自透接装纸对降焦减害及感官质量的影响

Impact of naturally-porous tipping paper on delivery of harmful substances and sensory quality

滤嘴通风技术是目前国际上应用较为普遍的降焦手段之一,因其技术较为简便,且降焦效果明显而被广泛使用。目前主要是通过使用激光打孔接装纸,辅以高透成形纸的通风滤嘴实现。用自然透气度的接装纸代替打孔接装纸,可以免去打孔工序。将不同透气度的自透接装纸卷制成香烟样品,分析样品的主流烟气中有害物质的释放量、通风率、通风率变异系数,并对卷烟感官进行了评吸。在同等条件下与激光打孔烟用接装纸对进行对比,结果表明:在相同透气度的情况下,自透接装纸样品的一些有害成分如烟碱、焦油、巴豆醛、CO等的释放量更低,通风率变异系数均值为5.84%,低于打孔接装纸样品(6.67%)。当透气度低于160CU时,自透接装纸样品烟香更丰满、细腻、谐调,余味更纯净舒适。

Filter ventilation technology is one of the widespread strategies to reduce the delivery of tar and other harmful substances. Due to its easily-opera bility and pronounced advantages, this technology is widely used in cigarette production. At present, it can be achieved by using the filter with perforated tipping paper. A naturally-porous tipping paper was used instead of perforated tipping papers in cigarette production. Tipping paperswith different porosities were evaluated as regards the delivery of harmful components in the mainstream smoke, the ventilation rate, the variation coefficient of ventilation, and the sensory quality. It was found that, for naturally-porous tipping paper, the delivery of nicotine, tar, crotonaldehyde, carbon monoxide, etc., was much less than perforated tipping paper at the same porosity. The average value of ventilated variation coefficient was 5.84%, which is lower in comparison with the perforated tipping paper（6.67%）. In the case of the porosity of less than 160 CU, the cigarette aroma was more plentiful and elegant, and the aftertaste was more comfortable.
