摘要:
将34种单等级烟叶通过二氧化碳膨胀制成膨胀烟丝,测量膨胀前后烟丝的整丝率、碎丝率和填充值,研究膨胀前后烟丝各物理结构指标的变化规律,并比较等级、部位等因素对于膨胀烟丝物理结构的影响。结果表明,烟丝膨胀后,整丝率显著性下降,填充值显著性上升,碎丝率变化不显著。不同等次和部位的烟丝膨胀前后结构指标变化存在一定差异, 下等烟、下部烟和上部烟的整丝率显著下降,碎丝率增加较多,而中部烟和中上等烟整丝率保持较好,碎丝增加较少。

Abstract:
Thirty-four tobacco leaf samples were expanded by means of dry-ice expansion. Some physical structure indices, such as proportion of long strands, proportion of broken strands, and filling power of cut tobacco, were tested and compared before and after the expansion. Subsequently, the influence of the expansion on physical structure of various stacks and grades was also compared. The results indicated that after expansion the proportion of long strands significantly decreased, while the filling power significantly increased, and the proportion of broken strands had no significant change. The change of physical structure indices of various cut tobacco showed a little difference. The proportion of long strands in low-grade tobacco, lower tobacco, and upper tobacco significantly declined, while the proportion of broken strands greatly increased. However, the proportion of long strands in middle-stack, middle-grade, and upper-grade tobacco remained stable, whereas the proportion of broken strands slightly increased.
Key words:  expanded cut tobacco  proportion of long strands  filling power
