四种不同香型乌龙茶在卷烟滤嘴中的应用研究

Performance of Four Oolong Teas with Different Flavor Style in Cigarette Filter

以铁观音清香型茶、铁观音浓香型茶、黄金桂清香型茶、黄金桂浓香型茶4种具有代表性的不同香型安溪乌龙茶为研究对象,采用CO2超临界萃取法将其进行提取,得到提取物。以固相微萃取-顶空进样,GC-MS法对不同香型安溪乌龙茶提取物进行分析,比较各香型提取物的挥发性成分和致香成分的差异。同时将其应用于卷烟丝束当中,评价卷烟抽吸品质,探讨其在卷烟滤棒中应用时的增香效果。结果表明,黄金桂清香型茶超临界萃取物中致香成分最为丰富,特征成分含量较高,同时与卷烟烟气的谐调性较好,能显著改善卷烟的抽吸品质,具有较好的开发应用前景。

To get a better understanding of the performance of oolong tea with different flavor style when used in cigarette filter,four kinds of oolong tea from Anxi town,named fresh-flavor Tieguanyin,rich-flavor Tieguanyin,fresh-flavor Huangjingui and rich-flavor Huangjingui,respectively,were selected and extracted by CO2 Supercritical extraction method,from which the extracts were analyzed by head-space SPME-GC/MS method.The results indicated that the extract from fresh-flavor Huangjingui represented relatively rich and high content volatile components,especially aroma components.When added to diacetate cellulose tow filter,it showed a more significantly active impact on cigarette quality taste in terms of aroma richness,irritation and comfortableness.
