Abstract:
A method of providing a comestible plant material taken orally by coating a micronized plant material (201 ) with a first layer of polysaccharides or proteins, then a second layer of polysaccharides or proteins is disclosed. A bi-encapsulated plant material produced by this process is also disclosed.
Abstract:
Fibrous material suitable for incorporation into filter elements (6) of smoking articles such as cigarettes (2) are impregnated with additives and agents such as flavorants, flavorant-enhancers and/or free radical scavengers. The fibrous material is contacted with the additive dispersed in a high pressure gas or supercritical fluid (SCF) held at elevated pressures. The high pressure gas or SCF swells the fibrous matrix and enables the additive to be incorporated within the matrix. When pressure is reduced, the gas or SCF vaporizes and leaves the additive embedded in the fiber interstices. As a result, the additive is slowly released over a finite period of time. When incorporated into a cigarette filter, the additive is released at a desired rate from the interior of the fibrous filter into the cigarette smoke.
Abstract:
Disclosed is a smoking article containing a rod containing a smokable composition, an optional wrapper for the rod, and at least one polymer or oligomer comprising monomer units of a polycarboxylic acid ester disposed on or in the rod, the wrapper, or both. The polycarboxylic acid ester contains an acid moiety having at least two carboxylic groups, and at least two alcohol moieties independently selected from those corresponding to a cycloalkyi alcohol or an aryl alcohol. The cycloalkyi alcohol or aryl alcohol is a flavorant, or chemesthetic agent, or both. In addition, a method for the controlled release of these flavorant or chemesthetic agents is described, which comprises pyrolyzing at least one polymer or oligomer.
Abstract:
Oral tobacco products (10) having a gel-coating (12) and methods for making are provided. The method includes (a) molding a portion of tobacco material to form a pre-portioned piece of tobacco material (16), the tobacco material comprising moist smokeless tobacco; (b) contacting the pre-portioned piece of tobacco material (16) with a gel-coating solution to form a gel-coating (12) comprising at least one polymer on an outer surface of the pre-portioned piece of tobacco material (16) to form a gel-coated oral tobacco product, said gel- coating (12) comprising an inner surface disposed around the pre-portioned piece of tobacco material (16) and an outer surface; and (c) forming one or more of perforations, uncoated areas and holes (20) in the gel-coating (12) of the oral tobacco product to form a gel-coated oral tobacco product.
Abstract:
Flavorants are emulsified in tobacco-derived lipids and encapsulated with biopolymers and polysaccharides. The emulsions include oil-in-water emulsions, oil-in-water-in-oil emulsions, water-in oil emulsions, or water-in-oil-in-water emulsions, and optionally include ethanol and/or propylene glycol in an oil phase.
Abstract:
Compositions are provided which contain immobilized flavorants, in the form of supramolecular complexes of flavorant compounds, for flavor delivery. One embodiment relates to the flavorant supramolecular complexes themselves. Other embodiments relate compositions which contain the flavorant supramolecular complexes and a substrate. In particular embodiments, the substrate is smokeable, but in other embodiments may be non- smokeable or comestible.
Abstract:
An orally-enjoyable tobacco product (10, 100) includes a portion of smokeless tobacco comprising an active ingredient. The active ingredient is selected from the group consisting of a mercaptan, camphor, borneol, isobomeol, bornyl acetate, isobornyl acetate, mono-bornyl succinate, mono-isobornyl succinate, mono-bornyl formate, and mono-isobornyl formate. The active ingredient is present in an amount effective to reduce or eliminate the sensory irritation arising from the smokeless tobacco. Also disclosed is a method of making such a product.
Abstract:
In one embodiment is provided a polymer blend of poly(vinyl acetate) (PVAc) and poly(acrylic acid) (PAA), wherein the poly(vinylacetate) is present in an amount ranging between about 20 wt% and about 80 wt%, and poly(acrylic acid) is present in an amount ranging between about 80 wt% and about 20 wt%, based on the total weight of the blend. In another embodiment is provided a fiber produced from this polymer blend, and which has cells therein. In another embodiment is provided a flavorant release material comprising the porous fiber disclosed herein, and one or more flavorants disposed in a longitudinally extending core within the fiber. In another embodiment is provided a polymer fiber membrane containing a hollow, porous fiber formed from the polymer blend disclosed herein. In another embodiment is provided a filter containing the fiber described herein. In another embodiment is provided a process for producing the fibers disclosed herein by addition of the polymers to an extruder or blender, and extruding or melt spinning the mixture into a fiber containing cells therein.
Abstract:
A portioned moist tobacco product (10) with a super-hydrated membrane coating (12) and method of manufacturing is disclosed. The super-hydrated membrane coating (12) is formed by ionic cross-linking using two polymers. The soluble component of the super-hydrated membrane coating (12) dissolves upon placement in the mouth, while the insoluble component maintains the tobacco (16) within the coating for the duration of the use of the product (10). The moist tobacco product (10) is soft and flexible so as to fit comfortably in an oral cavity when placed therein.
Abstract:
Delivery of additives in a smoking article (200) is provided through thermally degradable, robust immobilized additive inserts (100). Additives can be immobilized in an elongated device (110) or an insert, wherein the elongated device (110) or the insert is sufficiently robust to allow the elongated device (110) or the insert to be manually or machine inserted into a smoking article (200) while maintaining the structure of the elongated device (110) or the insert. By providing additives in the form of thermally degradable immobilized additive inserts (100), migration and/or loss of the additives in a smoking article (200) prior to smoking can be reduced.
