摘要
【目的】探明打叶复烤生产过程中增温增湿工序处理烟叶常规化学成分的变化规律,为打叶复烤均质化评价指标的选择提供参考。【方法】采用基于打叶复烤规模化生产的半叶对照法,研究打叶复烤生产过程中真空回潮、润叶和烟片复烤3个增温增湿工序对复烤前后及原烟与复烤烟片烟叶化学成分的影响,筛选烟叶加工过程和成品烟片稳定性的评价指标。【结果】真空回潮、润叶和烟片复烤3个工序对烟叶化学成分均有不同程度的影响。真空回潮加工后,烟叶的烟碱、总糖、还原糖、总糖/烟碱、总氮、pH和淀粉的含量分别降低0.05%、0.16%、1.46%、0.43、0.03%、0.07和0.41%。其中,总糖/烟碱、总氮和淀粉的含量在加工前后差异显著,还原糖含量和pH差异极显著,烟碱和总糖含量在加工前后呈降低趋势但无显著差异。经润叶和烟片复烤工序加工后,烟叶的还原糖含量分别降低0.34%和0.59%,加工前后还原糖含量的差异显著或极显著。复烤烟片各成分含量均较原烟下降,其中,总糖、还原糖、总氮及淀粉含量分别下降0.44%、0.87%、0.10%和0.48%,差异极显著;总糖/烟碱和pH分别下降0.39和0.06,差异显著;烟碱含量下降0.06%,差异不显著。【结论】打叶复烤生产过程中真空回潮、润叶和烟片复烤关键工序对烟叶化学成分具有调控效应,烟碱可作为加工过程及成品烟片的均匀性评价指标。
【Objective】The change rules in conventional chemical components of tobacco leaves under heating and humidifying treatment during the threshing and redrying process were explored to provide a reference for the selection of homogenization evaluation indicators for threshing and redrying.【Method】A half leaf control method based on large-scale production of leaf threshing and redrying was adopted to study the effects of three heating and humidifying process,namely vacuum condition,moisturizing,and tobacco redrying,on the chemical composition of tobacco leaves before and after redrying,as well as the raw and redried tobacco,then the evaluation indicators during the process of tobacco leaves and the stability of finished tobacco were screened.【Result】The three process of vacuum condition,moisturizing,and tobacco redrying had different influences on the chemical composition of tobacco leaves.The contents of nicotine,total sugar,reducing sugar,total sugar/nicotine,total nitrogen,pH and starch in tobacco leaves after vacuum condition decreased by 0.05%,0.16%,1.46%,0.43,0.03%,0.07 and 0.41%,respectively.Among them,the contents of total sugar/nicotine,total nitrogen,and starch showed significant differences before and after processing,while the content of reducing sugar and pH showed extremely significant differences,while the contents of nicotine and total sugar had a decreasing trend before and after processing,but there was no significant difference.After moisturizing and redrying of tobacco leaves,the reducing sugar content of tobacco leaves decreased by 0.34%and 0.59%,respectively,and there were significant or extremely significant differences in reducing sugar content before and after processing.Comparing with the raw tobacco,the component content of redried tobacco decreased,among which the total sugar,reducing sugar,total nitrogen and starch content decreased by 0.44%,0.87%,0.10%and 0.48%respectively,with an extremely significant difference;The total sugar/nicotine and pH decreased by 0.39 and 0.06,with a significant difference;The nicotine content decreased by 0.06%without a significant difference.【Conclusion】The key process of vacuum condition,moisturizing and redrying has a regulation effect on the chemical composition of tobacco leaves during the threshing and redrying process,and nicotine can be used as an index to evaluate the uniformity of the processing process and the finished tobacco.
