Technical Field

[0001] The present invention relates to the technical field of heated cigarettes, and in particular to a visualization method for a moisture content indicating label of a heated cigarette. Background Art

[0002] The moisture content of tobacco shreds in tobacco products is an important physical indicator of tobacco and its products, and has a significant impact on tobacco storage, processing performance, cigarette appearance and smoking taste. Heated cigarettes are a new type of tobacco product, and their shreds are mainly composed of thin sheets mixed with a large amount of glycerin and volatile spices, which makes heated cigarettes very easy to absorb water, thus affecting the sensory quality of heated cigarettes.

[0003] During the production process, the moisture content of heated cigarettes is mainly monitored quickly using physical, chemical and instrumental technologies. However, it is also very necessary for consumers and transporters to truly and conveniently understand the changes in the moisture content of heated cigarette tobacco.

[0004] At present, there are humidity indicator cards on the market for high-end electronic devices and instruments such as electronic components and precision optical parts. The humidity conditions in the sealed package can be directly visually identified through the color display on the humidity card. However, this type of humidity indicator card cannot truly reflect the water absorption of the product. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a visualization method for a moisture content indicator label for heated cigarettes. It establishes a mathematical model between the indicator label and the moisture content to achieve visual direct reading of the moisture content of heated cigarette tobacco, thereby facilitating the quality control of heated cigarette products.

Visualize data: visualize the collected data and study the relationship between variables; S4. Establishing a method model: drawing a scatter plot of color value and moisture content, selecting and using a suitable mathematical regression model to obtain a linear regression equation, and then obtaining a method model based on the linear regression equation; S5. Use the method model for accurate measurement: After the method model is established, the final moisture indicator colorimetric card is made based on the correspondence between moisture content and color.

[0007] Preferably, the number of heated cigarette tobacco samples in step S2 is no less than 30.

[0008] Preferably, the specific steps of the gas chromatography method used in step S2 include: (1) preparing an internal standard solution; (2) preparing a standard working solution; (3) smoking a heat-not-burn cigarette and collecting total particulate matter with a Cambridge filter; (4) extracting the total particulate matter; (5) gas chromatography determination; and (6) calculating the determination results using a double internal standard method.

[0009] Preferably, in step S3, a scatter plot, data analysis software or other mathematical statistical analysis methods are used to visualize the collected data.
