摘要:为了弱化卷烟纸木质气，分析了5种牌号浆板的理化指标，筛选出3种低木质素浆板，测定其在不同打浆时间、不同漆酶用量下的打浆性能，并研究打浆工段漆酶处理浆板对卷烟纸物理指标及细支卷烟样品主流烟气成分、感官特性的影响。结果表明，北木牌木浆板、鹦鹉牌木浆板、法国大麻浆板3种浆板卡伯值较低，木质素含量低，且以它们为原料制成的细支卷烟木质气较弱。随着打浆时间、漆酶用量增加，3种低木质素浆板打浆度提升，卡伯值下降，打浆时间为120 min时，3种浆板打浆度达到最高，卡伯值达到最低且漆酶用量为2 kg/t纸最合适。在打浆工段加入漆酶后，卷烟纸抗张强度、伸长率、抗张能量吸收分别提高9.78%、3.12%、2.33%，卷烟纸性能明显得到改善；将卷烟纸样品在细支卷烟紫气东来（汾清香）上进行实验，在烟丝与卷烟辅料相同的条件下，细支卷烟样品烟气CO释放量下降16.63%；细支卷烟样品香气增加，刺激性减小，木质气减弱，感官质量提高。

Abstract:In order to weaken the woodiness of cigarette paper， the physicochemical indices data of five grades of pulp boards were analyzed， and three kinds of low-lignin pulp boards were screened out. Effects of enzyme-treated pulp sheet on physical parameters of cigarette paper， mainstream smoke composition and sensory characteristics of slim cigarette samples. The results showed that the three pulp boards of Beimu brand wood pulp board， Parrot brand wood pulp board and French hemp pulp board had low Kappa value and low lignin content， and the woodiness of thin cigarette samples which were made from them was weak. With the increase of beating time and the dosage of laccase， the beating degrees of the three low-lignin pulp boards were increased， and the Kappa values were decreased. When the beating time was 120 min， the beating degrees of the three types of pulp boards reached the highest， and the Kappa value reached the lowest and the consumption of 2 kg of laccase per ton of paper was the optimum dosage. After adding laccase in the beating section， the tensile strength， elongation， and tensile energy absorption of cigarette paper were increased by 9.78%， 3.12%， and 2.33%， respectively， and the performance of cigarette paper was obviously improved. The cigarette paper samples were tested on the fine cigarette purple gas donglai （Fen Qingxiang）， in the tobacco and cigarette accessories under the same condition， the release amount decreased by 16.63%， the aroma of thin cigarette samples increased， the irritation and woodiness decreased， and the sensory quality was improved.
