Embodiment 1

[0042] (1) Data discretization processing:

[0043] Using different proportions of sodium citrate, potassium citrate, sodium malate and potassium malate as the combustion-accelerating agent of cigarette paper, and the design addition range of the mixed combustion-accelerating agent is 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.

[0044] Table 1 Combustion promoters, content of combustion promoter ions and NNK release in cigarette smoke

[0045]

[0046]

[0047] 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, ...

Abstract

The invention discloses a construction method of a predication model for an ammonia releasing amount in cigarette smoke based on a combustion-supporting agent and belongs to the technical field of cigarette perniciousness influences caused by a cigarette additive. The construction method comprises the following steps: after decomposing combustion-supporting agent content into combustion-supporting agent ion content, processing data by adopting a discretization method, so as to screen an important combustion-supporting agent and combustion-supporting agent ions by using a grouped sample comparing algorithm; and constructing a secondary function predication mathematical model of the ammonia releasing amount in the cigarette smoke according to the screened important combustion-supporting agent and / or the combustion-supporting agent ions. The method is simple and practical, and a new method is provided for establishing the predication model for the ammonia releasing amount in a citrate and malate combustion-supporting agent system or other combustion-supporting agent cigarette smoke.

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 ammonia. At the same time, the invention also relates to constructing and screening accelerants and / or accelerant ions A predictive model for ammonia 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 ...
