Embodiment

[0038] Example: Screening the Influencing Factors of Vanillin and Ethyl Maltol on the Content of Special Smoke Components in Cigarettes

[0039] 1 Determine the test index as the change value of the content of special smoke components in cigarettes

[0040] The content of special smoke components in cigarettes includes the content of phenol in mainstream smoke, the content of crotonaldehyde in mainstream smoke, the content of ammonia in mainstream smoke, and the content of tobacco-specific N-nitrosamine NNK in the total particulate matter of mainstream smoke etc.; the change value of the content of special smoke components in cigarettes, that is, the difference between the content of a specific smoke component in cigarette samples with exogenous additives minus the content of certain special smoke components in solvent control cigarette samples;

Abstract

The invention relates to method of screening exogenous additive factor influencing the content of a cigarette special smoke component and belongs to the technical field of tobacco. The method comprises: confirming a test index; confirming a test factor; selecting within a horizontal scope; choosing an orthogonal design to conduct an experiment design; drawing up a testing program; handling the test result by a range analysis method and a variance analysis method; screening a key control factor for sample preparation. The method provided by the invention has the advantages that a scientific and feasible system research method is provided; the experiment period is shortened, and the influence law of each factor on the content of the cigarette special smoke component can be rapidly, efficiently, economically and accurately sought and confirmed; the highly significant impact factor or significant impact factor of an exogenous additive to the content of the cigarette smoke component can bescreened by virtue of variance analysis; through controlling the screened factor, the sample preparation is regulated, errors are reduced, and the reliability and scientificalness of the test result and conclusion on the follow-up exogenous additive factor influencing the content of the cigarette smoke special component are ensured.

Description

Technical field: [0001] The invention relates to a method for screening the influence factors of exogenous additives on the content of special smoke components in cigarettes, and belongs to the technical field of tobacco. Background technique: [0002] Paschke et al. reviewed 189 published documents, covering more than 300 kinds of additives on the effects of flue gas properties. They found wide variation in the effects of additives on the chemical composition of the smoke, emphasizing the need for standard methods to assess the effects of additives on smoke [1] . [0003] British American Tobacco Richard R.Baker et al found that in most cases, after the tobacco flavor components are added in the maximum or excess amount (generally the addition amount is ppm level) in its commercially available cigarettes, its effect on the smoke composition Compared with the control, there is no significant difference in the effect of the score, and it can often be found that some flavor ...
