Embodiment 1
[0017] Isophorone pyrolysis experiment: Accurately weigh 0.5-1.0g sample, dissolve it with ethanol, and transfer it to a 100ml volumetric flask. A certain amount of quartz glass fiber is installed in the quartz glass tube, and 5-10
[0018] μl sample solution is injected onto the quartz glass fiber in the quartz cracking tube. Put it in the lysis filament of the lysis probe, put the lysis probe into the lyser, and start the lysis. The temperature at the interface between the cracker and the gas chromatograph is 250°C. Cracking heating program: Cracking start temperature is 50°C-100°C, keep for 2s, raise the temperature to the set temperature at a heating rate of 5°C-10°C / ms, keep for 20s. Chromatographic column HP-FFAP (30m*0.25mm*0.25μm), inlet temperature 250°C, constant flow 0.6ml / min, split ratio 10:1. Furnace temperature rise program: start at 50°C-80°C, keep for 1min-2min, raise the temperature to 220°C at a heating rate of 5°C-10°C / min, and keep for 10min-30min.

Abstract
The invention discloses a method for evaluating the influence of the perfume monomer on cigarettes by adopting the thermal pyrolysis experiments, which is characterized by comprising the following steps: perfume monomer samples of a certain amount are sampled, dissolved by solvent and volume-limited, the sample solution is injected in the glass fiber of a quartz glass tube by a sampling needle, then pyrolysis is carried out in a pyrolysis apparatus, the generated pyrolyzate is carried out GC / MS analysis, and the influence of the perfume monomer on the cigarette smoke after the perfume monomer is added into the cigarette is evaluated according to the analytic determination result of the pyrolyzate. The invention has the advantages that: the perfume monomer is carried out thermal pyrolysis by simulating the temperature condition in the cigarette combustion process, and GC / MS is adopted to carry out analysis on the pyrolyzate, thus evaluating the influence of the perfume monomer on the smoke composition after the perfume monomer is added into the cigarette for combustion, and the method has simple operation and low cost. The method can comprehensively evaluate the influence of the perfume monomer on the flavor components in the smoke composition and the burst size of harmful ingredients after the perfume monomer is added into the cigarette for combustion, and has important guidance meaning for the application of the perfume monomer on the cigarette.
Description
technical field [0001] The invention relates to a method for estimating the effect of spice monomers on cigarettes by means of thermal cracking experiments. This method can be used to comprehensively evaluate the impact of flavoring monomers added into cigarettes on the release of flavor components and harmful components in smoke components after burning. Background technique [0002] In the process of cigarette product design and production and processing, in order to improve product quality, improve the taste of cigarettes, and endow products with unique style characteristics, enterprises need to add various spices. The use of these spice additives is one of the important factors affecting the quality and safety of cigarette products. During the burning process of cigarettes, the additives in cigarettes and the chemical components of shredded tobacco have undergone a series of complex reaction processes such as distillation, cracking, synthesis, polymerization, and conden...
