Embodiment Construction

[0035] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0036] The present invention proposes an embodiment of a method for judging the degree of browning of aged tobacco leaves, specifically, as figure 1 As shown, the following steps may be included:

[0037] Step S1, pre-determining several browning levels based on the apparent color of the aged tobacco leaves, and each browning level corresponds to its respective browning degree range.

[0038] For example, 100 tobacco samples of a certain grade and a certain size with different degrees of browning can be extracted from the tob...

Abstract

The invention discloses a method for discriminating the browning degree of aged tobacco leaves, which is characterized in that a mechanism for discriminating the browning degree of the tobacco leaves is established on the basis of apparent colors, specifically, the grade of the browning degree is preset, and the aged tobacco leaf samples are used for carrying out measurement statistics and comparative analysis on color related indexes, therefore, relatively stable target index data with relatively small mutual influence is obtained, abstract models corresponding to browning degree grades are constructed by using the target index data, and finally, the quantitative browning degree of the tobacco leaves to be detected represented by color values or browning area ratios can be judged in combination with the target indexes of the tobacco leaves to be detected and the abstract models. Compared with sensory analysis, the method has the advantage that the browning degree of the aged tobacco leaves can be quantitatively judged more visually, quickly and accurately.

Description

technical field [0001] The invention relates to the field of tobacco processing, in particular to a method for judging the browning degree of aged tobacco leaves. Background technique [0002] During the aging process, the color of tobacco leaves gradually deepens due to excessive alcoholization, and even turns black. The process is called tobacco leaf browning or tobacco leaf carbonization or tobacco leaf browning. It is closely related to the content changes of phenolic substances, carbohydrates, proteins, amino acids and other nitrogen-containing compounds in tobacco leaf tissue, and the tobacco leaf's own moisture, ambient temperature and humidity, oxygen and other conditions during the storage of tobacco leaves will affect the formation of tobacco leaf browning . If the degree of browning is too deep, the quality of tobacco leaf raw materials will be reduced and even the use value will be lost, so that the enterprise will suffer huge economic losses. [0003] At prese...
