Abstract
Multi-shelled capsules are made by co-extruding a first liquid flavorant composition and a first shell-forming polymeric material to form droplets which are hardened to form an inner shell containing a first liquid flavorant composition, and then coated with a second shell-forming polymeric material which is hardened to form an outer shell. The result is a capsule where the inner surface of the outer shell is separate and/or separable from the outer surface of the inner shell to define a space, wherein a second liquid flavorant composition may be located.
