Cis-3-hexenol adds a green, foliaceous taste and a smell of chlorophyll to the tobacco smoke (Leffingwell et al. 2005a, Connolly 2004).Ĭis-3-hexenol is added to increase the organoleptic characteristics of tobacco and it has a characteristic smell of newly mown grass (Alford and Johnson 1970). The same agents may also be used to target the individual product at certain target groups (Carpenter et al. Less resistance may be encountered from persons that do not smoke, and at the same time greater pleasure for the smoker may be created. Reducing side-stream emissions is based on encapsulating the smoke in an impermeable cone using different types of additives such as potassium succinate, potassium citrate and magnesium carbonate.īy combining the use of additives and the look of the tobacco product, greater acceptance of the smoke may be created. This has an effect on particle size particles become smaller and therefore do not easily scatter light and become less visible. Reduced visibility of side-stream smoke is accomplished by the addition of magnesium oxide, magnesium carbonate, sodium acetate, sodium citrate and calcium carbonate to the wrapper (cigarette paper). vanillin, benzaldehyde, bergamot oil, cinnamon/cinnamon extract, coffee extract and nutmeg oil) modify side-stream odour. cinnamic aldehyde, pinanediol acetal) produce slightly sweet, spicy, clean, fresh, and less cigarette-like aroma. polyanethole provided a noticeable fresher, cleaner and less irritating cigarette side-stream aroma, while others (e.g. These compounds have rather low odour thresholds, and are subsequently easily picked up, while they elicit no trigeminal nerve response. Methods to neutralize or reduce lingering smoke odour include addition of acetylpyrazine, anethole and limonene to modify the side-stream odour. These strategies include reducing smoke odour, and reducing side-stream smoke visibility and emissions. (2000) examined tobacco industry patents covering the function of environmental tobacco smoke masking. ![]() 2000, Ling and Glantz 2005).Ĭonnolly et al. The smell of the smoke may be also changed so that it is also more attractive and less irritating (Connolly et al. This may be attained with additives which make the smoke whiter and more attractive to people seeing the smoke. In order to make the smoke more attractive to the smoker, but also to other people in the proximity of the smoker, it is important that the smoke is appealing and not annoying. to prevent them from drying out, and consequently increase the shelf life of the products.Įxamples of additives include: glycerol, propylene glycol and sorbitol.Īppearance, smell and irritation of tobacco smoke Humectants are added to tobacco products to retain the water, i.e. Preservation of humidity of the tobacco product Other reasons for using additives are to produce a unique product, typical in taste and markedly different from competitor products, and to maintain the stability of the taste of the product. One of the reasons to use additives is to attract the smoker to a specific product and to promote/encourage (young) people to start using the product. by means of a cool, sweet and mild smoke, as well as causing less irritation in the lungs).įor many additives, attractiveness depends on multiple functions which may be difficult to distinguish clearly. ![]() appearance of the product, white and full smoke) or by making it easier to start smoking (e.g. This may be attained by creating a better experience of the product (e.g.
