A soft, chewable and orally dissolvable and/or disintegrable product includes a biopolymer-sugar based matrix and botanical powder dispersed throughout the biopolymer-sugar based matrix. The biopolymer-sugar based matrix includes at least one biopolymer, at least one sugar and optional additives. Soft, chewable and orally dissolvable and/or disintegrable product can also include flavor beads.

Soft, chewable and orally dissolvable and/or disintegrable products

A smoking article having a tobacco rod, which is adapted to produce mainstream smoke, and a filter attached to said tobacco rod. A permeable wrapping paper circumscribes the tobacco rod and the filter. The filter has an upstream end portion and a downstream end portion, and includes a flow restricting segment of smoke impermeable material, which includes at least one open flow passage therethrough to deliver mainstream smoke, and a cavity downstream of the flow restricting segment. The smoking article also includes at least one ventilation zone upstream of the flow restricting segment.

Smoking articles with significantly reduced gas vapor phase smoking constituents

A tobacco rod having reduced levels of at least one phenolic compound precursor selected from the group consisting of gentisic acid, 3,4-dihydroxybenzoic acid, chlorogenic acid, rutin, scopoletin, quinic acid, a quinic acid derivative, caffeic acid, inositol and lignin. The concentration in mainstream smoke of phenolic compounds such as phenol, hydroquinones (e.g., hydroquinone, methyl hydroquinone and 2,3-dimethyl hydroquinone), catechols (e.g., p-coumaryl quinic acid, feruloyl quinic acid and syringoyl quinic acid) and cresols (e.g., o-cresol, m-cresol and p-cresol) can be reduced by reducing the concentration in uncured (e.g., green) or cured tobacco of the phenolic compound precursors. The concentration of phenolic compound precursors in tobacco can be reduced by forming an extract of tobacco solubles, removing phenolic compound precursors from the extract by treating the extract with polyvinylpolypyrrolidone or polyvinylimidazole in the absence of an enzyme to form a treated extract; and restoring the treated extract to the tobacco.
