A smokeless tobacco composition for oral use comprising liberated, delignified tobacco fibers, a method for its manufacturing and use, as well as a pouch comprising the composition.

A process for production of bleached tobacco raw material comprising: (I) mechanically defibrating uncooked tobacco raw material to produce a defibrated tobacco raw material; and (II) treating the defibrated tobacco raw material with at least one bleaching agent to produce a treated tobacco raw material.

Embodiments also include bleached tobacco raw material obtainable by the process.

This document provides methods and systems for stabilizing nicotine and incorporating nicotine into one or more oral products. This document also provides oral products. Nicotine can be stabilized by mixing nicotine with a silicon oxide-containing porous solid such that the nicotine absorbs into pores of the porous solid to form a porous solid-nicotine mixture. In some cases, a porous solid-nicotine mixture can be combined with one or more binders and molded into an oral product.

The present invention relates to an improved method for preparing a tobacco composition suitable for use as a smokeless tobacco composition wherein the tobacco material can be cooled down, after being heated to a temperature of 80 C. or more, to a temperature of below 25 C. during a time period of 20 min or less.

The present document generally relates to methods and materials involved in producing tobacco or smokeless tobacco product comprising chlorate. For example, chlorate can be used to reduce tobacco specific nitrosamine content in tobacco or smokeless tobacco products.

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.

An oral tobacco composition in which sensations to the throat and esophagus that are characteristic of raw tobacco are selectively removed, and a production method thereof are provided. Provided is an oral tobacco composition in which the ratio of total content of one or more of citric acid, malic acid, succinic acid, acetic acid and formic acid to the nicotine content (A/N) is 1.30 or less.

A heated aerosol-generating article is provided, including an aerosol-forming substrate including tobacco and a metal-based sulphide scavenger compound, an amount of a metal component of the sulphide scavenger compound in the aerosol-forming substrate is at least 0.05 percent by weight, based on a total dry weight of the aerosol-forming substrate, and the sulphide scavenger compound is based on a transition metal.

Methods of making reconstituted tobacco include contacting a mixture including tobacco pulp with one or more fluid streams including one or more peroxides (e.g., hydrogen peroxide), recovering one or more fluids from the tobacco pulp mixture, and reusing the recovered fluids in at least one subsequent tobacco pulp contacting step. In some cases, methods provided herein can recover one or more fluids including one or more peroxides, such that the at least one subsequent tobacco pulp contacting step includes contacting tobacco pulp with a fluid including one or more peroxides.

The present invention relates to a composition comprising nicotine and/or nicotine salt, and calcium silicate, wherein the composition is in a pouch, wherein the pouch is intended to be placed in the mouth.
