Abstract
Abstract Active ingredients useful in chewable articles of commerce are physically encased in non-porous, chewable, particles of elastomer and such particles are then incorporated in the articles of commerce. During mastication of the chewable article of commerce the active ingredient is released from the elastomer particles over a prolonged period of time. The active ingredients would include flavorants, intense sweeteners, colorants, medicaments, effervescent agents and tobacco.
