烟丝添加剂对卷烟燃烧温度和烟气成分的影响研究 总被引:1,自引:0,他引:1
利用自行开发的微小测温热电偶装置,对添加各种钾盐的卷烟的最高燃烧温度进行了测量,并对相应的卷烟的烟气成分进行了检测。研究发现,多种烟丝添加剂的加入都可以降低卷烟的最高燃烧温度,其中乙酸钾的效果最好,而且可以大幅度减少烟气中氰化氢、氨、苯酚、巴豆醛、NNK和一氧化碳等六种成分的释放量。另外,利用TG-DTA方法对添加钾盐的烟丝在空气气氛中的燃烧和氮气气氛中的裂解进行了研究,分析了钾盐对烟丝燃烧状态的作用机理。同时,重点讨论了钾盐的添加对降低卷烟主流烟气中CO释放量的影响机制。 相似文献

采用饱和水溶液法制备荆芥挥发油-β-CD包合物,并用紫外可见分光光度法、X-射线衍射对包合物进行表征。研究了β-CD和荆芥挥发油-β-CD包合物吸附溶液中苯酚的性能。此外,还将β-CD以及荆芥挥发油-β-CD包合物作为添加剂添加到卷烟滤嘴中,研究其对卷烟主流烟气中苯酚的影响。结果表明,β-CD和荆芥挥发油-β-CD包合物吸附溶液中苯酚的动力学模型都是准二级动力学模型。当添加剂用量为30mg时,β-CD以及荆芥挥发油-β-CD包合物对卷烟主流烟气中苯酚的降低率分别为74.01%和88.9%。此外,添加剂还可以有效降低卷烟主流烟气中总粒相物的含量。 相似文献

为了解介孔材料在卷烟中应用的安全性,论文以介孔氧化铝为研究对象,将其添加到卷烟滤嘴中,按照CORESTA(国际烟草科学研究合作中心)标准方法,通过中性红细胞毒性试验、细菌回复突变试验(Ames试验)以及体外微核试验,对介孔氧化铝的卷烟应用安全性进行了毒理学评价。同时,通过卷烟感官质量评吸评估了介孔氧化铝对卷烟吸味的影响。结果表明,在卷烟滤棒中添加介孔氧化铝后,与对照卷烟相比,不会增加主流烟气总粒相物的遗传毒性,细胞毒性会略有降低,说明介孔氧化铝在卷烟中应用是安全的。卷烟感官质量评价证明介孔氧化铝对卷烟吸味无负面影响,还可以降低烟气刺激性。 相似文献

Two-stage dehydration method of flue-cured tobacco in rotary dryer was experimentally evaluated and compared to the single-stage dehydration process. The characteristic flavor components in dried cut tobacco, including major Maillard reaction compounds and carotenoid degradation products, as well as drying rate were analyzed for different two-stage dehydration operations. The results showed that both the pre-drying temperature and intermediate moisture content had a significant effect on the overall drying rate of cut tobacco during two-stage drying. On the other hand, the retention of characteristic flavor components in tobacco, especially Maillard reaction compounds retention, was influenced significantly by the final drying temperature as well as intermediate moisture content. The 10°C increase in the final drying temperature from 100 to 110°C reduced the retentions of Maillard reaction compounds and carotenoid degradation products by 14.5 and 9.4%, respectively. Change of intermediate moisture contents from 19 to 15% reduced the Maillard reaction compounds retention by 14.7%. Given the consideration of characteristic flavor components’ retention and drying process efficiency, two-stage dehydration of cut tobacco in rotary dryer could reach a better performance as compared with the single-stage dehydration. The cylinder-wall temperature combination of 140/100°C with the 17% intermediate moisture content could be used as the optimal two-stage condition for the investigated flue-cured tobacco. 相似文献

Smoking food tobacco material include flue-cured tobacco leaves, expanded stems, and reconstituted tobacco sheets. As the main raw material in the cigarette industry, the quality of flue-cured tobacco leaves is very important to the smoking food products. The effects of different combined moistening and redrying treatments on the physicochemical and sensory changes of flue-cured tobacco leaves have been systemically studied. This work has demonstrated that the steam moistening and low-temperature slow redrying (SM–LTSR) processes can improve the moisture content and color uniformity of tobacco leaves (p?0.05). More importantly, the degradation of colorant and polyphenol precursors in tobacco leaves can be reduced for different redried lamina, and the average degradation amounts can be decreased by 30.63 and 22.41%, respectively. The total amount of volatile compounds can be decreased by 9.61% in comparison with the steam-water mixing moistening and high-temperature redrying (SWM–HTR) processes. We conclude that the mid-high-grade tobacco leaves should be processed through the SM–LTSR treatments to improve the color brightness, quality stability and retain flavor, while the low-grade tobacco leaves should be processed through the SWM–HTR processes to improve the processability, aftertaste and remove the offensive odor in actual threshing and redrying. This work has formed the suitable processing methods for different qualities of tobacco leaves and has laid the theoretical foundation for the quality improvement and flavor preservation of tobacco leaves. 相似文献
