降低挥发性羰基化合物材料在卷烟滤嘴中的应用研究

摘要

Effects of different technological parameters on harmful compounds reducing performance and sensory quality of cigarette were investigated. Such features as additive amount of functional material, pressure drop of multiple filter, and length of feeding section were studied in order to optimize application of functional material for reducing volatile carbonyl compounds in multiple filter. Results showed that the optimum technological conditions for selectively reducing volatile carbonyl compounds in cigarette smoke were as follows: 1) additive amount of functional material was 30mg/cig; 2) multiple filter was combined with 10 mm feeding section and 15 mm blank section; and 3) pressure drop of blank section, feeding section and multiple filter were 2800Pa/120mm, 4000Pa/120mm, and 2740Pa/100mm, respectively. When such conditions were applied total volatile carbonyl compounds in cigarette smoke were reduced up to 32.3%, and no significant difference in sensory quality was detected between optimized cigarette and blank cigarette.%为优化降低烟气中挥发性羰基化合物的功能材料（即降羰基物材料）在卷烟复合滤嘴中的应用工艺条件，从功能材料添加量、滤嘴压降搭配、加料段长度等方面研究不同工艺条件对降羰基物材料的减害性能及其对卷烟感官质量的影响。结果表明，当降羰基物材料在卷烟中的添加量为30 mg/支，同时二元复合滤嘴为10 mm加料段+15 mm白段，其中加料段压降为4000 Pa/120 mm，白段压降为2800 Pa/120 mm，复合棒压降为2740 Pa/100 mm时，卷烟主流烟气中挥发性羰基物释放总量的选择性降低率达到32.3%，且卷烟感官质量与对照卷烟相比无显著差异。
