Control release mentholated tobacco beads

摘要

Encapsulated tobacco beads and processes of making the encapsulated tobacco beads are disclosed. According to an embodiment, a process of making encapsulated tobacco beads comprises mixing tobacco particles and menthol in an aqueous solution to form a wet mass; extruding the wet mass to form extrudates; spheronizing the extrudates to form tobacco beads; drying the tobacco beads; contacting the beads with a solution comprising a cation; and introducing the contacted tobacco beads into a solution of coating material in a concentration effective to induce ionic gelation of the coating material around the beads, to form encapsulated tobacco beads having gel coatings. According to another embodiment, an encapsulated tobacco bead comprises a core comprising tobacco particles and encapsulated menthol, an inner coating layer comprising hydroxypropyl methylcellulose or pectin, and an outer coating layer comprising an ionically-crosslinked gel.
