This invention provides smoking compositions which contain a novel heteroaromatic flavorant-release additive as illustrated by the following structure:
where R is hydrogen or a C₁-C₄ alkyl group; R¹ is hydrogen or a C₁-C₈ alkyl group; and R² is a C₃-C₁₂ aromatic substituent; with the proviso that at least two R¹ groups are C₁-C₈ alkyl radicals.Under typical cigarette smoking conditions, 2-isopropylpyrazine and acetophenone are released as pyrolysis products, and enhance the flavor and aroma of the mainstream and sidestream smoke.
这项发明提供了含有一种新型杂芳香味释放添加剂的吸烟组合物,其结构如下:其中R是氢或C₁-C₄烷基;R¹是氢或C₁-C₈烷基;R²是C₃-C₁₂芳香取代基;但至少有两个R¹基团是C₁-C₈烷基基团。在典型的香烟吸烟条件下,2-异丙基吡嗪和苯乙酮作为热解产物释放出来,增强了主流烟和旁通烟的风味和香气。
