Embodiment 1

[0058] A mixture of flavorant (9670-102A) in vegetable oil was fed through the internal nozzle or nucleating nozzle (1.0 mm diameter) of a Brace GmbH Spherisator 2002 Mark II 1410-087 coextruder at a pressure of 55 mbar. A 2% by weight aqueous solution of sodium alginate (first shell-forming polymeric material) was supplied through the outer nozzle or shell-forming nozzle (2.5 mm diameter) of the coextruder at a pressure of 100 mbar. The vibration frequency is 80 Hz, and the vibration amplitude is 350 mV. The coated cores produced by coextrusion were contacted with an aqueous hardening solution containing 5% by weight calcium chloride and filtered, washed with additional aqueous hardening solution containing 5% by weight calcium chloride. A portion of the coated cores produced are undesirably small "satellite" capsules (which can be screened out or separated from desired capsules) or have cores that are not perfectly centered. A small amount of oil was observed on the surface...

Embodiment 2

[0061] The procedure above in Example 1 was generally followed except that the flavorant was supplied through the inner nozzle at a pressure of 60 mbar and the alginate solution was supplied through the outer nozzle at a pressure of 125 mbar. A portion of the coated cores produced were satellite shaped or had cores that were not perfectly centered. After drying, several capsules burst. The weight of the capsules is about 30 mg to about 35 mg per capsule, with an average weight of about 32 mg / capsule. The burst strength of the capsules was measured and found to be from about 3.5N to about 16.7N.

Embodiment 3

[0063] The procedure described in Example 1 was generally followed except that the vibration frequency was 100 Hz and the external nozzle pressure was 105 mbar. Few small capsules were observed, but several unencapsulated globules were observed. To an aqueous solution containing 0.25% by weight sodium alginate and 1.0% by weight polyvinylpyrrolidone ("PVP"), the filtered coated cores were added, stirred for 20 minutes, diluted with water, removed from the solution, and left without adding Filter directly under the condition of more calcium chloride. As in Example 1, the filtered capsules were dried in a tumble dryer. The average capsule weight was found to be 33.8 mg / capsule, but PVP did not prevent aggregate formation.

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.

Description

Background of the invention [0001] Flavorants, such as compounds and compositions that provide pleasing taste and aroma to other products, are often incorporated into consumer products, such as smoking and smoke-free products, to enhance their sensory enjoyment. However, certain flavorants are prone to volatilization, escaping during storage and before the product is used. [0002] Accordingly, it would be desirable to reduce or reduce the migration and loss of flavorants in consumer products, especially tobacco products such as smoking articles and smokeless tobacco, so that the consumer receives a greater percentage of the applied flavorant even after the product has been stored for a period of time. edible spices. Additionally, it would be desirable to provide flavorants to consumer products in a manner that enables the application and control of the release profile of multiple flavorants to provide the consumer with a continuum of enjoyable experiences.
