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.

A process for preparing coated tobacco particles suitable for usage in a smokeless tobacco product, comprising:
- (a) combining finely-divided particles of tobacco with one or more proteins in a liquid medium, under conditions effective to adsorb the protein onto at least a portion of a surface of the finely-divided particles of tobacco to form a first layer;
- and
- (b) mixing one or more polysaccharide compositions comprising a pectin and a carrageenan with the liquid medium under conditions effective to adsorb at least some of the pectin onto at least a portion of a surface of the first layer to form a second layer, to form a coacervate of coated particles of tobacco and a depleted liquid medium,
- wherein the resulting coacervate of coated tobacco particles has a color lighter than raw tobacco and when placed in the mouth are capable of swelling upon contact with saliva to provide a pleasant in-mouth feel and the release of tobacco flavor.
A coated tobacco particle suitable for use in a smokeless tobacco product, comprising:
- a base tobacco particle;
- a first layer at least partially coating the base particle, the first layer comprising a protein;
- and
- a second layer at least partially coating the first layer, the second layer comprising a polysaccharide composition including a pectin,
- wherein the resulting coated tobacco particle has a color lighter than a raw tobacco particle and when placed in the mouth upon is capable of swelling upon contact with saliva to provide a pleasant in-mouth feel and a release of tobacco flavor.
A process for preparing coated tobacco particles suitable for usage in a smokeless tobacco product, comprising:
- combining finely-divided particles of tobacco simultaneously with one or more proteins and with one or more polysaccharide compositions comprising a pectin in a liquid medium, under conditions effective to adsorb the protein onto at least a portion of a surface of the finely-divided particles of tobacco to form a first layer, and effective to adsorb at least some of the pectin onto at least a portion of a surface of the first layer to form a second layer, to form a coacervate of coated particles of tobacco and a depleted liquid medium,
- wherein the resulting coacervate of coated tobacco particles has a color lighter than raw tobacco and when placed in the mouth are capable of swelling upon contact with saliva to provide a pleasant in-mouth feel and the release of tobacco flavor.
