摘要
为研究变黄时间、干筋温度对上部烟叶品质的影响,以云烟87上5片烟叶为材料,研究变黄时间(40℃稳温24、36 h)、干筋温度(64℃、68℃)对上部叶收缩率、外观质量、化学成分、感官评吸质量的影响。结果表明:不同变黄时间、干筋温度对烟叶收缩率、外观质量、内在化学成分及感官质量有显著影响。延长变黄时间,烟叶收缩率增大,同时淀粉含量降低,总糖、还原糖含量增加,内在化学成分趋于协调。干筋温度对烟叶收缩率影响较小,降低干筋温度,烤后烟叶清甜蜜甜香型风格更加突出,香气质更好,枯焦气等杂气明显减少。龙岩烟区云烟87上部叶变黄时间(40℃)延长12 h,干筋温度控制在64℃,可有效改善外观质量,化学成分更协调,感官质量有效提升,提高工业可用性。
In order to study the effects of the yellowing time and stem-drying temperature the quality of upper leaves,five upper leaves of Yunyan 87 were used as the materials to study the effects of the yellowing time(40℃for 24 h and 36 h)and stem-drying temperature(64℃and 68℃)on the shrinkage rate,appearance quality,chemical composition and sensory evaluation quality of the upper leaves.The results showed that different yellowing time and stem-drying temperature had significant effects on the shrinkage rate,appearance quality,intrinsic chemical composition and sensory quality of the tobacco leaves.When the yellowing time was prolonged,the shrinkage rate of tobacco leaves increased,the starch content decreased,the contents of total polysaccharide and reducing sugar increased,and the intrinsic chemical composition tended to be coordinated.The stem-drying temperature had little effect on the shrinkage rate of tobacco leaves,and when the temperature of stem-drying temperature was decreased,the clear and sweet flavor type of the flue-cured tobacco leaves became more prominent,the quality of aroma was better,and the impurity gases such as withered and scorched gas were significantly reduced.The yellowing time(40℃)of the upper leaves of Yunyan 87 in the tobacco area of Longyan was prolonged for 12 h,and the temperature of killing-out was controlled at 64℃,which could effectively improve the appearance quality,more harmonious chemical composition,the sensory quality and the industrial usability.
