Abstract: A flavoring granule for tobacco products comprising, a solid substrate granule of which comprises natural polysaccharides or derivatives thereof, and a flavor for tobacco products which is contained in said solid granule and is encapsulated in said solid granule so as to be released upon breakage of said solid granule, wherein said solid granule further contains casein as a diluent. Also disclosed is a preparation method thereof, by which the flavoring granule of large size and excellent sphere shape can be obtained.

Abstract: Disclosed is a filter for tobacco smoking which comprises a filter tip having a space therein, with flavor-sealed particles being contained in the space. The flavor-sealing particles are composed of a natural polysaccharide, or its derivative, and diluent agent, and are destroyed, in order to release the flavor sealed therein, by the application of a force to the outer surface of the filter which is greater than a force normally applied to the filter in a smoking action. According to the present invention, the flavor sealed in the particles can be released without the particles being burnt at the time of smoking.

Abstract: The smoking composition referring to the reconstituted tobacco or tobacco substitute and composing of natural tobacco material and/or organic or inorganic material(s), which are combustible as raw materials, and of CMC-Na as binder, is heated at 110.degree.-240.degree. C., preferably at 150.degree.-200.degree. C., desirably for 150-5 minutes, so as to reduce the moisture content thereof to 1% and below. The smoking composition thus heating-processed exhibits a markedly superior water-resistance to the smoking composition not heating-processed, while the former exhibits equal physical properties except water-resistance and organoleptic properties to the latter.
