Transfer Behavior of Characteristic Components of Milk-flavored Gel Filter Rod in Cigarettes
In order to study the flavoring effect of milk-flavored gel filter rod in cigarettes,a GC-MS analytical method was established,the pre-treatment conditions were optimized,and the transfer rates of the characteristic components in milk-flavored gel filter rod cigarettes were investi-gated.The results showed that the optimal extraction conditions:anhydrous ethanol was used as the solvent,the extraction volume was 10 mL,and the ultrasonic extraction time was 60 min;the sample adding recovery rates of five characteristic components (vanillin,ethyl vanillin,vera-traldehyde,anisyl alcohol,anisyl acetate ) in the milk-flavored gel filter rod were 94. 1％-104. 1％,and the detection limits were 0. 11-8.23 μg/mL,with a quantification limit of 0.25-27.42 μg/mL.The transfer rates of the five characteristic components were divided into three gradients.The transfer rates of vanillin and ethyl vanillin to the mainstream flue gas particulate matter were higher,at 8.44％ and 8.14％,re-spectively,followed by anisyl alcohol (5.42％) and anisyl acetate (4.35％),the transfer rate of veratraldehyde was the lowest,at 2.44％.The filter tip retention rate of the five characteristic components was 85.31％-90.37％,indicating that most of the characteristic components were trapped in the filter tip under the gel flavoring mode. The vanillin content in the filter tip and the transfer rate of vanillin in the mainstream smoke particles decreased rapidly 180 days before being placed in the natural environment,and showed a gradual decline trend 180-360 days after being produced,indicating that 180 days after being produced was the best time for smoking milk-flavored gel filter rod cigarettes. Under the condition of constant temperature and humidity,the vanillin content in the filter tip and the transfer rate of vanillin in the particulate matter of mainstream smoke were higher than those in the natural ventilation environment,indicating that milk-flavored gel filter rod cigarettes were best stored in the environment with relatively constant temperature and humidity.
