Abstract:

In order to explore the quality characteristics of flue-cured tobacco hybrid ‘YY021’, a multi-point field comparative test was conducted with ‘Heluo No.1’ as the control variety. The appearance quality and sensory quality of raw tobacco were evaluated, and the contents of chemical components and aroma components were determined to comprehensively evaluate the quality and aroma components of tobacco leaves. The results showed that the quality of ‘YY021’ middle tobacco was slightly better than that of upper tobacco. The scores of chemical composition, sensory quality evaluation and comprehensive evaluation of ‘YY021’ were significantly higher than those of ‘Heluo No.1’, and the performance of each pilot was consistent. The contents of five kinds of neutral aroma components in the upper leaves of ‘YY021’ were higher than those in the middle leaves. The content of sugar and browning products of middle leaves of ‘Heluo No.1’ were significantly higher than those of ‘YY021’. The contents of total neutral aroma components, chlorophyll degradation products (neophytadiene) and cembranoids (solanone) in middle leaves of ‘YY021’ were significantly higher than those of ‘Heluo No.1’, which were 278.93, 243.80 and 38.21 μg/g, respectively. The quality of ‘YY021’ was better than that of ‘Heluo No.1’. Neophytadiene, ketone, benzyl alcohol, β-damone and giant bean trienone were important aroma components that affect their quality.

Key words: flue-cured tobacco, ‘YY021’, quality, aroma components, sensory quality, chemical composition, appearance quality
