied to when a second condition is satisfied. The first condition is determined based on a residual rate of nicotine component. The second condition is determined based on a remaining amount of nicotine component.

1. An extraction method for extracting a flavor constituent from a tobacco raw material, comprising:
a step A for heating a tobacco raw material which is subjected to an alkali treatment; and a step B for bringing a release component released in the gas phase in the step A into contact with a collection solvent at normal temperature until any time from when a first condition is satisfied to when a second condition is satisfied, wherein the first condition is a condition that a remaining amount of nicotine component which is an index of the flavor constituent contained in the tobacco raw material decreases until reaching 1.7 wt % in the case where the weight of the tobacco raw material in the dry state is 100 wt %, or is a condition that a residual rate of the nicotine component decreases until 40% in the case where the weight of the tobacco raw material is 100 wt %, and the second condition is a condition that the remaining amount of the nicotine component contained in the tobacco raw material decreases until reaching 0.3 wt % in the case where the weight of the tobacco raw material in the dry state is 100 wt %.
