“兰州”卷烟湖南基地烤烟化学成分综合评价

Comprehensive Evaluation of Chemical Composition of Flue-cured Tobacco in Hunan Base of Lanzhou Cigarette Brand

为研究"兰州"卷烟湖南基地烤烟的化学成分状况,对240个样品的化学成分进行评价,并分析了2010-2017年烤烟化学成分特征.结果表明:1)湖南烤烟总糖、还原糖、总氮、烟碱、钾、氯、钾氯比和氮碱比适中,糖碱比稍低;2)品种间和等级间总糖、还原糖、烟碱、糖碱比差异有统计学意义,品种间氮碱比以及等级间总氮、钾差异有统计学意义;3)2010-2017年,除2013年和2016年总糖、2016年还原糖和糖碱比、2017年总糖和还原糖偏高外,其他年度化学成分均适中.综合分析认为,"兰州"卷烟湖南基地烤烟化学成分的质量分数整体"适中,稳定".

To study the chemical composition of flue-cured tobacco in Hunan base of lanzhou cigarette brand,the characteristics of chemical components of 240 samples were analyzed,and the annual characteristics of tobacco leaves were evaluated from 2010 to 2017.The result indicated that:1)The average concentration of total sugar,reducing sugar,total nitrogen,nicotine,potassium,chlorine,ratio of potassium to chlorine and total nitrogen to nicotine were at an appropriate level.and the ratio of total sugar to nicotine were low.2)The differences of total sugar,reducing sugar,nicotine and ratio of total sugar to nicotine were statistically significant among varieties and grades;the differences of total nitrogen to nicotine between varieties and the total nitrogen,potassium between grades were statistically significant.3)From 2010 to 2017,the total sugar were high in 2013 and 2016,the reducing sugar and ratio of total sugar to nicotine were high in 2016,the total sugar and reducing sugar were high in 2017,the chemical composition were all suitable in other years.In summary,the chemical quality in Hunan base of Lanzhou cigarette brand were moderate and stable.
