Description

A filter containing a solid dispersion containing a water-soluble flavor and a smoking article containing the same

The present invention relates to a filter containing a solid dispersion containing a water-soluble spice, a smoking article including the same, and a method for preparing the solid water-soluble spice dispersion.

A combustible smoking article such as a cigarette has a tobacco column surrounded by cigarette paper and a filter column including a filter surrounded by tip paper and filter wrappers. Cigarettes are used by a smoker lighting the distal end of the cigarette and burning the cut sheath. The smoker then receives the mainstream smoke by drawing into the proximal end, which typically contains a filter. The filter is arranged to capture some components of the mainstream smoke before it is delivered to the smoker.

As such, the filter captures some components of mainstream smoke, has an effect of improving flavor generated from smoke components, and may include a flavoring agent to increase the effect. Accordingly, to release the flavoring agent, a capsule containing the flavoring agent may be placed in a filter. The capsule is prepared using agar, and medium-chain fatty acid triglyceride (MCTG) is mainly used as a solvent for the flavoring contained in the solution in the capsule. However, the manufacturing process of the capsule using the agar is complicated to use a water-soluble fragrance, and since the MCTG solvent is fat-soluble, the use of the fragrance is limited to only the fat-soluble fragrance.
