摘　　要：以云烟87上部烟叶为研究对象,以颜色深浅度、色度、均匀度、油分、常规化学成分和感官质量为评价指标,开展了不同润叶和复烤强度对上部烟叶质量的影响研究。结果表明,随着润叶强度的增加,润叶后烟叶颜色逐渐加深,色度偏向深橘黄,均匀度逐渐变差,油分增加;复烤后烟叶颜色变浅,色度向柠檬黄转变,均匀度提升,油分降低,较高温度复烤的烟叶均匀度和油分优于低温复烤;随润叶强度增加烟叶烟碱和总糖含量逐渐升高,复烤后其含量逐渐下降;随润叶强度增加润叶后的感官质量逐渐降低,低水分润叶下随复烤温度增加感官质量提升,高水分润叶下随复烤温度增加感官质量下降。综合来看,低水分润叶(W15%)和较高温度复烤(T 70℃)更有利于上部烟叶质量的形成。Took the upper tobacco leaves of Yunyan 87 as the research object,the effects of different moistening and re-drying intensities on the quality of upper tobacco leaves were studied with the evaluation indexes of color depth,chroma,uniformity,oil content,conventional chemical composition and sensory quality.The results showed that with the increase of leaf moistening intensity,the color of tobacco leaves gradually deepened,the chroma tended to be dark orange,the uniformity gradually deteriorated,and the oil content increased after leaf moistening.After re-drying,the color became lighter,the chroma changed to lemon yellow,the uniformity increased,and the oil content decreased.The uniformity and oil content of higher temperature re-drying were better than those of low temperature re-drying.The contents of nicotine and total sugar increased gradually with the increase of leaf moistening strength,and decreased gradually after re-drying.With the increase of leaf moistening strength,the sensory quality after leaf moistening gradually decreased.Under low moisture leaf moistening,the sensory quality increased with the increase of re-drying temperature,and the sensory quality decreased with the increase of re-drying temperature under high-moisture leaf moistening.On the whole,low-moisture moistening leaves(W15%) and higher temperature re-drying(T 70 °C) were more conducive to the quality of upper tobacco leaves.
