Claim Text:
1. A method for encapsulating a liquid flavorant composition in a multi-shelled capsule, comprising: (a) co-extruding a first liquid flavorant composition and a first shell-forming polymeric material to form a core-shell droplet; (b) hardening the first shell-forming polymeric material of the droplet to form an inner shell around an inner core, the inner core comprising the first liquid flavorant composition; (c) coating the inner shell with a coating layer comprising a second shell-forming polymeric material; and (d) hardening the second shell-forming polymeric material by contacting the second shell-forming polymer with polyvalent metal ions present in or on the inner shell, to form an outer shell of the multi-shelled capsule, wherein the co-extruding step comprises using a co-extruder comprising an inner nozzle having a diameter of between about 0.5 mm and 2 mm, and an outer nozzle having a diameter of between about 1.5 mm and 3 mm, and wherein the first liquid flavorant composition is fed to the inner nozzle at between about 40 mbar and 80 mbar, and the first shell-forming polymeric material is fed to the outer nozzle at between about 100 mbar and 130 mbar.
