Embodiment 1

[0035] The tobacco aroma raw material selected in this example is citric acid.

[0036] Tobacco incense raw materials, water, and propylene glycol were analyzed and detected by thermogravimetric analysis according to the following conditions: sample amount: 10-80 mg; purge gas: N 2 Or compressed air; purge gas flow: 90mL / min; equilibrium gas flow: 10mL / min; heating program: 10°C / min speed, from room temperature (25-30°C) to 400°C.

[0037] The thermogravimetric curve analysis diagram is as follows figure 1 shown.

[0038] It can be clearly seen from the figure that the weight change curve of the tobacco incense raw material is located on the right side of propylene glycol, indicating that the tobacco incense raw material has better thermal stability at higher temperatures, and the tobacco incense raw material is suitable for cigarettes Feeding link in the production process.

Embodiment 2

[0040] The tobacco incense raw material selected in this embodiment is ethyl propionate.

[0041] Tobacco incense raw materials, water, and propylene glycol were analyzed and detected by thermogravimetric analysis according to the following conditions: sample amount: 10-80 mg; purge gas: N 2 Or compressed air; purge gas flow: 90mL / min; equilibrium gas flow: 10mL / min; heating program: 10°C / min speed, from room temperature (25-30°C) to 200°C.

[0042] The thermogravimetric curve analysis diagram is as follows figure 2 shown.

[0043] It can be clearly seen from the figure that the weight change curve of the tobacco incense raw material is located on the left side of the ethanol, indicating that the thermal stability of the tobacco incense raw material is poor, and the tobacco incense raw material is suitable for addition in the cigarette production process. Fragrance link.

Embodiment 3

[0045] The tobacco incense raw material selected in this example is Peruvian extract, which is denoted as incense raw material 3.

[0046] Tobacco incense raw materials, water, and propylene glycol were analyzed and detected by thermogravimetric analysis according to the following conditions: sample amount: 10-80 mg; purge gas: N 2 Or compressed air; purge gas flow: 90mL / min; equilibrium gas flow: 10mL / min; heating program: 10°C / min speed, from room temperature (25-30°C) to 400°C.

[0047] The thermogravimetric curve analysis diagram is as follows image 3 shown.

[0048] It can be clearly seen from the figure that the weight change curve of the tobacco incense raw material is between water and propylene glycol. It is further judged that the weight loss rate of the tobacco incense raw material at 150°C reaches 85wt%, which indicates that the tobacco incense raw material has a The thermal stability is poor. According to the evaluation method of the present invention, the weig...

Abstract

The invention provides a rapid evaluation method for the applicability of a tobacco flavor raw material in a cigarette production process. In the present invention, by performing thermogravimetric analysis on the tobacco flavor raw material sample, the first reference product, and the second reference product under the same conditions, the weight change curve of the tobacco flavor raw material sample obtained by the thermogravimetric analysis and the first reference product are further compared. The positional relationship between the weight change curve and the weight change curve of the second reference product can quickly, accurately and scientifically determine the additive process applicable to the production process of tobacco flavor raw materials, which has guiding significance for the use of new tobacco flavor raw materials , can better exert the flavor-increasing effect of the flavoring raw materials for tobacco, and is more conducive to the preparation of cigarettes with new flavors by using different flavoring raw materials for tobacco.

Description

technical field [0001] The invention belongs to the technical field of tobacco flavor and fragrance analysis, and in particular relates to a method for rapidly evaluating the applicability of tobacco flavor raw materials in a cigarette production process. Background technique [0002] In order to impart richer and more distinctive flavors to cigarettes, aroma raw materials are usually added during the production process of cigarettes. The addition of fragrant raw materials can generally be added during the shredding process (the industry is called feeding), or it can be added after the silk is dried (the industry is called adding fragrance). Usually, cigarettes need to go through the process of drying silk (usually the drying temperature is 150-200 ℃) after feeding, and the subsequent process of adding aroma is rolling, and no need to go through heating. Therefore, the selection of aroma raw materials needs to be differentiated. . Single fragrance raw materials can be scre...
