Embodiment Construction

[0022] Introduction

[0023] The following description and examples further illustrate the preferred embodiments of the present invention. Those of skill in the art will recognize that there are numerous variations and modifications of this invention that are encompassed by its scope. Accordingly, the description of preferred embodiments should not be deemed to limit the scope of the present invention.

[0024] In preferred embodiments, methods and compositions for delivering menthol or other flavorants into the smoke stream of a smoking article, such as a cigarette, are provided. The method involves microencapsulation of the flavorant and incorporation of the microcapsules into the smoking article. The microcapsules isolate the flavorant from adsorbents, such as activated charcoal, and provide for the controlled release of the flavorant during smoking, as well as provide for a longer shelf life for the smokable article than is possible when unencapsulated flavorants are present. The sh...
