  • Patent number: 10334874
    Abstract: Methods for producing dissolving grade pulp and microcrystalline cellulose from tobacco are provided. The methods include chemical pulping a tobacco input to form a tobacco pulp. Chemical pulping the tobacco input includes combining the tobacco input with a strong base defining a weight from about 5% to about 50% of the tobacco input, and heating the tobacco input and the strong base with an H-factor from about 500 to about 3,300. Further, the methods include bleaching the tobacco pulp to produce a dissolving grade pulp. Bleaching the tobacco pulp may include chlorination of the tobacco pulp with a chlorine dioxide solution, and caustic extraction of the tobacco pulp with a second strong base. A related tobacco-derived microcrystalline cellulose product is also provided, which can be used as a binder, a filler, and/or a texturizer in a tobacco product, such as a smokeless tobacco product.

  • Patent number: 10321708
    Abstract: 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.

  • Patent number: 10258079
    Abstract: A smoking article, such as a cigarette, includes a carbonaceous heat source. A mouth end piece segment is located at the mouth end of the smoking article, and the mouth end piece segment allows the smoking article to be placed in the mouth of the smoker to be drawn upon. The smoking article further incorporates an aerosol-generating segment located between the heat generation segment and the mouth end piece segment. The aerosol-generating segment incorporates an aerosol-forming material (e.g., glycerin and flavors). The heat generation segment is in a heat exchange relationship with the aerosol-generating region such that heat generated by the burning fuel element acts to volatilize aerosol-forming material for aerosol formation. The carbonaceous heat source is in intimate contact with coarse, fine or ultrafine particles of materials such as cerium oxide, or mixtures of cerium oxide and palladium chloride.

  • Publication number: 20190093119
    Abstract: Methods and compositions are provided for increasing the expression of a gene of interest in a plant by co-expressing the gene of interest with a p21 polynucleotide. The gene of interest can be endogenous or heterologous to the plant. Further provided are plants, such as tobacco plants, comprising a heterologous p21 polynucleotide. Co-expression of the p21 polynucleotide with a gene of interest in the plant increases the expression of the gene of interest when compared to a control plant. Accordingly, p21 co-expression can increase the expression of genes of interest encoding proteins such as defense proteins, enzymes, signaling proteins, reporter proteins, antibodies and fragments thereof, growth factors, cell surface receptor molecules, seed storage proteins, and fungicides in a plant.
