Embodiment 1

[0028] figure 1 In this method, the quadratic polynomial stepwise regression is used to characterize the compatibility characteristics of tobacco leaves, and the tobacco leaf compatibility information is extracted by the contour method and the contribution rate method, which is used to guide product development and product maintenance. The specific steps are as follows:

[0029] (1) Experimental scheme design: choose a variety of methods for experimental design, such as orthogonal experimental design, factorial experimental design, uniform experimental design, etc. After optimization, choose uniform design as the experimental design method, and design according to the number of factor levels and the number of factors Uniform experimental design table;

[0030] (2) Preparation of mixing test samples: the mixing test was carried out according to the monomers and usage ratios listed in the monomer mixing test design table, and all cigarettes for sensory evaluation in the mixing t...

Embodiment 2

[0067] Model building steps are the same as embodiment 1:

[0068]

[0069] Assuming that the proportions of the monomers used to prepare the module in actual production are monomer X1=30, monomer X2=30, monomer X3=10, monomer X4=20, monomer X5=10, the aroma of the module can be obtained by calculation Temperament: 7.0786.

[0070]

[0071] From the overall contribution rate calculated above, we can roughly see that the monomers X2 and X1 have a greater impact on the aroma of the module, and they can improve the aroma. The effect of monomer X3 on the aroma of the module is to reduce the aroma of the module.

[0072] Here we want to improve the aroma of the module, so the goal should be to increase the amount of monomer X2 and monomer X1, and reduce the amount of monomer X3, but due to the interaction between monomers, blindly reduce the amount of monomer X3, and blindly increase The amount of monomer X2 and monomer X1 is unscientific, and the opposite result may be obt...

Abstract

The invention relates to an evaluation method for the characteristics of tobacco compatibility; the method applies stepwise regression of quadratic polynomial to represent quantitatively the characteristics of tobacco compatibility, extracts the tobacco compatibility information by a contour method and a method of contribution rate, and is used for guiding the research and development and maintenance of products. By describing the tobacco compatibility information, the evaluation method of the invention is beneficial to the maintenance and research and development of products and describing the compatibility characteristics quantitatively.

Description

technical field [0001] The invention relates to a method for evaluating the compatibility characteristics of tobacco leaves. Background technique [0002] The stability of cigarette product quality and the research and development of new cigarette products are the basis for the survival and development of cigarette enterprises, and the mining of tobacco leaf compatibility information is particularly important. [0003] Internationally renowned cigarette manufacturers, such as Philip Morris, British American Tobacco, etc., have established a complete, scientific and reasonable system for the research on the compatibility characteristics of tobacco leaves, and this system has been directly applied to tobacco leaf blending. Description of compounding and substitution rules, and compounding of formula units and leaf group formulas. [0004] Cigarette formulation workers in various cigarette enterprises in my country are very familiar with the characteristics of the cigarette ra...
