Abstract
The invention provides a method for detecting menthol in smoke-free tobacco products. The method is capable of detecting the content of the menthol in the smoke-free tobacco products by virtue of a capillary column gas chromatography-flame ionization detector (GC-FID) method and mainly comprises the following steps: (1) pre-treating samples; (2) preparing a standard menthol solution; (3) qualitatively detecting the samples in an extraction solution; (4) quantitatively detecting the samples in the extraction solution; and (5) detecting the content of the menthol in actual samples. The method for detecting the menthol in the smoke-free tobacco products is stable, accurate, simple, convenient, reliable, high in recovery rate, high in repeatability and high in practicability, The content of the menthol in mint smoke-free tobacco products and formula tobacco powder can be effectively controlled; the technical guarantee can be provided for developing the safe and healthy smoke-free tobacco products which are suitable for tastes of consumers in China.
Description
technical field [0001] The invention belongs to the technical field of chemical analysis and detection, and in particular relates to a method for determining menthol in smokeless tobacco products. Background technique [0002] Menthol, also known as hexahydrothymol, commonly known as menthol, and chemically named 1-methyl-4-isopropyl-cyclohexan-3-ol, is an extract from plants and can be isolated from natural peppermint oil. It can also be artificially synthesized from citronellal or thymol. Menthol has a melting point of 42-43°C and a boiling point of 216°C. It is a colorless columnar or needle-like crystal at room temperature. Menthol has a strong mint aroma and cool taste, and is widely used in cosmetics, food, and medicine industries; in the tobacco industry, a small amount of menthol is added to shredded tobacco to make mint-flavored cigarettes, which will produce a refreshing feeling when smoking, and can effectively reduce smoke. The burning sensation of qi, and stim...
