Background Art
[0002] Heated cigarettes are a new type of tobacco product that uses external heat sources to control the heating temperature of the tobacco core, which is mainly composed of tobacco raw materials, thereby releasing aerosols. Heated cigarettes have become the focus of tobacco companies' product research and development due to their reduced harmfulness, and have also attracted the favor of some consumers for related products. Heated cigarette cores come in a variety of forms, such as thin sheets, particles, and natural tobacco shreds. However, no matter what form of core, a considerable proportion of smoke-generating agents are often applied to increase the concentration of smoke aerosols and promote the release of flavor substances in the core. However, when designing heated cigarette products, it is often shown that the amount of smoke released by the core made of different tobacco raw materials is different, which seriously affects the consumer experience.
[0003] How to evaluate the smoke volume of heated cigarette products and tobacco raw materials has become a matter of great concern to product designers. CN117054478A discloses a method for characterizing the smoke volume of heated cigarettes based on a smoke volume voltage measurement module; CN116223682A discloses an evaluation method for detecting the smoke release performance of a smoke-generating agent by using a smoking machine combined with a photoelectric sensor, an ion sensor, a gas-sensitive sensor, etc.; Si Xiaoxi et al. (Journal of Tobacco Science, 2021, 27(6): 1-9) used the DMS500 fast particle size spectrometer online analysis system to detect the volume concentration of aerosol particles.
[0004] The above-mentioned methods for evaluating the smoke volume of heated cigarettes all involve advanced spectral analysis instruments and focus on the performance evaluation of heated cigarette products. Therefore, it is a technical problem to be solved in this field to provide a method for evaluating the smoke volume release level of heated cigarette tobacco raw materials with simple operation and low detection cost, so as to accurately judge the smoke volume release level of heated cigarette tobacco raw materials. Summary of the invention
[0005] In order to solve the above technical problems, the present invention provides an evaluation method for the smoke release level of heated cigarette tobacco raw materials. The present invention realizes the performance evaluation of the smoke release level of heated cigarette tobacco raw materials based on the release efficiency of the smoke generating agent. The evaluation method is simple to operate and the results are reliable. It provides a new means for the quality evaluation of heated cigarette tobacco raw materials and a new idea for the prediction and evaluation of the smoke amount of heated cigarette tobacco raw materials.
