摘要:
Fibrous material suitable for incorporation into filter elements of smoking articles such as cigarettes 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.
摘要:
A process for preparing an orally-enjoyable film of encapsulated plant material includes combining particles of finely divided plant material, a first coating material, and a second coating material, then inducing gelation to form a gel matrix of the particles coated with the first coating material embedded in the second coating material, followed by forming a film from the gel matrix. Also disclosed is a film of coated particles of finely-divided plant material, made of a gel matrix of plant material at least partially surrounded by a first coating material and embedded in a second coating material.
摘要:
A smokeless tobacco product includes a plurality of orally disintegrable granules. Each granule has a lipid core and at least one layer surrounding the core. The core can also include binders, powdered tobacco carbohydrates, water soluble polymers, flavorants, salts, sweeteners, and combinations thereof. The orally disintegrable granules can provide a pleasing texture and/or flavor experience.
摘要:
Oral tobacco products having a gel-coating 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, the tobacco material comprising moist smokeless tobacco; (b) contacting the pre-portioned piece of tobacco material with a gel-coating solution to form a gel-coating comprising at least one polymer on an outer surface of the pre-portioned piece of tobacco material to form a gel-coated oral tobacco product, said gel-coating comprising an inner surface disposed around the pre-portioned piece of tobacco material and an outer surface; and (c) forming one or more of perforations, uncoated areas and holes in the gel-coating of the oral tobacco product to form a gel-coated oral tobacco product.
摘要:
Delivery of additives in a smoking article is provided through thermally degradable, robust immobilized additive inserts. Additives can be immobilized in an elongated device or an insert, wherein the elongated device or the insert is sufficiently robust to allow the elongated device or the insert to be manually or machine inserted into a smoking article while maintaining the structure of the elongated device or the insert. By providing additives in the form of thermally degradable immobilized additive inserts, migration and/or loss of the additives in a smoking article prior to smoking can be reduced.
摘要:
A smokeless tobacco product includes smokeless tobacco and structural fibers. The structural fibers forming a network in which the smokeless tobacco is entangled. The structural fibers have a composition different from the smokeless tobacco. The tobacco-entangled fabric can have an overall oven volatiles content of at least 10 weight percent. In some embodiments, the structural fibers form a nonwoven network. In some embodiments, fibrous structures of the smokeless tobacco are entangled with the structural fibers.
摘要:
A process for preparing coated particles of a plant material includes: (a) combining plant material particles and a protein in a liquid medium, wherein the protein adsorbs onto at least a portion of a surface of the particles to form a first layer; and (b) mixing a polysaccharide including a pectin with the liquid medium, so that the polysaccharide adsorbs onto at least a portion of a surface of the first layer to form a second layer. In addition, a palatable product comprising at least one coated particle prepared by this process is described.
摘要:
Compositions are provided which contain immobilized flavorants for flavor delivery. In particular, smoking compositions are provided which contain flavorant ester salts of polycarboxylic acids.
摘要:
A continuous process for the preparation of linear, branched and star-polymers via anionic polymerization of acrylic monomers, linear, branched and star-polymers obtained by the process and lubricating oil compositions thereof.
摘要:
The present invention relates to the product(s) of the polymerization of specific combinations of acrylic monomers, and optionally vinyl and/or performance enhancing comonomers, in the presence of an anionic initiator to form copolymers having a narrow molecular weight distribution. Additionally, the invention relates to the use of these copolymers as pour point depressants in lubricating oil formulations.
