真空回潮对湖南上部烟叶香韵和杂气的影响

目的]为掌握打叶复烤过程真空回潮工序不同加工强度对郴州、衡阳、邵阳、湘西上部初烤烟叶香韵和杂气的影响,方法]在同一打叶复烤生产线对上述4种代表性湖南上部初烤烟模块进行了试验和感官质量分析。结果]结果表明：郴州上部烟焦香、甜香明显增加,花香、木香有所减弱；衡阳上部烟焦香、甜香较明显增加,木香、坚果香有所减弱；邵阳上部烟焦香、甜香较明显增加,木香、树脂香明显减弱；湘西上部烟甜香明显增加,焦香、清香略有增加,树脂香、木香有所减少。结论]4种湖南上部烟模块经过真空回潮处理,焦香或甜香均有一定幅度的提高；氮杂气和青杂气都有不同程度的降低。

Influences of Vacuum Damping Processing on Aroma and Offensive Odor of Hunan Upper Tobacco

To know the influences of vacuum damping processing on aroma and offensive odor of Chenzhou, Hengyang, Shaoyang, Xiangxi upper tobaccos, their sensory quality was evaluated after testing on the same processing line. The results indicated that: the burnt scent and sweetness scent of Chenzhou upper tobacco increased obviously, but flora scent and woody scent decreased slightly. The sweetness scent and burnt scent of Hengyang upper tobacco increased, but woody scent and nutty scent decreased slightly. The burnt scent and sweetness scent of Shaoyang upper tobacco increased obviously, but woody scent and resin scent reduced distinctly. The sweetness scent of Xiangxi upper tobacco increased obviously, the burnt scent and fresh scent increased slightly, but resin scent and woody scent decreased. After vacuum damping processing, the burnt scent or sweetness scent of four Hunan upper tobaccos increased more or less; nitrogen odor and woody odor of all the four upper tobaccos reduced to a certain extent. Results provide technical references for high efficient usage of upper tobacco.
