The Global Tobacco market comprises three major categories of products: cigarettes, cigar and cigarillos, and other tobacco products. In 2013, cigarettes dominated the Global Tobacco market with a share of more than 85 percent. The rising prevalence of smoking worldwide coupled with increasing disposable income and active participation of the female population in smoking is fueling the growth of the Global Tobacco market. In terms of geography, China led the Global Tobacco market in 2013. However, an increase in the demand for e-cigarettes acts as a major threat to the traditional Cigarette market worldwide.

Nicotine gum is a smoking cessation product that helps smokers to slowly get off nicotine. Nicotine released from chewing nicotine gum is absorbed into the blood stream through the linings of the mouth. Nicotine gums help the human body battle the strong urges for nicotine after cutting down on cigarettes. They are available in various dosages and can be consumed according to the level of addiction.

为提高加香胶囊滤棒的生产效率,采用伺服控制和数据信号处理技术研制了滤棒加香胶囊添加装置。该装置由控制单元、供给料斗、执行机构、负压风机等部分组成,通过控制单元采集机组生产速度信号,由伺服电机带动执行机构的主辊和副辊旋转,以满足胶囊在滤棒中的间距分布要求,同时对胶囊缺失及胶囊间距不合格滤棒进行剔除。结果表明:该装置运行稳定,操作方便,生产的加香胶囊复合滤棒的圆周、吸阻、硬度、圆度等指标均达到工艺要求。滤棒中的胶囊排列均匀,间距稳定,加香胶囊滤棒和加香胶囊复合滤棒中胶囊缺失支数均为零,胶囊间距不合格支数分别为4支/万支和1支/万支。实现了加香胶囊复合滤棒的批量生产,且不会影响普通滤棒的正常生产。

运用模糊数学和主成分分析方法计算出代表烟叶质量状况的化学成分可用性指数(CCUI值),对曲靖烟叶化学成分可用性进行综合评价,分析了化学成分对感官评吸质量的影响。结果表明:1曲靖烟叶烟碱、钾、氯含量和氮碱比适中,总糖、还原糖含量和钾氯比、糖碱比偏高,总氮和淀粉含量稍低。2曲靖烟叶氯含量在等级间差异不显著,总氮含量在品种间差异不显著,氮碱比在品种间和产地间差异不显著,其余化学成分在等级、品种和产地间均存在显著或极显著差异;烟叶化学成分可用性等级间表现为:C3F>B2F>X2F,品种间为:K326>红大>中烟100>云烟85>云烟97>云烟87>NC102>NC297,产地间为:师宗县>罗平县>麒麟区>陆良县>宣威市>沾益县>会泽县>马龙县。3灰色关联分析表明,曲靖烟叶化学成分主要影响感官评吸质量评价指标中的灰色、燃烧性、劲头和香气质。

为了筛选出有利于提高晒烟品质的调制方式,以四川省达州市万源县主栽品种"万毛3号"为材料,研究了晾晒结合调制方式对万源晒烟调制过程中含水率、色素降解速率及烟叶品质的影响。结果表明,不同调制方式的烟叶含水率和色素含量变化有显著差异,随着晒制前晾制时间的增加,烟叶失水速率和色素降解速率均逐步减慢。烟叶失水速率的减缓有利于类胡萝卜素的充分降解。调制方式对调制后烟叶感官品质有一定的影响,适当延长晾制时间有利于烟叶外观和感官品质的提高。综合分析,晾制10 d后晒制的调制方式有利于色素的充分降解及外观和感官品质的提高,调制后烟叶化学成分协调,品质较好。
