散叶插签装烟持续缓慢升温烘烤工艺烘烤效果研究

摘要

为进一步提高散叶插签装烟烘烤的烟叶质量,研制了与之相匹配的持续缓慢升温烘烤工艺(T),并与生产上推广应用的烘烤工艺(CK)进行对比试验.结果表明,与CK相比,T能显著改善烟叶等级结构,极显著提高上等烟比例,下部叶、中部叶和上部叶分别提高34.57%、31.96%和15.84%;显著降低下低等烟、级外烟和光滑烟的比例,下部叶分别降低35.06%、40.66%和69.47%,中部叶分别降低32.42%、47.31%和50.48%;上部叶的下低等烟比例降低91.87%;烟叶主要化学成分含量及其派生值更适宜;香气成分含量更高,下部叶、中部叶和上部叶分别提高2.94%、6.15%和6.65%;烟叶内在质量更好.表明持续缓慢升温烘烤工艺能显著改善散叶插签烘烤的烟叶外观质量,提高烟叶内在质量和可用性.%The comparative experiment was conducted between continued slow warming technique (T) and conventional curing technique (CK) in order to further improve the quality of flue-cured tobacco leaves using the loose leaf bulk curing with leaf-holding needle. The results showed that,compared with CK,T can significantly improve commercial grades,and highly significant improve the ratio of superior tobacco leaves. Lower leaves, middle and upper leaves increased respectively 34.57%,31.96% and 15.84%. T can significantly decreased the ratio of lower grades,out of grade and slick tobacco. The lower leaves decreased respectively 35.06%,40.66% and 69.47%,the middle leaves decreased respectively 32.42%,47.31%and 50.48%. The low grade tobacco of upper leaves were decreased 91.87%. The contents of main chemical components of tobacco leaves and their derived values was moderate. The content of aroma components was higher,lower leaves,middle and upper leaves increased 2.94%,6.15% and 6.65% respectively. The intrinsic quality of tobacco leaves is better. Conclusion:the continued slow warmiug curing technology can significantly improve the appearance quality,internal quality and availability of tobacco leaves using the loose leaf bulk curing with leaf-holding needle.
