Flavor capsules for smoking articles

Abstract

A smoking article includes a smokable material and a filter downstream of the smokable material. The filter comprises a capsule having a core and a breakable shell. The core has a mixture including one or more lipid compounds and one or more humectants. The lipid compounds account for 50% or more of the weight of the mixture. At least one of the one or more humectants is capable of interacting with one or more smoke constituents to reduce the concentration of the one or more smoke constituents in mainstream smoke.

Description

technical field

[0001] The present disclosure relates to smoking articles having a filter comprising a frangible capsule containing one or more smoke components capable of interacting with one or more smoke components to reduce mainstream smoke concentration of the compound. Background technique

[0002] Combustible smoking articles, such as cigarettes, typically have cut tobacco, usually in the form of cut filler, surrounded by a wrapper to form a tobacco rod. A smoker uses a cigarette by lighting one end of the cigarette and burning the tobacco rod. The smoker then receives mainstream smoke by drawing on the opposite or mouth end of the cigarette, which typically contains a filter. The filters are positioned to trap some components of mainstream smoke before it is delivered to the smoker.

[0003] Some smoke components, such as phenol or other phenolic compounds, may contribute to astringency and may not be effectively removed by filters.

[0004] Various options exist...
