  • Publication number: 20110083681
    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.

  • Publication number: 20110083688
    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. The tobacco material comprises moist smokeless tobacco. The texture component reduces the slipperiness and/or increases the friction of the moist smokeless tobacco product when placed in a user's mouth.

  • Publication number: 20100303969
    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.

  • Publication number: 20090197792
    Abstract: The present disclosure is directed to acidic cleaning compositions comprising 1 to 9% by weight of a layered phyllosilicate in surface modified sodium or protonated forms and pre-dispersed in pre-gel form with and without additives, 1 to 5% of an anionic surfactant, 2-10% of a hydrotope, 0.1-15% solvents, and at least one organic or inorganic acid as a pH-adjusting agent to provide a composition having a pH less than about 4.0. The compositions provide improved viscosity profile, sprayability, and drip resistance when applied to vertical surfaces.

  • Publication number: 20090197790
    Abstract: The present disclosure is directed to both sprayable and non-sprayable cleaner compositions comprising 1 to 9% by weight of a layered phyllosilicate, 1 to 10% of a surfactant, and at least one silicate salt or strong base as a pH-adjusting agent. The composition optionally can include hypochlorite bleach and the pH of the formulation can be in the range 11 to 14. The composition optionally can include water-insoluble glycol ether type solvents or oils in the form of emulsions or microemulsions for degreasing, disinfecting, and fragrance delivery. The compositions provide improved drip resistance when sprayed on to vertical surfaces.
