Tobacco treatment process

摘要

Flavorful tobacco extracts are provided by subjecting a tobacco extract to heat treatment. The tobacco extract is contacted with an ammonia compound capable of releasing ammonia or a base capable of releasing ammonia indigenous to the tobacco extract, and then is subjected to a heat treatment above about 100 DEG C. in a pressure controlled environment. Resulting flavorful extracts are useful as forms of tobacco in cigarettes and other smoking articles.
