云南和河南陈化的复烤片烟质量的差异

为考察气候条件对复烤片烟陈化质量的影响,研究了在云南玉溪和河南许昌两地不同气候条件下陈化云南烤烟复烤片烟的香味成分(中性、酸性和碱性)、pH值和感官质量的差异。结果表明:①云南烤烟复烤片烟在玉溪和许昌两地不同的气候环境条件下自然陈化后,样品酸碱中各类成分的变化趋势相同,但变化幅度明显不同;②醇类成分和pH值均呈降低趋势,在许昌自然陈化的降幅均大于在玉溪的降幅;③中性香味成分总量和酸碱中总量均呈增加趋势,在玉溪陈化的增幅均大于在许昌的增幅;④碱性成分也均呈增加趋势,在许昌自然陈化的增幅较大;⑤在玉溪陈化的云南烤烟复烤片烟样品的整体感官质量高于同期在许昌陈化的感官质量。

Quality Differences between Redried Strips Aged in Yunnan and Henan Provinces of China

In order to investigate the influence of climate conditions on the quality of aged redried flue_cured strips, the differences between the aroma constituents (neutral, acidic and basic constituents), pH value and smoking quality of Yunnan redried flue_cured strips aged for two years at two districts with different climate, Yuxi of Yunnan Province and Xuchang of Henan Province of China, were studied. The results showed that: 1)the neutral, acidic and basic constituents in the strips aged at the two districts changed with significantly different extents, although with the same trends; 2)the reduction of alcoholic constituents and the pH value of the tobacco aged at Xuchang were more significant than that at Yuxi; 3)the amount of neutral constituents and total amount of aroma constituents, including the neutral, acidic and basic constituents, in the tobacco aged at Xuchang were lower than that at Yuxi; 4)the increase of the basic constituents in the tobacco aged at Xuchang was higher than that at Yuxi; and 5)the smoking quality of the tobacco aged at Xuchang was not as good as that at Yuxi.
