Various embodiments are directed to consumable products incorporating a matrix of cultured tobacco cells. Any tobacco variety may be utilized for establishing in vitro tobacco cultures, including native tobacco varieties and genetically modified tobacco varieties derived from any tobacco variety. Various embodiments are directed to methods for producing tobacco products incorporating cellular material and/or extracts derived from tobacco cells cultured in vitro.

Cultured tobacco cells as a matrix for consumable products

A facility and method steps for air curing tobacco in an enclosure include hanging the tobacco in the enclosure-having at least one vertically arranged air duct positioned in a central portion of the enclosure, at least one in-line fan positioned in a vertical portion of the at least one vertically arranged air duct, at least one ventilating fan located in an upper portion of the enclosure and at least one openable and closeable opening in at least one side wall of the enclosure. The humidity within the enclosure is lowered by opening the openable and closeable openings in at least one side wall of the enclosure and forcing warm air from the top of the enclosure down through the tobacco within the enclosure by operating the ventilation fans located in a top portion of the enclosure. Humidity is raised within the enclosure by closing the openable and closeable side openings and introducing water or other aqueous solutions into the vertical air ducts while operating the in-line fans within the air ducts to diffuse the moisture and drive it upwards for warming and uniform distribution throughout the barn.

Tobacco is treated before or during curing to lower or eliminate bacterial populations and/or activity, fungal growth, and/or tobacco-specific nitrosamine or bacterial endotoxin levels in the cured tobacco, wherein the tobacco is treated with an effective amount of a wash solution. Air-cured tobacco may be cured in four weeks or less when treated with a wash solution of bicarbonate salts.
