Abstract

The invention relates to a method for treating buccal tobacco sample and a method for detecting aldehyde substances of buccal tobacco, and belongs to the technical field of smoke-free tobacco productchromatographic analysis and detection. The method for treating the buccal tobacco sample comprises the following steps: adding an acidity pH regulator, a derivatization reagent and an extracting agent into the buccal tobacco sample sequentially and mixing uniformly, leaving to stand and layering, and taking the upper layer of organic phase as a to-be-detected sample, wherein the volume of the extracting agent corresponding to 1 g of buccal tobacco is 8 to 15 ml. According to the method for treating the buccal tobacco sample, leaching of the aldehyde substances of the buccal tobacco can be accelerated, the reaction time of the aldehyde substances and the derivatization reagent of the buccal tobacco is shortened, the product after reaction is extracted to enter the organic phase, the analysis and detection time is further shortened, the loss of the aldehyde substances in the analysis and detection process is reduced and the accurate degree of analysis and detection is increased.

Description

technical field

[0001] The invention relates to a processing method for snus samples and a detection method for aldehyde substances in snus, belonging to the technical field of chromatographic analysis and detection of smokeless tobacco products. Background technique

[0002] Smokeless tobacco products are a kind of tobacco products that consume tobacco through non-combustion methods. There are many types, and the mainstream product on the market is snus. Snus refers to the form of smokeless tobacco products that are consumed by snuffing. There are two main types, namely Swedish snus (Snus) and American snuff (Moist snuff). Swedish tobacco is a kind of wet tobacco powder with Swedish style, which is usually made of tobacco powder with a certain particle size mixed with an appropriate amount of flavoring substances, flavoring agents, water, humectants and acid-base regulators through heat treatment. The moisture content is generally between 30% and 60%, and there are two typ...
