Abstract
Improved delivery of additive materials to mainstream smoke produced by smoking articles is provided through the use of a temperature sensitive powder containing an additive material, such as a flavor component, in a smoking article such as a cigarette. The temperature sensitive powder is subjected to heat which causes the temperature sensitive powder to release at least a portion of the additive material into mainstream smoke. The temperature sensitive powder encapsulates the additive materials and other portions of the smoking articles, such as sorbents or filter materials, in order to reduce additive material migration during storage.
