Problems solved by technology

In the process of research on cigarette combustion enhancers, a large number of studies have focused on the relationship between the content of different cigarette combustion enhancers and the release of 7 harmful components and the H value in cigarette smoke. There are few studies on this aspect, especially in judging the influence of combustion accelerants and accelerant ions on the H value in cigarette smoke, and based on this, there have been no reports on the establishment of a H value prediction model in cigarette smoke

Embodiment 1

[0041] (1) Data discretization processing:

[0042]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.

[0043] surface Combustion enhancer, ion content of combustion enhancer and H value in cigarette smoke

[0044]

[0045] The discretization of the accelerant and accelerant 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...

Abstract

The invention discloses a method for constructing a H value prediction model in cigarette smoke based on a combustion accelerant, and belongs to the technical field of the harmful effects of cigarette additives on cigarettes. After the present invention decomposes the content of the combustion-supporting agent into the content of the combustion-supporting agent ion, a discretization method is used to process the data, and then the importance of the combustion-supporting agent and the combustion-supporting agent ion is screened with a grouping sample comparison algorithm, and the combustion-supporting agent and / or the combustion-supporting agent according to the importance of the screening A cubic function prediction mathematical model of the H value in cigarette smoke was constructed using agent ions. The method is simple and practical, and the prediction accuracy of the established model is high, which provides a new method for the establishment of the prediction model of H value in cigarette smoke with citrate and malate combustion enhancer system or other combustion enhancer systems.

Description

technical field [0001] The invention belongs to the technical field of the influence of cigarette additives on the harmfulness of cigarettes, and specifically relates to a method of screening data discrete variables to investigate the influence of combustion enhancers and combustion enhancer ions on the H value in cigarette smoke. At the same time, the invention also relates to the construction of A predictive model of oxidizers and oxidizer ions on the H value 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. How to link the harmful components of mainstream cigarette smoke with their harmfulness has always been a world problem that has not been solved by the tobacco industry for a long time. In 2009, Xie Jianping established a cigarette hazard assessment based on the...
