【摘要】 本文对卷烟感官舒适性的相关因素进行系统研究,分析引起干燥感明显、刺激性偏大和口腔痰多等吸食舒适度下降的关键因素,研究提高卷烟吸食舒适度的系统解决方案,提升中式卷烟内在品质,提高卷烟保润性能的核心技术,为解决卷烟工业企业所面临的共性问题提供理论依据和技术支撑,增强中式卷烟核心竞争力。以国内外60个代表性烟叶原料为研究载体,具体研究内容包括以下几个方面：1.建立了卷烟感官舒适性评价方法,并对60个国内外代表性烟叶原料进行了感官舒适性评价；2.建立了检测游离烟碱超高效液相色谱分析方法。该法的相对标准偏差为0.15%,回收率在96.6%～103.7%之间,回归方程为：Area=9627.2×C+475.79,相关系数r=0.9999,烟碱浓度在0.06465-129.3μg/ml范围内线性关系良好；3.利用仪器分析方法,检测了60个单料烟样品主流烟气中氨、烟碱、游离烟碱、主要羰基化合物、主要酚类化合物的含量,分析了不同烟叶中氨、烟碱、游离烟碱、主要羰基化合物、主要酚类化合物的含量分别规律。结合60个单料烟样品的烟气化学数据及感官评价数据,利用相关性分析方法,深入分析了主流烟气中氨、烟碱、游离烟碱、主要羰基化合物、主要酚类化合物的含量对卷烟感官舒适性的影响规律；4.以“云烟(紫)”叶组为载体,考察了甘油、丙二醇、山梨醇、蜂蜜、转化糖、葡萄糖、木糖醇等常用添加剂对卷烟舒适性的影响,总结了各添加剂的适宜用量。各种保润剂均有其适宜的添加量,保润剂的过量添加会对卷烟感官舒适性带来负面影响,在卷烟的开发与维护过程中,应该根据保润剂对烟丝的保润功效以及对卷烟感官舒适性的影响情况来选择合适保润剂类型及其用量,以达到最佳的使用效果；5.研究了不同类型保润剂的保润机制,根据保润剂的不同保润机制开发了具有烟丝保润、防潮功效的多糖类、两性物质类新型保润剂,这些保润剂与烟草具有较好的配伍性。更多还原

【Abstract】 In this work, a comprehensive investigation into Correlation factor analyses of sensory coziness of cigarettes had been conducted, based on some key factors including dryness, irritation and cleanness of sensory quality of cigarettes. It aims to improve the Chinese type cigarette quality to achieve a higher level of sensory coziness, consequently promote the competitive power in the market.60 representative tobacco raw materials which plants in china and other countries were used as research materials. The study includes the following five aspects: 1.Established cigarette sensory coziness evaluation methods, and 60 representative raw materials of tobacco were evaluated by using this methods.2. A ultra high performance liquid chromatographic method (UPLC) was developed for determination of total nicotine and free-base nicotine in cigarette MainStream Smoke, The extraction conditions of free nicotine and protonated nicotine in trapped mainstream cigarette smoke total particulate matter were studied by using water and chloroform. Mobile phase was consisted of trifluoroacetic acid buffer (pH=3) and acetonitrile (86:14(v/v)) containing 0.004 M sodium heptanesulfonate as an ion pair agent. The linearity was obtained in the range of 0.06-129μg/ml concentrations of nicotine. The regressive equation is Area= 9627.2×C+475.79. The correlation coefficient was 0.9999. The recoveries of nicotine were ranged from 96.6-103.7% with average value of 99.6%. The limit of detection was 60ng/ml. The method was applied to the actual commercial cigarettes.3.60 samples of mainstream smoke chemical compounds including ammonia, nicotine, free based nicotine, main carbonyl compounds, main phenolic compounds were measured by using relevant analytical instrumental methods and the content distribution of these compounds was analyzed. The results of mainstream smoke chemical compounds from 60 single-grade cigarette samples and sensory evaluation data were used to analyse the correlation between contents of these compounds and cigarette sensory coziness by statistical analysis in detail.4. The influences of sensory coziness of cigarette caused by humectant, such as glycerin, propylene glycol, Sorbitol, honey, glucose, Xylitol were investigated. Subsequently a proper amount of humectan in cigarette was discussed. An excess content of humectant in cigarette can cause a negative effection to sensory coziness of smoking.5. New humectants of polysaccharides and surfactants had been developed based on the preceding results. They have some better performance and compatibilities for use in cigarette. There are no harmful chemicals found in our study.更多还原
