Great importance was attached to smoking safety in design and technology of the blend. Combustion accelerating agents were applied to upgrade the burning degree, raise the burning temperature and accelerate the speed of combustion. Catalyst was used...

Free radicals in smoke are believed to be major contributors to the initiation and promotion of various forms of cancer, presumably by increasing the oxidative stress in lungs. We will describe a new filter based on natural polyphenols which scavenge...

R. J. Reynolds Tobacco Company recently developed a process for flue-curing tobacco that results in substantially lower concentrations of tobacco-specific nitrosamines. The technology is based on the use of heat exchangers instead of direct-fired...

It has been suggested that as 'tar' and nicotine deliveries from cigarettes have been reduced by the Tobacco Industry, in line with regulations and agreements with national governments, smokers have inhaled deeper to achieve more efficient uptake of...

Around the world, international machine smoking norms (e.g. ISO and FTC) are used to determine tar and nicotine yields of cigarettes, with the main purpose of comparing smoke yields from the cigarettes. There has recently been an expectation by some...

The "free" or "extractable" nicotine delivery is used as an index to the smoke impact of cigarettes. The term "free" nicotine is used in regard to that form of nicotine, which may be steam-distilled or extracted by organic solvents, without...

The cigarette industry is currently being asked by various regulatory bodies to provide significant quantities of data on tobacco products. Included within some of these requests is a requirement for providing mainstream smoke yield data under a...

Two recent publications in the January, 2000 issue of J. Nat. Can. Inst. (Djordjevic et al . and Wilkenfeld et al .) continue to highlight the confusion surrounding the intent of the FTC method for determining 'tar' and nicotine yields of...

An international collaborative study was performed to compare several analytical methods for the determination of nicotine in tobacco that are in current use around the world. Five nicotine methods were evaluated and compared, specifically...

Taking in account recent progress in ultrasonic and microwave extraction techniques, the applicability of such methodologies to the extraction of tobacco alkaloids from cured tobacco was optimised and compared with the conventional ones, namely steam...
