  • Publication number: 20250031713
    Abstract: 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.

  • Patent number: 12178221
    Abstract: Disclosed herein are chewing gum compositions having fat polymorphs that are predominantly beta prime and/or beta over alpha. Also disclosed are methods of forming chewing gum compositions having predominantly beta prime and/or beta fat polymorphs which have sufficient textural properties to be processed into wrapped/packaged chewing gum products or coated to coated chewing gum products. Improved methods of forming and conditioning chewing gum to reduce costs, cut down on conditioning time, and to improve gum sensory properties are disclosed.

  • Publication number: 20220104534
    Abstract: 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.

  • Patent number: 9687023
    Abstract: A moist smokeless tobacco product for oral use comprises a pre-portioned piece of tobacco material semi-dissolvable, a super-hydrated membrane coating comprising a soluble, non-cross-linked component and an insoluble, cross-linked component, and a texture component.
