Benefits of technology

The invention is a solution for improving the flavor of non-combustion heat smoking articles. The inventors found that adding a specific aerosol generating liquid containing diacetin and monoacetin to the tobacco filler reduced the inhibition of flavor tasting. The tobacco material used in the invention also had a low acetic acid generation rate constant, which further enhanced the flavor experience. Overall, this solution ensures optimal flavor tasting and an improved smoking experience with non-combustion heat smoking articles.

Problems solved by technology

S63-148975 has low boiling point and high vapor pressure, and thus is liable to volatilize in the oral cavity.

[0079]The present invention is more specifically described hereinafter by way of Examples. The present invention may be appropriately modified within the scope of the present invention.

examples 1 and 2

and Comparative Examples 1 to 7: Verification of an Effect by Variation in Aerosol Generating Liquids

[0080]In order to verify an effect of variation of aerosol generating liquids on a reduction of inhibition of flavor tasting, 100 mg of various aerosol generating liquids indicated in Table 1 were respectively added to 100 mg of shredded flue-cured tobacco (product in Japan, hereinafter also merely referred to as shredded tobacco; acetic acid generation rate constant: 1.17×10−8 s−1) as in Example 5 hereinafter as the tobacco material to prepare samples.

[0081]Shredded tobacco used was obtained by grinding tobacco in a household mixer followed by shaking on a sieve (AS 200, manufactured by Retsch GmbH) under the condition: amplitude-1.5 mm / “g” for 2 minutes, and had a mesh size of 0.5 mm or less. The prepared samples were respectively added to a pod dedicated to a product with the product name “Ploom” marketed by Japan Tobacco Inc. so as to be attached to the pod, and stored for 2 days...

and Comparative Examples 8 to 14 Study on the Amount that is Effective for Reduction of Inhibition of Flavor Tasting

[0087]As described above, diacetin and monoacetin are respectively difficult to be isolated, and thus solutions containing diacetin and monoacetin have very similar compositions. Thus, in the following Examples, a solution containing diacetin (commercially available product) was used as a typical example for studying the amount that was effective for reduction of inhibition of flavor tasting.

[0088]In order to study the amount that was effective for reduction of inhibition of flavor tasting, to 100 mg of shredded Burley tobacco (product in Japan), diacetin and, as a comparison, propylene glycol were respectively added at the amounts indicated in Table 2 to prepare samples. The samples were prepared in the same manner as previous Examples and stored for 2 days or more under the conditions of 22° C. and humidity of 60%. The sensory evaluation of the prepared samples was c...

Abstract

The purpose of the present invention is to provide a tobacco filler that can maintain a good smoking flavor and yet reduce “a feeling of lessened smoking flavor” in a non-combustion type heat smoking article served in the form of a tobacco material-containing filler to be heated. Provided is a tobacco filler for a non-combustion type heat smoking article, said tobacco filler containing a tobacco material and an aerosol-forming liquid, wherein the aerosol-forming liquid contains diacetin and / or monoacetin and the acetic acid production rate constant of the tobacco material is 1.25×10−8 s−1 or less.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a Continuation of PCT International Application No. PCT / JP2016 / 071526, filed on Jul. 22, 2016, all of which are hereby expressly incorporated by reference into the present application.BACKGROUND OF THE INVENTIONField of the Invention[0002]The present invention relates to a tobacco filler for a non-combustion type heat smoking article that fills a non-combustion type heat smoking article for use.[0003]In recent years, non-combustion type heat smoking articles that replace cigarettes and allow tasting of a flavor without combusting tobacco have been developed, and one which is a pod-shaped container containing a flavor component and a component capable of generating aerosol filling the container or one having a heat source at a tip thereof are typically known.[0004]It has been also reported that glycerol, triethylene glycol and propylene glycol are added to a filler in such non-combustion type heat smoking articles (see ...
