Method for t detection of influence degree of additive on special smoke indexes of cigarette

Abstract

The invention relates to a method for t detection of an influence degree of an additive on special smoke indexes of a cigarette, belonging to the technical field of the tobacco. The method comprises the following steps of: determining test indexes as special smoke indexes of the cigarette, mainly comprising the contents of phenol, crotonaldehyde, hydrocyanic acid, ammonia and NNK ([4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone]) in main stream smoke; selecting the concentration of the additive; selecting reference test design for experimentation; processing test results, namely examining an independent sample t; and determining the influence degree of the additive on the special smoke indexes of the cigarette according to the examination result of the independent sample t. The method, in the application process, has the following advantages that: whether the influence of the additive on the special smoke indexes of the cigarette is obvious can be determined, and the determination and conclusion are scientific and reliable; and the method has great realistic significance on determining the efficacy of the harm-reducing and tar-decreasing additive and improving the quality safety of the cigarette product.

Description

Technical field: [0001] The invention relates to a t test method on the degree of influence of additives on special smoke indexes of cigarettes, and belongs to the technical field of tobacco. Background technique: [0002] How to reduce harmful substances in cigarette smoke through effective means has always been a topic of common concern inside and outside the industry, and it is also the main task and focus of the industry's scientific and technological research. At the same time, this is also a problem that must be faced and solved in the process of developing "Chinese-style cigarettes" in our country Focus. At present, China Tobacco has selectively reduced the release of carbon monoxide, hydrogen cyanide, nitrosamine NNK, ammonia, benzo[a]pyrene, phenol and crotonaldehyde in cigarette smoke as a criterion for evaluating the hazards of cigarettes. Important indicators [1，2] , and listed how to reduce these indicators as the main direction and important project of scient...

AI Technical Summary

Problems solved by technology

[0004] At present, the significance inference of many relevant studies is obtained by simple visual comparison with control cigarettes [4～13] , the impact of additive concentration changes on cigarette smoke components cannot be distinguished from the fluctuations caused by experimental errors, which affects the accurate determination of the additive’s harm reduction and tar reduction efficacy

So far, there have been no public reports at home and abroad on the use of independent sample t-tests to analyze test data and to judge the influence of additives on special cigarette smoke indicators based on the analysis results
