Embodiment 1

[0043] (1) Data discretization processing:

[0044] Sodium citrate, potassium citrate, sodium malate and potassium malate in different proportions were used as combustion-accelerating agents in cigarette paper, and the design addition range of the mixed combustion-accelerating agent was 1.0-3.5%, and then 19 groups of cigarettes were rolled with the cigarette paper sample. The content of combustion aid was determined by conductivity method, the content of citrate and malate by ion chromatography, and the content of potassium and sodium ions by flame photometry. The results are shown in Table 1.

[0045] surface Combustion enhancer, ion content of combustion enhancer and HCN release in cigarette smoke

Abstract

The invention discloses a method for establishing a model for predicting the release amount of HCN in the smoke of cigarettes by using combustion improvers and belongs to the technical field of research into the harmfulness and influence of cigarette additives to cigarettes. The method comprises the following steps: decomposing the content data of the combustion improvers into the content data of ions of the combustion improvers, processing the data by discretizing, selecting an important combustion improver and ions of the combustion improver by comparing grouped samples, and establishing the mathematic model for predicting the quadratic function of the release amount of HCN in the smoke of cigarettes by using the selected important combustion improver and / or ions of the combustion improver. The method disclosed by the invention is simple and practical, the established model has high predication precision, and the method is a new method for establishing a model for predicting the release amount of HCN in the smoke of cigarettes by using citrate and malate combustion improver systems or other combustion improver systems.

Description

technical field [0001] The invention belongs to the technical field of the harmful effects of cigarette additives on cigarettes, and in particular relates to a method of using data discrete variable screening to investigate the influence of combustion accelerants and accelerant ions on HCN. A predictive model for the impact of HCN emissions in smoke. Background technique [0002] In recent years, with the gradual increase of people's attention to smoking and health, the hazard evaluation of cigarettes has become one of the hot research topics in the tobacco industry at home and abroad. In 2009, Xie Jianping established a cigarette hazard assessment based on the release of seven harmful components (including CO, HCN, NNK, HH3, benzopyrene, phenol, and crotonaldehyde) in mainstream cigarette smoke and the results of smoke toxicology tests. Index—the cigarette hazard index H value, which for the first time links the release amount of harmful components in cigarette smoke with ...
