Abstract

The invention discloses a method for measuring content of vanillin and ethyl vanillin in an additive for cigarettes. The method is used for analyzing vanillin and ethyl vanillin in the additive for cigarettes by using a gas chromatograph-selected ion monitoring mass spectrometer (GC / MS) taking naphthalene as an internal standard, and comprises steps of interior label solution preparation, sample treatment, standard working solution preparation and sample measurement, and has the characteristics of rapid measurement, simplicity and convenience in operation, high recycling rate, good repeatability and the like. By adopting the method, the vanillin recycling rate is 96.7-99.2%, the recycling rate of the ethyl vanillin is 97.5-103.0%, and the RSD of the vanillin is 3.86-4.86%, and the RSD of the ethyl vanillin is 1.89-2.98%.

Description

technical field [0001] The invention belongs to the technical field of physical and chemical detection of tobacco additives, and mainly relates to a method for determining the content of vanillin and ethyl vanillin in tobacco additives, specifically using gas chromatography-selected ion monitoring mass spectrometry (GC- MS) Method for direct determination of vanillin and ethyl vanillin content in tobacco additives. Background technique [0002] Vanillin, also known as vanillin, scientific name 3-methoxy-4-hydroxybenzaldehyde; ethyl vanillin, scientific name 3-ethoxy-4-hydroxybenzaldehyde. Both are white or slightly yellow crystalline powder, slightly soluble in water, soluble in ethanol, glycerin, ether, chloroform and spices, both have vanilla aroma and strong milky aroma, and the aroma of ethyl vanillin is 3-4 times that of vanillin, both of which are widely used as fixatives, flavoring agents, food and blending spices, adding an appropriate amount of vanillin and ethyl v...
