摘要
以中国主产烟区53份C3F等级中部烟叶为样品,对其焦油含量、化学成分、烟气质量之间的关系进行分析.结果表明,低、中、高焦油量烟叶的样品数分别为27、18、8个,低、中、高焦油量烟叶样品的焦油量均值分别为10.41、11.82、13.29 mg/支.对高、中、低焦油量烟叶的化学成分含量进行比较,高焦油量烟叶中还原糖含量、总糖含量较高,中焦油量烟叶中总植物碱含量、总氮含量较高,低焦油量烟叶中K含量、氯含量较高.对于烟气质量而言,随着烟叶焦油量的升高,抽吸口数、总粒相物、一氧化碳释放量和烟碱含量均呈升高趋势,而水分含量呈先降低后升高的趋势.低焦油量烟叶中总粒相物与总植物碱、总氮呈显著正相关,水分与总植物碱呈显著正相关,焦油与总氮呈显著正相关;中焦油量烟叶中一氧化碳、烟碱与K呈极显著负相关,水分与总植物碱呈极显著正相关,水分与总糖呈显著负相关;高焦油量烟叶中水分与总植物碱呈显著正相关.
Abstract
Using 53 C3F grade middle tobacco leaves from major tobacco producing areas in China as samples,the relationship among tar contents,chemical composition,and smoke quality was analyzed.The results showed that there were 27,18,and 8 samples of low,medium,and high tar tobacco,respectively.The average tar contents of low,medium,and high tar tobacco samples were 10.41,11.82,and 13.29 mg/cig,respectively.Comparing the chemical composition of high,medium,and low tar tobacco leaves,high tar to-bacco leaves had higher levels of reducing sugar and total sugar content,medium tar tobacco leaves had higher levels of total alkaloids and total nitrogen content,and low tar tobacco leaves had higher levels of K and chlorine content.For smoke quality,as the tar con-tents of tobacco leaves increased,the buff number,total particulate matter,carbon monoxide release,and nicotine content all showed an increasing trend,while the moisture content showed a trend of first decreasing and then increasing.The total particulate matter in low tar tobacco leaves was significantly positively correlated with total plant alkaloids and total nitrogen,while moisture and total plant alkaloids were significantly positively correlated.Tar and total nitrogen were significantly positively correlated;there was a highly sig-nificant negative correlation between carbon monoxide,nicotine,and K in tobacco leaves with medium tar content,a highly signifi-cant positive correlation between moisture and total plant alkaloids,and a significant negative correlation between moisture and total sugar;there was a significant positive correlation between moisture and total plant alkaloids in high tar tobacco leaves.
