Method for simulating and measuring thermal migration quantity of formaldehyde and acetaldehyde in cigarette blasting beads to smoke

Abstract

The invention relates to a method for simulating and measuring the thermal migration quantity of formaldehyde and acetaldehyde in cigarette blasting beads to smoke, and belongs to the technical fieldof safety evaluation of cigarette materials. The method comprises the following steps: firstly, a hot-air blower is turned on, and after the temperatures of an air outlet and an air outlet are stabilized, a to-be-detected blasting bead is wrapped with acetate fibers and punctured, and the blasting bead is quickly put into a purging pipe; a smoking machine is started for smoking, an air flow passesthrough the purging pipe to purge out formaldehyde and acetaldehyde which can migrate in the blasting bead in the smoking process of the smoking machine, and the formaldehyde and the acetaldehyde arecaptured through a catcher; and after purging is completed, the catcher is taken down, the catcher is eluted with a polar organic solvent in the direction opposite to the inflow direction of the airflow, filtering is conducted, liquid chromatography is adopted for filtrate analysis, and the mobility is calculated. The method provided by the invention can truly simulate elution of cigarette smokeflow to the blasting bead and accurately determine the migration quantity of formaldehyde and acetaldehyde residues in the blasting bead to cigarette smoke, thereby objectively evaluating the safetyof the formaldehyde and acetaldehyde residues in the blasting bead.

Description

technical field [0001] The invention belongs to the technical field of safety evaluation of cigarette materials, and in particular relates to a method for simulating and measuring the thermal migration of formaldehyde and acetaldehyde in cigarette popping beads to smoke. Background technique [0002] As consumers' demand for personalized cigarette products becomes increasingly strong, puffballs are widely used in cigarette products, and the sales volume of cigarette products containing puffballs is increasing day by day. Popping bead cigarettes are implanted with one or more easily pinched flavor capsules in the mouth stick during the production process of cigarettes, so as to realize the artificial and controllable release of characteristic flavors in the process of smoking cigarettes, so as to highlight the individual characteristics of the product , to improve the smoking quality of cigarettes. [0003] Cigarette popping beads are divided into two parts: the core materia...

AI Technical Summary

Problems solved by technology

However, the determination of formaldehyde and acetaldehyde in the current popping beads is more limited to the popping beads themselves, separated from the actual smoking process of cigarettes, and cannot reflect the actual contact with the human body

Although there are also some reports on detection devices and detection methods for the migration of filter stick additives; but the structure of the device is too complicated, the operation is inconvenient, and the measurement results have large deviations (such as CN201810467715.6); the design of the characteristics of low-molecular aldehyde compounds is not considered Targeted capture leads to large loss of components to be measured and affects analysis results (such as CN201429591Y and CN203365266U) and other issues
