    摘要： Methods of modifying the tobacco-specific nitrosamine content of a tobacco material are described herein. One exemplary method comprises contacting a tobacco material with a composition comprising salt, sugar, enzyme, lactic acid bacteria, yeast, or a combination thereof to reduce the total bacterial content; curing the tobacco material; and fermenting the tobacco material in the presence of one or more microorganisms. The method can provide a fermented tobacco material having a tobacco-specific nitrosamine content that is reduced relative to a fermented tobacco material that has not been subjected to the disclosed method steps. In certain embodiments, the tobacco-specific nitrosamine content of the fermented tobacco material is no more than that of the cured tobacco material. Tobacco-containing products including such treated tobacco materials are also provided.

    摘要翻译： 本文描述了改变烟草材料的烟草特异性亚硝胺含量的方法。 一种示例性方法包括使烟草材料与包含盐，糖，酶，乳酸菌，酵母或其组合的组合物接触以降低总细菌含量; 固化烟草材料; 并在一种或多种微生物存在下发酵烟草材料。 该方法可以提供具有烟草特异性亚硝胺含量的发酵烟草材料，其相对于未经过公开的方法步骤的发酵烟草材料而减少。 在某些实施方案中，发酵烟草材料的烟草特异性亚硝胺含量不超过固化烟草材料的含量。 还提供了包括这种经处理的烟草材料的含烟草制品。

    摘要： Methods of fermenting a tobacco material and methods of modifying the total bacterial content of a tobacco material are provided herein. One example method includes treating a tobacco material with superheated steam in a pressurized vessel to provide a steam-treated tobacco material having a reduced total bacteria content and fermenting the steam-treated tobacco material in the presence of one or more microorganisms to provide a fermented tobacco material. In some embodiments, the methods provided herein can provide a fermented tobacco material having a tobacco-specific nitrosamine content that is reduced relative to a fermented tobacco material that has not been subjected to the disclosed method steps and/or a modified flavor or aroma profile relative to a fermented tobacco material that has not been subjected to the disclosed method steps.
