摘要： A method of modifying the content of certain chemical compounds in tobacco materials is provided, the method including treatment of a tobacco plant or portion thereof with at least one enzyme. For example, the method may modify the content of tobacco smoke toxicant precursors in tobacco materials, which can result in a modification in toxicant production when the tobacco material is exposed to elevated temperatures. The type of tobacco plant or portion thereof treated according to the invention can be, for example, a tobacco seed, a tobacco seedling, an immature live plant, a mature live plant, a harvested plant, or a plant derivative. Smoking articles and other tobacco products including such enzyme-treated tobacco materials are also provided.
摘要翻译： 提供了一种改变烟草材料中某些化合物含量的方法，该方法包括用至少一种酶处理烟草植物或其部分。 例如，该方法可以改变烟草材料中烟草烟毒物前体的含量，这可能导致当烟草材料暴露于升高的温度时毒物生产的改变。 根据本发明处理的烟草植物或其部分的类型可以是例如烟草种子，烟草幼苗，未成熟的活的植物，成熟的活的植物，收获的植物或植物衍生物。 还提供了包括这种酶处理的烟草材料的吸烟制品和其它烟草制品。

摘要： A method of preparing a smoke-treated tobacco material is provided, the method including the steps of: (i) subjecting a tobacco material to smoke to give a smoke-treated tobacco material with modified taste characteristics; and (ii) incorporating the smoke-treated tobacco material into a smokeless tobacco product. The invention also provides a smokeless tobacco product incorporating a smoke-treated tobacco material. The smokeless tobacco product may be, for example, a moist snuff tobacco product.

摘要： A method of modifying the content of certain bacteria in uncured tobacco material is provided, the method including contacting an uncured tobacco material with a treatment solution, wherein the treatment solution is selected from the group consisting of: (i) a solution comprising salt, sugar, or a combination thereof; (ii) a solution comprising one or more enzymes; and (iii) a solution comprising one or more probiotics, wherein said contacting provides a treated tobacco material having a reduced total bacterial content following harvest. In certain embodiments, the treated tobacco material is subsequently cured, and can optionally be fermented. Smoking articles and smokeless tobacco products including such treated tobacco materials are also provided.

摘要： A method of modifying the content of certain chemical compounds in tobacco materials is provided, the method including treatment of a tobacco plant component with at least one probiotic. For example, the method may modify the asparagine content in tobacco materials, which can result in a modification in acrylamide production when the tobacco material is exposed to elevated temperatures. The type of tobacco plant component treated according to the invention can be a tobacco seed, a tobacco seedling, an immature live plant, a mature live plant, a harvested plant, or a portion thereof. Examples of probiotics include probiotic species of the genera Bifidobacterium, Lactobacillus, Enterococcus, Proionobacterium, Bacillus, Saccharomyces, Streptococcus, and mixtures thereof. Smoking articles and other tobacco products including such probiotic-treated tobacco materials are also provided.

摘要： A flue-curing apparatus and a related method are provided. The flue-curing apparatus includes a circulation chamber and a curing chamber that are separated by a divider wall. An air circulation system includes a blower positioned in the circulation chamber that directs air to a heater device and a lower passage into the curing chamber. The air may be received from one or both of an inlet and an upper passage extending from the curing chamber to the circulation chamber. A humidity control system humidifies the air directed into the curing chamber. A controller may receive signals from wet and dry bulb thermometers to determine the conditions in the curing chamber and the condition of tobacco leaves being cured therein. The controller may adjust various operational parameters to cause the tobacco leaves in the curing chamber to cure at a desired rate.
