Abstract: Provided is a coolant for heat-not-burn tobacco, which comprises a polyhydric alcohol and a porous granular base material, wherein the polyhydric alcohol is impregnated into the granular base material.

Abstract: The present invention addresses the problem of providing a filter for a smoking article that can reduce a stimulus component such as formaldehyde, and that does not reduce any more than necessary a component affecting the smoke flavor included in mainstream smoke. This problem is solved by providing a smoking article filter comprising a filter segment that has a porous material containing: a hydrotalcite particle; and a nonfibrous binder resin.

Abstract: The present invention addresses the problem of providing a filter for a smoking article, or the like, which does not reduce, more than necessary, components affecting flavor which are contained in mainstream smoke, and which does not release aroma components other than an aroma component which is attributable to tobacco smoke. The foregoing problem is solved by a filter for a smoking article, the filter comprising a filter segment which does not release aroma components and which has a porous material that includes: inactive particles which do not selectively reduce components contributing to flavor with respect to raw tar in tobacco smoke; and a non-fibrous binder resin.

Abstract: Provided are: a smoking product that has a tobacco rod and a filter comprising granular activated carbon, wherein the lightness L* value of said granular activated carbon in the CIE Lab color space is 11.50-19.00 and the acetone adsorption capacity is 29.0-41.0% percentage by mass; a method for producing said smoking product; and a method for distinguishing granular activated carbon.
