A method of isolating compounds from a tobacco-derived black liquor, including receiving a black liquor from a pulping process of an input material comprising a plant of the Nicotiana species, treating the black liquor with an acid to lower the pH of the black liquor to about 7 or lower in order to produce a precipitate and an acidified black liquor, separating the precipitate and the acidified black liquor, extracting the acidified black liquor with an organic solvent in order to produce an organic layer extract and an aqueous layer extract, and separating the organic layer extract and the aqueous layer extract.

The invention provides a slow-release fragrance and an application thereof in a tobacco product with Chinese-style flavor. The slow-release fragrance of the invention includes the following constituents in percentage by mass: 5% to 50% of a tobacco extract and 50% to 95% of a tangerine peel extract.

An aerosol generating substrate comprising an aerosol generating material, wherein the aerosol generating material comprises an amorphous solid, the amorphous solid comprising 1-60 wt % of a gelling agent; 5-80 wt % of an aerosol generating agent; and 1-70 wt % of an active ingredient; wherein these weights are calculated on a dry weight basis; wherein bi-modal or multi-modal release of one or more active ingredients of the amorphous solid is observed in use.

An aerosol generating article for use in an aerosol generating assembly, the article comprising an aerosol generating substrate comprising an aerosol generating material, wherein the aerosol generating material comprises an amorphous solid, the amorphous solid comprising: 1-60 wt % of a gelling agent; 5-60 wt % of an aerosol generating agent; and 10-60 wt % of a tobacco extract; wherein these weights are calculated on a dry weight basis.

An aerosol generating assembly comprising an aerosol generating substrate and a heater which is configured to heat but not burn the aerosol generating material. The aerosol generating substrate comprises an aerosol generating material, the aerosol generating material comprising an amorphous solid. The amorphous solid comprises 1-60 wt % of a gelling agent, 0.1-50 wt % of an aerosol generating agent, and 0.1-80 wt % of a flavor, wherein these weights are calculated on a dry weight basis.

An aerosol-generating amorphous solid comprising an active ingredient, wherein when a sheet of the aerosol-generating amorphous solid having an area of 43.1 mm.sup.2 and area density of 90 g/m.sup.2 is heated to 230° C. for a period of 3 seconds under a 1.1 L/min airflow, at least 50 wt % of the active ingredient is aerosolized.

Reconstituted cannabis is prepared by processing cannabis plant material by breaking it down into small particles to form a pulp. Water, starch and other materials are added, and the moisture content of the resulting slurry is adjusted to about 50%. This viscous slurry is then applied to a perforated steel belt using high power sprayers to form a sheet. The sheet is dried and additional additives such as nicotine, flavorings and liquid removed from the slurry are added to the sheet. The resulting reconstituted cannabis formed is homogenous and contains evenly distributed CBD and nicotine. The reconstituted cannabis sheets may be cut into small particles for use as cigarette or cigar filler. The reconstituted cannabis, in the form of sheets or particulate matter, may also be incorporated into oral pouches, chewable products, edible products, vaporizer additives and as a carrier for CBD and nicotine for transdermal patches.
