Embodiment 1

[0033] Example 1: Based on the mechanism model, the release rule of monomer flavor 3-methylvaleric acid in central heating mode cigarettes was evaluated.

[0034] Step A, sample pretreatment: put the cigarette sample in a constant temperature and humidity chamber with a temperature of (22±1)°C and a relative humidity of (60±2)% for 4 hours, and smoke it in a Canadian depth (HCI) with a linear smoking machine. Cigarette smoking is carried out under the puffing mode, and the cigarette smoking adopts the puff-by-puff method, that is, the first channel captures the first puff of 8 cigarettes, and the second channel captures the second puff of 8 cigarettes. And so on until the end of the 7th puff; the particulate matter in the mainstream smoke of the cigarette is collected with the Cambridge filter, and the gaseous matter in the mainstream smoke of the cigarette is collected with the extract.

[0035] The establishment of the internal standard method standard curve: the steps are t...

Embodiment 2

[0057] Example 2: The release pattern of the monomer flavor 3-methylvaleric acid in cigarettes under the circumferential heating mode.

[0058] With embodiment 1. The difference is that the heating mode of the heated cigarette is a circumferential heating mode, and the heating temperatures are 200°C, 220°C, 230°C, 250°C, and 280°C. In the circumferential heating mode, zero-order kinetic model fitting, pseudo-first-order kinetic model fitting, and pseudo-second-order kinetic model fitting were performed on the cumulative release of monomeric fragrance 3-methylvaleric acid, fitting The result is as Figure 5 The fitting parameters are shown in Table 4.

[0059] The relevant parameters of the pseudo first-order kinetic model of table 4 monomer fragrance 3-methylvaleric acid

[0060]

[0061] According to Table 4, it can be seen that the fitting effect of the release kinetics and the zero-order kinetic model of monomer fragrance 3-methylvaleric acid in different temperature ...

Abstract

The invention discloses a method for evaluating a release rule of a single spice in cigarettes based on a mechanism model. The method comprises the following steps: (1) measuring puff-by-puff release amount; (2) calculating an accumulated release amount; (3) performing dynamic fitting to obtain a dynamic rate constant; (4) carrying out Arrhenius equation fitting to obtain activation energy and pre-exponential factors; (5) drawing a thermogravimetric analysis first-order differential curve graph through a thermogravimetric experiment to obtain a peak temperature, and calculating enthalpy change and Gibbs free energy change; and (6) evaluating the release rule of the monomer perfume in the cigarette according to the dynamic fitting result, the activation energy, the enthalpy change and the Gibbs free energy change. According to the method disclosed by the invention, a relatively objective, real and comprehensive monomer perfume release rule is obtained. According to the evaluation method provided by the invention, the monomer flavors can be selected in a targeted manner, and comprehensive data and guidance are provided for the formula design of the cigarette monomer flavors of cigarette products.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to a method for evaluating the release law of monomeric spices in cigarettes based on a mechanism model. Background technique [0002] Due to the high temperature of traditional cigarettes during combustion, the cracking of tobacco produces and releases a large amount of harmful substances, which is harmful to the human body. Heat-not-burn cigarettes have the advantages of low heating temperature, non-combustion, low release of harmful substances, and can meet the taste requirements of smokers when smoking cigarettes, etc., and have become a research hotspot in recent years. In order to meet the different tastes of smokers, various characteristic flavoring materials are generally added to heat-not-burn cigarettes. For emerging heat-not-burn cigarettes, it is particularly important to explore the migration and release of characteristic flavoring materials during the heat...
