US Classification:

426 96, 426271, 131354, 131370

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.

International Classification:

A24B 15/40

US Classification:

131275, 131310

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.
