摘要:

为探究烤后烟叶不同区位化学成分与质量特性的差异性和规律性,本研究以烟叶为试验材料,从叶尖到叶基部将叶片分切为14个区位,根据片烟尺寸将烟叶划分为大片、中片、小片、碎片和碎末5个片型,对各类样品进行精准化学成分分析与聚类分析,并进行感官质量评价。结果表明:烤后烟叶不同区位、不同尺寸片烟的化学成分含量差异较大。总糖和还原糖含量从叶缘到叶主脉逐渐降低,叶尖和叶缘的烟碱、总氮含量较高,而叶基部的钾、氯及色素含量更高。根据总体化学成分,可将叶片聚类为区位1~7、9、10、大片、中片、碎片、碎末、小片,以及区位8、11~14两大类,在实际生产中聚类相近的烟叶可相互替代,以解决部分烟叶原料不足的问题。研究结果明确了烤后烟叶不同区位化学成分的分布规律,为提升烤后烟叶精细化加工水平提供了理论依据,有助于提高烟叶原料的使用价值。

Abstract:

In order to investigate the differences and distribution patterns of chemical components and quality characteristics in different leaf positions of flue-cured tobacco leaves,this study took tobacco leaves as the test material, cut the leaves into 14 different zones from the tip to the base of the leaf, and tobacco strips were classified into five categories:large strip, medium strip, small strip, broken strip and fine dust,according to the size grade. Precise chemical composition analysis,cluster analysis,sensory quality evaluation were conducted on these samples. The results showed that the chemical component contents of flue-cured tobacco leaves varied greatly among different leaf positions and the size grade of tobacco strips,with obvious variation patterns from leaf tip to leaf base. The contents of total sugar and reducing sugar gradually decreased from the leaf margin to the main vein,while the contents of nicotine and total nitrogen were higher in the leaf tip and leaf margin,and potassium,chlorine and pigment contents were more enriched in the leaf base. Based on the overall chemical components,the leaves can be clustered into two major categories:zones 1-7,9,10,and large strip,medium strip,broken strip,fine dust,and small strip,as well as zones 8 and 11-14. In practical production,tobacco leaves with similar clustering results can be substituted for one another,thereby alleviating the shortage of certain tobacco raw materials. The results of the study clarified the distribution patterns of chemical components in different positions of flue-cured tobacco leaves,and provided a theoretical basis for improving the refined processing of flue-cured tobacco and enhancing the utilization value of tobacco raw materials.

Key words: flue-cured tobacco leaf, different positions, chemical components, quality characteristics, differential analysis
