摘要:
A method for improving the flavor and aroma characters of a smoking article is provided. A mixture consisting essentially of a reducing sugar and optionally a hydroxide of an alkali metal is subjected to heat treatment for a time and under conditions sufficient to produce a flavorful composition. The flavorful composition is then applied to tobacco leaves or cut filler made thereof, and smoking articles are prepared from the tobacco leaves or cut filler.
摘要:
Improved flavorful and aromatic tobacco materials and a method for producing flavorful and aromatic components from all natural tobacco materials are provided. A first tobacco material is contacted with a second tobacco material to form a tobacco blend. The first tobacco material has a higher content of nitrogen source and a lower content of sugar source than the second tobacco material. The moisture content in the first and second materials of the tobacco blend is increased to at least about 20%. The tobacco blend having an increased moisture content is then subjected to heat treatment in a substantially atmospheric environment for a time and under conditions sufficient to generate flavorful and aromatic substances in said first and second tobacco materials.
摘要:
A method for providing flavorful and aromatic substances for use in a smoking article is disclosed. In the method, a mixture is provided including a reducing sugar source and a base catalyst. The mixture has a selectively enriched content of at least one free amino acid selected from the group consisting of serine, threonine, valine, leucine, and isoleucine. The mixture is then subjected to heat treatment for a time and under conditions sufficient to provide a flavorful and aromatic composition
摘要:
This invention provides a method for improving the flavor and aroma properties in a smoking article. A high fructose corn syrup, ammonium hydroxide and diammonium phosphate are reacted with each other for a time and under conditions sufficient to provide a heat activatable flavorant-generating composition, which comprises 2-deoxy 2-amino glucose. The composition is incorporated into a component of said smoking article without heat treatment. The resultant smoking articles, when smoked, exhibit highly desirable flavor and aroma properties.

The present invention provides a method for producing plants with a desired phenotypic trait which comprises subjecting plants to mutagenesis, screening chimeric progeny for plants having the desired phenotypic trait, and propagating the survivors. In an embodiment, the phenotypic trait comprises an altered amino acid content. Preferably, the technique is used to generate Nicotiana tobacum plant lines having an increase in at least one amino acid. In a preferred embodiment, the invention provides improved Nicotiana tobacum plant lines producing at least 1.35 nmole of threonine per milligram of dry plant weight. These plants are useful for improving the flavor and aroma of the tobacco.

摘要:
A tobacco composition for use in a smoking article or a smokeless tobacco composition is provided, the composition including a component derived from a seed of the Nicotiana species. The component can be a seed of the Nicotiana species or a portion thereof in particulate form or in the form of seed isolate derived from a seed of the Nicotiana species. In certain embodiments, the seed isolate is in the form of a chemically transformed seed isolate, the chemical transformation being selected from hydrogenation, acid/base reaction, hydrolysis, thermal treatment, and enzymatic treatment. The invention also provides smoking articles and smokeless tobacco compositions that include the seed components described herein, and methods for preparing a component derived from a seed of the Nicotiana species for addition to a tobacco composition.
