[0005] "Determination of Tobacco Mixing Uniformity" (Standard No. YC/T 426-2012) stipulates a characteristic value constructed using total sugar, total plant alkaloids and potassium in shredded tobacco as an indicator for evaluating tobacco mixing uniformity; but this method The timeliness is poor, and it is only applicable to the conditions with significant difference in characteristic values, and the scope of application is limited; in addition, because it can only measure the degree of mixing uniformity, it is impossible to know the proportion of each component and the component that causes the difference in mixing uniformity, so has limited guiding value for production;
[0006] The patents "A Method for Measuring the Proportion of Shredded Tobacco in Cigarettes" (Application No. CN200610018050.8) and "A Method for Evaluating Mixing Uniformity of Cut Tobacco" (Application No. CN201110339610.0) disclose a method that uses manual separation and density method The method of liquid floating separation detects the proportion of each component of cut tobacco; although this method has high accuracy and reliability, the operation is cumbersome and time-consuming, and it cannot achieve fast and continuous detection, so it is not suitable for online monitoring applications ;
[0007] The patent "A Method for Measuring the Uniformity of Cut Tobacco, Cut Stems, and Reconstituted Tobacco Leaf Formula" (application number CN201710179755.6) discloses a method for evaluating the mixing uniformity of cut tobacco based on the characteristic values ​​of total sugar and cellulose, but the method More chemical compos

Embodiment 1

[0060] Since the preparation of multi-component shredded tobacco samples is relatively complicated, this example only takes two kinds of shredded tobacco components (shredded leaves + shredded stems) as examples, and briefly introduces the method for detecting the blending ratio of each component in shredded tobacco provided by this application as follows .

[0061] (1) Pretreatment of each component sample of shredded tobacco and construction of calibration set samples

[0062] Take an appropriate amount of shredded leaves and shredded stems, spread them on trays, put them in an oven and bake them at 40°C for 4 hours, then put them into sealed bags and store them for later use.

[0063] According to the needs of cigarette products, reasonably set the limit value of the blending ratio of each component (the blending ratio of shredded stems is set between 10% and 40% in this example) and the change gradient (the design of this example uses an equal gradient of 2% ) and prepare...

Embodiment 2

[0105]The method for detecting the blending ratio of shredded tobacco provided in this embodiment is generally the same as that in Embodiment 1, only some operations are adjusted. The details of the adjustments and results are as follows.

[0106] In step (2): select the three characteristic chemical components of total plant alkaloids, total sugars, and chlorine as the principal components, and then use SPSS to conduct principal component analysis (the coefficient matrix for calculating the scores of the principal components based on the contents of the three chemical components is shown in Table 2- 1), and output the factor score (which can be calculated by the comprehensive factor score calculation formula (2)). The specific chemical composition content detection and factor scoring results are shown in the following tables 2-2 to 2-6 (tables 2-2 to 2-6 represent the test results of a group of samples respectively);

[0107] Finally, through regression analysis, a linear re...

Abstract

The invention belongs to the technical field of tobacco processing and detection, and particularly relates to a method for detecting a blending proportion of components in cut tobacco. The method comprises steps of pretreating samples of the components of the cut tobacco, building a calibration set sample, constructing a blending proportion prediction model based on synthetic chemical factor scores, establishing a near-infrared prediction model of synthetic factor scores, performing detection and judgment and the like. According to the method for detecting the blending proportion of the components in the cut tobacco, multiple synthetic chemical factors are taken as chemical characteristic values for characterizing the blending proportion of the cut tobacco, and evaluation requirements forblending uniformity of different types and different categories of the cigarette cut tobacco can be met better. With adoption of the method for detecting the blending proportion of the components in the cut tobacco, not only is the foundation laid for detection and judgment of the components of the cut tobacco, but also the good foundation can be laid for online continuous monitoring and control for blending uniformity of the cut tobacco, and the method has better practical value and popularization and application significance.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing and detection, and in particular relates to a patent application matter for a method for detecting the blending ratio of each component in shredded tobacco. Background technique [0002] The ratio of components such as shredded leaves, shredded stems, expanded shredded tobacco, and shredded tobacco in shredded tobacco is the core composition of cigarette formula, and the quality of cigarettes can be fully reflected by the reasonable blending of each component after the blending and flavoring process. Therefore, if the blending ratio of each component in shredded tobacco is not appropriate or the blending result is not uniform enough, the sensory quality of the cigarette will be unstable, thereby adversely affecting the homogenization and stabilization of the cigarette. [0003] In the prior art, the adjustment of the blending ratio of shredded tobacco is mainly: first set the blending r...
