基于品牌需求的烤烟中部烟叶适宜单叶质量研究

为合理评价和调控烤烟单叶质量，制备豫中和滇东原料产区单叶质量梯度烟叶样品，研究了不同单叶质量烟叶的外观品质、主要化学成分、感官品质及工业可用性差异，提出基于卷烟品牌需求的烟叶适宜单叶质量。结果表明，豫中和滇东产区中部烟叶的单叶质量主要分布在14.5~26.5 g和11.0~17.0 g。豫中产区单叶质量在8.5~38.5 g，滇东产区在8.0~29.0 g范围内，随单叶质量升高烟叶身份趋厚，颜色饱和度和油分改善，烟叶还原糖、总糖和淀粉含量增加，糖碱比值上升。烟叶感官品质和工业可用性随单叶质量升高呈抛物线变化，单叶质量较低的烟叶香气品质相对较差，单叶质量较高则口感舒适性明显下降。针对"中华"品牌烟叶原料需求，豫中产区中部烟叶单叶质量在17.5~20.5 g，滇东产区在14.0~17.0 g相对适宜。

Study on the Suitable Single Leaf Mass for Middle Flue-cured Tobacco Leaves Based on Brand Demand

In order to reasonably evaluate and control the weight per leaf of flue-cured tobacco, different weight per leaf tobacco samples in central Henan and eastern Yunnan raw material production areas of Shanghai tobacco group were prepared. The differences in appearance quality, main chemical compositions, sensory quality and industrial usability of different weigh per leaf tobacco leaves were investigated and the appropriate weight per leaf based on cigarette brand demand was proposed. The results showed that the weight per leaf of middle tobacco leaves was mainly distributed during 14.5-26.5 g in central Henan and 11.0-17.0 g in eastern Yunnan production area. When the weight per leaf was in the range of 8.5-38.5 g in central Henan and 8.0-29.0 g in eastern Yunnan production areas, with the increase of weight per leaf, the tobacco leaves thickened, the color saturation and oil content improved, and the content of reducing sugar, total sugar and starch increased, the reducing sugar/nicotine enhanced. A parabolic change of sensory quality and industrial usability was showed with the increase of weight per leaf, and the aroma quality score of tobacco leaves was lower in relatively low weight per leaf tobacco leaves, while the taste comfort score obviously decreased with higher weight per leaf tobacco leaves. For the demand of "Chonghua" brand tobacco raw materials, the appropriate weight per leaf of central Henan production area was between 17.5-20.5 g, while that of eastern Yunnan producing area was 14.0-17.0 g.
