Abstract
Processes for producing flavorful and aromatic compounds from flue-cured tobacco material are provided. The processes involve providing a tobacco suspension comprising finely ground flue-cured tobacco material in intimate contact with ammonia, and subjecting the tobacco suspension to heat treatment for a time and under conditions sufficient to generate a flavorful and aromatic composition. The composition can be applied to smoking articles such as cigarettes to improve the flavor and aroma character thereof.
Claims20
A method for improving the flavor and aroma character in a smoking article comprising:
- providing an aqueous tobacco suspension comprising tobacco material and ammonia, said tobacco suspension having a liquid phase, said tobacco material being flue-cured tobacco, and wherein the ammonia concentration is equivalent to at least about 0.5M ammonium hydroxide;
- subjecting said tobacco suspension to heat treatment for a time and under conditions sufficient to provide a flavorful and aromatic composition;
- and
- incorporating at least a liquid portion of said flavorful and aromatic composition into a component of the smoking article.
A method for improving the flavor and aroma character in a smoking article comprising:
- subjecting an aqueous mixture comprising finely particulate tobacco material and ammonia to heat treatment in a closed elevated pressure, environment at a temperature of at least about 120° C. for a time sufficient to provide a flavorful and aromatic composition, said tobacco material being flue-cured tobacco and said aqueous mixture forming a tobacco suspension wherein the ammonia concentration is equivalent to at least about 0.5M ammonium hydroxide;
- and
- incorporating a portion of said flavorful and aromatic composition into a smoking article containing smokable material.
A method for producing a flavorful and aromatic composition for use in smoking articles, comprising:
- providing an aqueous mixture including finely particulate flue-cured tobacco material and ammonium hydroxide, the aqueous mixture forming a tobacco suspension, and wherein ammonium hydroxide is present at a concentration of at least 0.5M;
- and
- subjecting the aqueous mixture to heat treatment in a closed elevated pressure environment at a temperature of at least about 120° C. for a time sufficient to generate Maillard Reaction products.
