Embodiment Construction
[0026] The present invention finds that the physical characteristics of tobacco leaves (such as thickness, filling value, tension, stalk content, equilibrium moisture content and leaf surface density, etc.) are related to miscellaneous air. The model evaluates the miscellaneous gases in the flue gas quickly, accurately, at low cost and easily.
[0027] A method embodiment of the present invention to evaluate the miscellaneous gas in flue gas, its flow process is as follows figure 1 As shown, the process is as follows:
[0028] Step 1: Collect 796 tobacco leaf samples from different origins, quantitatively detect the indicators such as sample equilibrium moisture content, filling value, thickness, tension, leaf surface density, stem content rate, etc., and obtain the physical characteristic data of these tobacco leaf samples, as shown in Table 1 shown (only part of the data is shown).

The invention belongs to the technical field of tobacco detection, and particularly relates to a method for evaluating miscellaneous gas in smoke. The method comprises the following steps: firstly, acquiring physical characteristic data of tobacco leaves to be evaluated, and converting the physical characteristic data, so that six comprehensive indexes obtained after conversion processing are related to each kind of physical characteristic data before conversion processing, wherein the physical characteristic data comprises the following six types: thickness, filling value, tension, stem content, balanced moisture content and leaf surface density; and inputting the six comprehensive indexes into a constructed miscellaneous gas evaluation model to obtain miscellaneous gas scoring results corresponding to the six comprehensive indexes. According to the method, a miscellaneous gas evaluation result can be obtained without professional smoking evaluation personnel through cigarette sensoryevaluation, the defects of strong professional dependence, long consumed time and the like of a traditional method are overcome, meanwhile, chemical agents are not required to be used for determiningchemical components, samples cannot be damaged, and the method has the advantages of simplicity in operation, reagent saving, short time, low cost, no pollution and the like.
Description
technical field [0001] The invention belongs to the technical field of tobacco detection, and in particular relates to a method for evaluating miscellaneous gases in smoke. Background technique [0002] In recent years, with the diversified needs of the tobacco market and the continuous adjustment of cigarette product formulas, tobacco manufacturers have higher and higher requirements for the quality of raw materials. Tobacco leaf quality is the most important factor affecting the quality of cigarette products, and good cigarette products cannot be separated from good tobacco leaves. [0003] There are some miscellaneous gases in the smoke produced by the burning of tobacco leaves. Miscellaneous gases refer to the unpleasant smell in the smoke, which will lead to the decline of the quality of tobacco leaf products and the change of aroma style characteristics. As one of the important indicators of cigarette sensory evaluation, miscellaneous gas has been widely concerned by ...
