“延安”（醇香） is a flue-cured tobacco product developed by the Yan'an Cigarette Factory in 1995. It employs a biological enzyme agent to harmonize the chemical components of the tobacco leaves, resulting in a rich and vibrant tobacco blend with an elegant aroma, moderate strength, and a clean, comfortable aftertaste with minimal irritation. Additionally, the filter tip incorporates a high-performance polymer adsorbent—chitosan. This non-toxic agent possesses excellent antibacterial properties and, due to its positive charge, selectively adsorbs free radicals from the smoke. Tests conducted by the Free Radical Laboratory of the Institute of Chemistry, Chinese Academy of Sciences, have shown a reduction in the relative concentration of free radicals in cigarettes containing chitosan, preserving the tobacco flavor while enhancing the smoking experience and reducing the hazards of smoking, thus safeguarding consumer interests. The cigarettes are wrapped in horizontal ribbed paper, complemented by a 28mm tipping paper.

“延安”（醇香），是延安卷烟厂于一九九五年开发的烤烟型产品。延安（醇香）使用了生物酶制剂协调烟叶的化学成分，使烟丝油润鲜明，烟香清雅，浓度适中，余味干净舒适，刺激性小。此外，烟支滤嘴中添加了具有很好吸附功能的高分子吸附剂—壳聚糖。它无毒且有很好的抑杀菌作用，它带有的阳电荷能选择性的吸附烟气中的自由基，经中国科学院化学研究所自由基实验室对添加壳聚糖的卷烟进行检测，自由基相对浓度减小，既保留了烟香，提高了吸味，又减少了吸烟的危害性，维护了消费者的利益。烟支选用横罗纹卷烟纸，配以28mm接装纸。
