湿度对白肋烟晾制的影响

Effect of Humidity on Air-curing of Burley Tobacco

摘要: 2001~2003年在湖北省恩施市进行了不同湿度下的白肋烟晾制试验。从等级比值、外观质量、内在品质等方面综合比较,晾制各阶段晾房内适宜的相对湿度范围分别为:凋萎期76.8%~81.1%、变黄期72.5%~81.6%、变褐期71.4%~73.5%、干筋期41.7%~61.7%。在此湿度下白肋烟晾制期为5~6周;调制的烟叶等级率较高,上、中等烟比例平均分别为42%和45%。上部和中部叶综合评吸得分分别为80.03和86.55,达到中等和中偏好档次,烟叶香气质、香气量、刺激性、燃烧性均优于高湿和低湿处理。烟叶颜色较深,呈近红黄至红黄,光泽好,组织疏松,叶面皱缩,颗粒状物质多,质地柔软。

Abstract: The air-curing experiments of burley tobacco at different humidity were conducted in Enshi City of Hubei Province during 2001-2003.The tested tobacco was evaluated comprehensively in terms of grade, apparent and smoking quality.The suitable ranges of relative humidity in curing barn in the stages of wilting, yellowing, browning and vein drying were 76.8%-81.1%, 72.5%-81.6%, 71.4%-73.5% and 41.7%-61.7%, respectively.The curing period was 5-6 weeks, the average proportions of high and middle grades of cured leaves were 42% and 45%, respectively;and the sensory test results showed that the aroma, flavor, irritation and combustibility of leaves were better than that of the leaves cured beyond the said humidity ranges.
