| Summary: | Smokeless tobacco products are products that do not require a pyrolysis process and / or the production of tobacco aerosol (smoke) at the time of use. In the absence of data on the toxicological risks of smokeless tobacco, their consumption is potentially on the rise. The variety of non-smoking tobacco products creates certain problems in identifying chewing tobacco and sucking tobacco (banned for sale in the Russian Federation) as products that are identical in terms of physiological effects, method of consumption, and component composition. A methodology has been developed for a comprehensive assessment of non-smoking products, including the determination of consumer properties and technological indicators by instrumental methods, as well as the determination of the level of toxic components (nicotine, TSNA, B(a)P). The difference between the types of smokeless tobacco is mainly in the granulometric composition of the product: snus – finely ground tobacco, chewing tobacco – snatches of tobacco with a removed middle vein. Identification indicators have been determined: the presence of raw tobacco, the size of its particles and the number of large fragments in the finished product. The presence of raw tobacco can be determined by optical microscopy and/or luminescent analysis, and the quantitative content can be determined by sieve analysis. The quantitative content of the coarse fraction in chewing tobacco (not less than 15 %) is the main indicator of the product. The use of the fractionation method makes it possible to differentiate between sucking and chewing tobacco. A «Method for determining the fractional composition of non-smoking tobacco products for oral consumption by the method of sieve analysis» was developed (Certificate No. 022-01.00281-2013-2022). To certify the methodology, a set of studies was carried out, the data were obtained as a result of five parallel measurements by three performers for each sample. The technique is registered in the State Register of Measuring Instruments (FR.1.31.2022.43935 of 09/02/2022). Technological indicators of SLT samples were established: humidity (11,4-53,3) %, pH level 5,7-9,7, coarse fraction content (0,4-56,9) %, dust fraction content (0,2-76,3) %. The results of identification of commercial samples of a segmental product are presented. |
