目的：目前卷烟中梗丝的颜色普遍太浅，和叶丝搀兑在一起就会出现颜色不协调。同时梗丝燃烧所带来的木质气、生青气、干燥感、灼烧感等不良感受，进一步限制了梗丝的使用范围，为此需要改善梗丝颜色和感官质量。方法：我们借鉴雪茄烟传统加工工艺，通过试验找到了能较好解决上述问题的方法：烟梗首先用水漂洗，晾置后放入蒸房进行熏蒸，再按照正常梗丝加工工艺制梗丝。结果：通过这种方法得到的梗丝烟丝呈现橘红、红棕色，与烟丝颜色更为接近，木质气、生青气大幅降低，干燥感、灼烧感略微降低，外观质量和感官质量改善明显。结论：借鉴雪茄烟传统的“蒸晾漂洗”工艺对烟梗进行预处理，可以有效加深梗丝颜色和改善梗丝感官质量。
Purpose: At present, the color of tobacco cut stem is generally too light in cigarette, and the color will be inconsistent when mixed with tobacco leaf. At the same time, wood gas, immature gas, dry feeling, burning feeling and other adverse feelings caused by stem burning further limit the use of tobacco stem, so it is necessary to improve the cut stem color and sensory quality. Methods: We used the traditional processing technology of cigar for reference, and found a better way to solve the above problems through experiments: firstly, rinse the tobacco stem with water, put it in the steam room after airing, and then steam it, and then the cut stem is made according to the normal stem processing technology. Results: The cut stem color obtained by this method was orange red and reddish brown, which was more similar to the color of tobacco. The wood gas and immature gas were greatly reduced, the sense of drying and burning was slightly reduced, and the appearance quality and sensory quality were improved to a certain extent. Conclusions: It can effectively deepen the color and improve the sensory quality of the tobacco cut stem.
