微生物对烤烟叶片烟碱含量的影响

此项研究用微生物菌株培养液喷洒烤烟采收后上、中部烟叶,烘烤结束后测定烟叶化学成分及内在品质的变化情况。结果表明,供试菌株对烟叶化学成分和评吸品质均有一定的影响。各菌株对不同部位的烟碱含量影响显著,中部烟叶1￣6号菌株处理以4号菌株效果最好,烟碱降解率达36.9%;上部烟叶1￣11号菌株处理以9号菌株效果最好,烟碱降解率达37.25%,其次依次为10号、4号菌株,烟碱降解率分别为22.80%、19.86%;就4号、9号、10号菌株处理的烤烟单体烟叶感官质量评吸结果表明,4#、9#菌株处理综合得分均高于CK,处理后香气量有所提高,香气质有改善,劲头明显下降,刺激性明显减弱,杂气明显减轻,余味好于CK。

Influence of Microorganisms on Flue-cured Tobacco Nicotine Content

The tobacco leaves were cured after spraying with each of the ten isolates and then were examined for their chemical components and the inner quality change. The results indicated that the chemical substances and the smoking quality of the treated leaves were affected in some extent and the different position leaves was affected by all the bacteria strains significantly. The middle-position leaves were treated by the isolates 1~6# isolate, the nicotine reduction rate of tobacco leaves sprayed with 4# was 36.9%, which is the highest of all tested isolates. The super-position leaves were treated by 1~11# isolates, the nicotine reduction rate with 9# was 37.25% and the next rate was the treatment of 10# and 4# isolate, 22.80% and 19.86% respectively. The leaves treated by 4#, 9#, 10# were determined their inner quality by smoking and the results showed that the total scores of 4# and 9# treatment was higher than the control. The smoking quality of treatment applied with that increased in terms of the aroma quality and volume, and the irritation strength was reduced.
