Embodiment 1

[0029] 1. Select 5 grams each of 1 standard formula sample and 7 heated cigarette formula samples, pass through a 100-mesh sieve respectively, and pass through a constant temperature and humidity environment of (22±1)°C and relative humidity of (60±2)% for 48 Hour.

[0030] 2. Before sample analysis, set the thermogravimetric analyzer to keep at 900°C for 10 minutes, so that the impurities in the furnace body can be removed, and the empty crucible is used as a reference. Weigh (5.00±0.05) mg sample and place it in a thermogravimetric platinum crucible. The heating program is as follows: initial temperature 30°C, heating rate 10°C / min, end temperature 350°C, and test at 50mL / min air flow. The balance sensitivity is not lower than 0.1μg, and the curve resolution is not lower than 50 million resolution points.

[0031] 3. Obtain the 350°C thermogravimetric curves of the heated cigarette formula sample (sample) and the standard formula sample (standard product), and obtain the di...

Abstract

The invention discloses a method for evaluating a heated cigarette formula based on material heated mass change information. The method comprises the following steps: (1) preparing a plurality of heated cigarette formula samples and a standard formula sample; (2) thermogravimetric experiment; (3) processing the thermogravimetric curve to obtain a differential weight loss curve; (4) calculating the similarity of differential weightlessness curves of a plurality of heated cigarette formulas and a standard formula; and (5) evaluating a plurality of heating cigarette formulas. According to the method, subjective factor influence and difference caused by traditional manual sensory evaluation are avoided. The method is more objective, efficient, good in repeatability, high in sensitivity and simple to operate.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to a method for evaluating the formula of heated cigarettes by using the principal component-Mahalanobis distance analysis method based on the information on the change of the heated mass of the substance. Background technique [0002] Heated cigarettes, also known as heat-not-burn tobacco products, are a new type of tobacco products. Heated cigarettes use a special heating source to heat the tobacco material. When heating, the nicotine and flavor substances in the tobacco material are volatilized to produce smoke to meet the needs of smokers. Different from traditional cigarettes, heated cigarettes are only heated but not burned, which completely changes the smoke generation and transmission mechanism, reduces the harmful components produced by high-temperature combustion and cracking of tobacco, and effectively improves safety. [0003] In a mixed system containing tw...
