不同烘烤工艺对云烟87烟叶烘烤质量的影响

为探索江西省多雨生态条件下主栽烤烟品种云烟87的烘烤工艺操作,采用智能控制烘烤箱模拟密集烘烤条件开展了不同烘烤工艺对其烘烤质量的影响研究。结果表明,与传统烘烤工艺相比,针对多雨烟区烟叶烘烤特点的优化烘烤工艺有利于降低烟叶淀粉含量,提高总糖、还原糖含量和烟叶中质体色素的降解比例,对其他矿质元素含量等无明显影响。烟叶外观质量得到改善,烟叶等级结构、均价和上等烟叶比例有所提高。对烟叶感官评吸质量有较明显的改善作用,特别是在杂气、刺激性和余味方面。

Effects of Different Flue-curing Processes on Tobacco Quality of Yunyan 87

During recent years, bulk curing barns were widely used in China. However, a number of problems, such as shortage of roasted aroma, tight structure and light color still exist. This is because that in recent years, the construction of the bulk curing barn has rapidly developed, but the flue-curing process is still mainly the regular barn flue-curing process, which is not suitable for all the regions and for the bulk curing barn. In order to explore the curing process of Yunyan 87 under rainy conditions in Jiangxi Province, an experiment was carried out to study the effect of different curing processes on the quality of flue-cured tobacco through the use of intelligent ovens. The results showed that:Compared with the traditional curing process, the optimized curing process that was optimized based on the curing characteristics of tobacco leaves in rainy areas was conducive to reduce starch content, increase contents of total sugar and reducing sugar, and increase the proportion of degradation of plastid pigment, but had no obvious effect on contents of other mineral elements. The appearance quality of tobacco leaves was improved, and grade structure, average price and the proportion of high class leaf increased. The smoking quality of tobacco leaves was significantly improved, especially in the aspects of offensiveness, irritation and aftertaste.
