Problems solved by technology

[0004] However, the focus of research on heated cigarettes is mainly in the fields of research and development of smoking utensils and cigarette stick design, and there are few reports on the stability of raw materials for heated cigarettes. Or use an expensive smoking machine to imitate the method of smoking a cigarette to measure the amount of smoke, which requires expensive and complicated instruments and complicated operations. Therefore, it is very important to develop a convenient, concise and accurate method for judging the stability of heated cigarette raw materials. important

Abstract

The invention discloses a method for judging the stability of a heated cigarette raw material. The method for judging the stability of the heated cigarette raw material is obtained according to thermogravimetric detection data of the heated cigarette raw material, and specifically comprises the following steps: 1) detecting a cigarette sample by using a thermogravimetric analyzer; 2) sampling N or more than N cigarette samples for each cigarette sample; 3) detecting each extracted cigarette sample for M times or more, and calculating an average value; 4) calculating a discrete coefficient or a relative standard deviation of a detection result; and 5) judging the stability of the heated cigarette raw material according to the discrete coefficient or the relative standard deviation. The heated cigarette raw material is subjected to thermogravimetric analysis through the thermogravimetric analyzer, and discrete coefficients or relative standard deviations of multiple sampling detection results are compared and analyzed, so that the stability of the heated cigarette raw material is judged. The method is easy to operate, good in stability and capable of rapidly judging the stability of the heated cigarette raw materials.

Description

technical field [0001] The invention relates to a stability analysis technology for heated cigarette raw materials, in particular to a method for judging the stability of heated cigarette raw materials based on thermogravimetric analysis. Background technique [0002] Heated cigarettes are a new type of tobacco product. The biggest feature is that there is no need to ignite the cigarettes. The tobacco shreds are heated at a temperature far lower than that of traditional cigarettes to generate smoke to meet the smokers’ sensory needs. Heated cigarettes are among the new tobacco products that are closest to traditional cigarettes in terms of usage and flavor characteristics. [0003] In recent years, heating cigarettes have developed very rapidly, and the products are rich and diverse, and the sales volume in the international market has increased year by year. At home and abroad, various tobacco companies are investing a lot of manpower and material resources in research and...
