Provided herein are pouched products including a chromogenic material or an electronic component, wherein the chromogenic material and the electronic component are responsive to a stimulus. The stimulus may be a change in pH, a change in temperature, or exposure to moisture. Such pouched products can be employed to detect various changes associated with the pouched product.

Stimulus-responsive pouch

The present disclosure provides a method of preparing whitened tobacco composition including chemically pulping a tobacco material to form a tobacco pulp, extracting the tobacco pulp with an extraction solution, treating the tobacco pulp with a solution comprising an oxidizing agent for a time and at a temperature sufficient to lighten the color of the tobacco pulp to give a whitened tobacco pulp, and drying the whitened tobacco pulp to provide the whitened tobacco composition. Alternative bleaching processes and treatment methods effective for preparing whitened tobacco compositions are also provided herein.

Alternative methods for whitening tobacco

Pouch

The disclosure provides a product including a plurality of beads configured for oral use, the plurality of beads containing bleached plant material, a filler, a binder, water, and at least one flavoring agent, active ingredient, or a combination thereof. Further provided are pouched products including the plurality of beads, and a process for preparing the beads.

Beaded tobacco material and related method of manufacture

The disclosure provides oral pouched products including a fleece material with a controlled basis weight. In some embodiments, the oral pouched products may include a material within a porous pouch, wherein the porous pouch includes a fleece material having a basis weight of at least about 35 gsm. In some embodiments, the oral pouched products may include fleece materials have a thickness of at least about 0.2 mm or less than about 0.1 mm. In some embodiments, the pouched products may be configured for rapid or extended release of components contained therein or may be tailored to provide a desired release profile.

Fleece for pouched product with controlled basis weight

The disclosure provides oral products, the oral products including a fleece material that includes fibers and a releasable component. In some embodiments, oral products as described herein may be in the form of a pouchless product including a fleece material having a releasable component associated therewith, or in the form of a pouched product including a fleece material having a releasable component associated therewith in the form of a pouch, containing a substrate material therein.

Fleece for oral product with releasable component

A method of preparing a whitened tobacco material for use in a smokeless tobacco product, including: (i) extracting a tobacco material with an aqueous solution to provide a tobacco solids material and a tobacco extract; (ii) bleaching the tobacco solids material with a solution comprising a strong base, an oxidizing agent, or a combination thereof to provide a bleached tobacco material; and (iii) drying the bleached tobacco material to provide the whitened tobacco material; wherein the tobacco solids material is not subjected to treatment at an elevated temperature with sulfur-containing reagents, organic solvents, sodium hydroxide, or an acid between the extraction and the bleaching.

Method for whitening tobacco

Ribulose-1,5-bisphosphate oxygenase (RuBisCO) protein fibers and a method of producing them are disclosed herein. The method of producing one or more RuBisCO protein fibers including obtaining RuBisCO, tbr example from tobacco, combining the RuBisCO with one or more plasticizers, heating the combination of the RuBisCO and the one or more plasticizers up to about 140 degrees C., filtering the heated combination through an about 20 μm filter, and passing the filtered combination through an orifice to produce one or more RuBisCO protein fibers.

Method of producing ribulose-1,5-bisphosphate oxygenase protein fibers

A method of preparing a whitened tobacco material is provided, including: (i) extracting a tobacco material with a first extraction solution to provide a tobacco solids material and a tobacco extract; (ii) cooking the tobacco solids material in an alkaline cooking liquid comprising sodium sulfide and having a pH of greater than 11 to form a tobacco pulp; (iii) treating the tobacco pulp with an acid to lower the pH of the tobacco pulp and provide a neutralized tobacco pulp; (iv) extracting the neutralized tobacco pulp with a second extraction solution comprising at least one chelating agent to provide an extracted tobacco pulp; and (v) bleaching the extracted tobacco pulp with a bleaching solution to provide a whitened tobacco material.

A method of preparing a whitened tobacco material for use in a smokeless tobacco product is provided, including: (i) extracting a tobacco material with an extraction solution to provide a tobacco solids material and a tobacco extract; (ii) cooking the tobacco solids material in an alkaline sulfite cooking liquor including sulfite ions and having a pH of greater than 7 to form a tobacco pulp; (iii) bleaching the tobacco pulp with a bleaching solution to provide a bleached tobacco material; and (iv) drying the bleached tobacco material to provide the whitened tobacco material.

Ribulose-1,5-bisphosphate oxygenase (RuBisCO) protein fibers and a method of producing them are disclosed herein. The method of producing one or more RuBisCO protein fibers including obtaining RuBisCO, for example from tobacco, combining the RuBisCO with one or more plasticizers, heating the combination of the RuBisCO and the one or more plasticizers up to about 140 degrees C., filtering the heated combination through an about 20 &#x3bc;m filter, and passing the filtered combination through an orifice to produce one or more RuBisCO protein fibers.

RuBisCO protein fibers

The present disclosure relates to cellulose nanomaterials made or derived from tobacco and methods for the production thereof. The tobacco-derived cellulose nanomaterials can be employed in various industrial applications such as film forming applications and solution thickening technologies. In particular, the disclosure is directed to methods for preparing tobacco-derived cellulose nanomaterials using less fibrillation cycles than in the production of wood pulp. The invention includes a method for preparing tobacco derived nanocellulose material comprising receiving a tobacco pulp in a dilute form such that the tobacco pulp is a tobacco pulp suspension with a consistency of less than about 5%; and mechanically fibrillating the tobacco pulp suspension to generate a tobacco derived nanocellulose material having at least one average particle size dimension in the range of about 1 nm to about 100 nm.
