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.

A film comprising:
- encapsulated plant material including,
- a plant material particle;
- a first coating at least partially surrounding the plant material particle, the first coating including a protein, cationic polysaccharide, cationic oligosaccharide, non-ionic polysaccharide, non-ionic oligosaccharide, or any combination thereof, the first coating included in an amount ranging from 1% to 20% by dry weight;
- and
- a second coating surrounding the first coating and the plant material particle, the second coating being a gel matrix that includes an ionic, a zwitterionic, a neutral material, a protein, or any combination thereof, the second coating included an amount ranging from 5% to 50% by dry weight, the film having a textured surface and being mouth-stable for 1 minute to 20 minutes.
