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.
