工艺技术 烟草中糖对主流烟气成分的影响研究 魏玉磊 山东中烟工业公司技术中心 (济南 250100) 摘 要 糖是烟叶中重要组成成分，在烟草加工过程中通常被添加到烟草制品中。该文着重论述糖在烟 草制品燃烧过程中对主流烟气的影响。添加到烟草中的糖，通常可以提升烟气品质，因为糖的裂解往往 产生酸性物质，极大改善抽吸口感和烟气对喉部刺激。但进一步研究表明，糖在裂解过程中常产生醛类 物质，且该物质常与尼古丁产生协同作用，使消费者产生上瘾习惯。此外，糖在裂解过程中产生许多毒 性物质（包括一些致癌物质），特别是裂解产生的甲醛、乙醛、丙酮、丙烯醛以及2-糠醛等物质。 关键词 烟草；添加剂；糖；裂解；烟气 Sugars of Tobacco Ingredient: Effects on Mainstream Smoke Composition Wei Yu-lei Technology Center of China Tobacco Shandong Industrial Co. (Jinan 250100) Abstract Sugars are natural tobacco components, and are also frequently added into tobacco during the manufacturing process. This paper describes the fate of sugars during tobacco smoking, in particular the effect of tobacco sugars on mainstream smoke composition. The added sugars are usually reported to serve as fl avor/casing and humectants. However, sugars also promote tobacco smoking, because they generate acids that neutralize the harsh taste and throat impact of tobacco smoke. Finally, sugars generate acetaldehyde, which has addictive properties and acts synergistically with nicotine. Apart from these consumption enhancing pyrolysis products, many toxic (including carcinogenic) smoke compounds are generated from sugars. In particular, sugars increase the level of formaldehyde, acetaldehyde, acetone, acrolein, and 2-furfural in tobacco smoke. tobacco additives sugar pyrolysis smoke Keywords ； ； ； ； 2 燃烧过程中糖的反应
