Embodiment 1

[0042] (1) Data discretization processing:

[0043] Using different ratios of sodium citrate, potassium citrate, sodium malate and potassium malate as combustion-accelerated additives in cigarette paper, and the designed addition range of the mixed combustion-accelerated agent was 1.0-3.5%, 19 groups of cigarette samples were rolled with the cigarette paper . 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]

[0046] The discretization of the combustion aid ions adopts the median method. Specifically, first calculate the median of the combustion aid and the ion content of the combustion aid, the value of the sample smaller than the median is converted to 0, and the value of the samp...

Abstract

The invention discloses a method for constructing a predicating model of the release amount of NNK in cigarette smoke based on a combustion-supporting agent and belongs to the technical field of harmful influence of cigarette additives on cigarettes. The method comprises the following steps of: after the combustion-supporting agent content is resolved into combustion-supporting agent ion content, processing data by use of a discretization method, further screening an important combustion-supporting agent and combustion-supporting agent ions by use of a grouped sample comparison algorithm, and constructing a mathematic model of predicating a quadric function of the release amount of NNK in the cigarette smoke according to the screened important combustion-supporting agent and / or combustion-supporting agent ions. The method is simple and practical; the constructed model is relatively high in predication model; a new method is provided for constructing the model for predicating the release amount of NNK in the cigarette smoke according to a citrate and malate combustion-supporting agent system or other combustion-supporting agent systems.

Description

technical field [0001] The invention belongs to the 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 NNK. At the same time, the invention also relates to constructing and screening accelerants and / or accelerant ions A predictive model for NNK delivery in cigarette 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, w...
