The pyrolytic formation of formaldehyde from sugars and tobacco

Carbohydrate pyrolysis mechanisms from isotopic labeling

“…Formaldehyde formation from various sugars in a cigarette smoking context has recently been discussed, mostly in terms of increased delivery of formaldehyde into mainstream smoke when sugar levels are increased in the tobacco filler [42,43]. The mechanisms of formation were not discussed, and isotopic labeling was not used in this work.…”

Pyrolysis behavior of pectin under the conditions that simulate cigarette smoking

“…However, as seen from these literatures, there has been little emphasis on the pyrolysis of pectin under the conditions that could simulate cigarette smouldering and puffing. It has been found that unless pyrolysis experiments are performed under dynamic conditions that can simulate tobacco burning, results can be obtained which have little resemblance to those obtained during cigarette smoking [13,14]. Recently, a research group, consisted of relevant tobacco scientists from the research centers of cigarette manufacturers operating in Philip Morris, British American Tobacco, Japan Tobacco International, Imperial Tobacco Ltd., etc., has established a set of pyrolysis conditions which can predict the pyrolytic behavior of tobacco ingredients during smoking.…”

Smoke Chemistry

“…One exception on the formation of smoke constituents by additives is formaldehyde, which is generated as a primary pyrolysis product from sugars and saccharides that are naturally present in tobacco and also commonly used as tobacco additives [17] . Additives may signifi cantly increase mainstream formaldehyde levels depending on their type and applied concentration.…”
