Abstract

The invention relates to a method for researching the release of nitrosamines in the oral cavity of oral smokeless tobacco products. Determination of oral release of nitrosamines, in vitro test simulation and other steps. The present invention uses in vivo experiments to determine in vitro research parameters, and uses a fully simulated chewing machine to test samples in vitro. The device used can completely simulate the state of human oral cavity smoking smokeless tobacco products. The temperature can be adjusted, and the controllability is strong, the stability is high, and the operation is simple. The research method of the present invention can well avoid the influence of subjective and objective factors brought about by traditional artificial tasting, avoid the ethical and moral restrictions of a large number of people's experiments, save the experiment cost and reduce the health hazards caused by human experiments , suitable for batch studies of samples.

Description

technical field

[0001] The invention belongs to the technical field of analysis of oral smokeless tobacco products, and in particular relates to a method for studying the oral release of nitrosamines peculiar to oral smokeless tobacco products. The method can be used to study and analyze oral smokeless tobacco products Tobacco-specific nitrosamine leaching from smoke tobacco products. Background technique

[0002] Smokeless Tobacco products (STPs for short) refer to tobacco products that are smoked directly through the mouth or nose without burning. Compared with traditional cigarettes, they have fewer harmful components and are less harmful; at the same time, they do not produce second-hand smoke. To a certain extent, it can alleviate the contradiction between smoking ban and smoking in public places, and satisfy the physiological needs of smokers to a certain extent.

[0003] Smokeless tobacco products come in various forms such as snus in pouches, snus and chewing tobacc...
