ABSTRACT
I
nvestigations were made on the effect of type and amount of silicate materials directly added to tobacco cigarette mixtures on the major physical properties of cigarettes. Four types of silicate materials (type-Y zeolite, ultra stable type-Y zeolite, pentasile-type zeolite and amorphic silicon -carbon dioxide) were added directly to tobacco mixtures in amounts of 3% and 5% of the total mass of tobacco mixture. Cigarettes were made industrially, on cigarette making machine. Zeolites were synthesized and their physical-chemical characteristics were assessed at the Faculty of Physical Chemistry in Belgrade. Physical characteristics of cigarettes were made on SODIMAT and statistic analysis of the results was performed on the same device. Based on investigations it was concluded that direct addition of silicate materials in cigarette mixture has no effect on mass and diameter of the investigated cigarettes. In contrast to that, it was determined that resistance to draw is significantly affected by the type and quantity of silicate material added in the mixture. All four types of silicate materials cause changes of the resistance to draw. The level of change is proportional to the amount of applied silicate material.
