Description

Technical Field

[0001] The present invention relates to the technical field of tobacco processing, and particularly relates to a method for improving the combustibility and uneven burning of cigar tobacco leaf raw materials. Background Art

[0002] The combustibility of cigar tobacco leaves refers to the performance of generating smoke during smoldering in a free state after the tobacco leaves are ignited. Since the combustibility of cigar tobacco leaves directly affects the sensory quality of cigar tobacco products, it is the most important physical property of cigar tobacco leaves and an important quality index of cigar tobacco products. There are many factors affecting the combustibility of tobacco leaves, but experiments have shown that the potassium ion content in tobacco leaves is positively correlated with combustibility, and the chloride ion content is negatively correlated with combustibility. Only when the potassium-chlorine ratio is within a suitable range, the quality and combustibility of tobacco leaves are the best.

[0003] The raw materials of domestic cigar tobacco leaves are mainly sun-cured tobacco leaves. Due to non-standard agricultural operations during the tobacco leaf planting process, the cigar tobacco leaves are relatively thick, the chloride ion content in the tobacco leaf raw materials is relatively high, the wax layer on the surface of the tobacco leaves is thick and unevenly distributed, and there are problems of poor combustibility and uneven burning during the smoking process of cigar tobacco products. The existing methods mainly improve the combustibility of cigar tobacco leaves by improving the agricultural operation process. Due to the influence of various factors such as environment, climate, and soil, the quality of this method is unstable and the effect is difficult to guarantee. Summary of the Invention

[0004] The purpose of the present invention is to provide a method for improving the combustibility and uneven burning of cigar tobacco leaf raw materials in order to solve the above problems. The present invention can significantly increase the potassium-chlorine ratio and improve the combustibility and uniformity of cigar tobacco raw materials by soaking cigar tobacco leaves in tea liquid and then fermenting.

[0005] The present invention achieves the above purpose through the following technical solutions:

[0010] Step 4: Evenly spray the potassium citrate solution on the processed cigar tobacco leaf raw materials in Step 3, and then carry out industrial fermentation and aging treatment; or directly carry out industrial fermentation and aging treatment on the processed cigar tobacco leaf raw materials in Step 3;

[0011] The fermentation method is as follows: Transfer the tobacco leaves to an oak barrel, cover the barrel lid, and then place the oak barrel in a fermentation chamber to start fermentation. The room temperature of the fermentation chamber is set to: (30 - 50) ± 5 °C, the humidity of the fermentation chamber is set to: (70 - 90) ± 5 °C, and the fermentation time is 3 - 6 days;

[0012] Step 5: Adjust the moisture content of the fermented and aged cigar tobacco leaves to 10 - 20%.

[0035] (5) Compare the chemical components of the tobacco leaves processed by this method.

[0036] Table 2 The following table shows the conventional analytical chemical detection data of the tobacco leaf samples

[0037] Sample Reducing sugar % Total alkaloids % Chlorine % Potassium % Total sugar % Total nitrogen % Sichuan eggplant wrapper (before treatment) 0.14 2.20 4.55 4.20 0.48 3.18 Sichuan eggplant wrapper (Method 1) 0.13 2.14 3.65 3.82 0.48 3.06 Sichuan eggplant wrapper (Method 2) 0.11 2.21 3.63 4.31 0.35 3.04

[0038] 1. In the embodiments of the present invention, for the domestic cigar tobacco leaves with poor combustibility, samples are taken before and after treatment respectively for conventional chemical component detection. The tobacco leaf raw materials from Hainan and Sichuan before treatment are used as the control. The standard methods of "Determination of Water-soluble Sugars in Tobacco and Tobacco Products" (YC / T 159-2002), "Determination of Total Nitrogen in Tobacco and Tobacco Products" (YC / T 161-2002), "Determination of Chlorine in Tobacco and Tobacco Products" (YC / T 162-2011), "Determination of Potassium in Tobacco and Tobacco Products" (YC / T 217-2007) and "Determination of Total Alkaloids in Tobacco and Tobacco Products by Continuous Flow Method" (YC / T 160-2002) are adopted. The detection instrument is an ALLIANCE continuous flow analyzer, and the results are shown in Table 3.

[0039] Table 3 The conventional analytical chemical detection data of the tobacco leaf samples

[0040] Sample Reducing sugar % Total alkaloids % Chlorine % Potassium % Total sugar % Total nitrogen % Potassium-chlorine ratio Hainan eggplant core (before treatment) 0.25 4.02 3.25 6.32 0.4 3.04 1.94 Hainan eggplant core (Method 1) 0.29 3.62 2.25 5.82 0.41 2.76 2.59 Hainan eggplant core (Method 2) 0.31 3.54 2.23 6.45 0.26 2.71 2.89 Sichuan eggplant wrapper (before treatment) 0.14 2.2 4.55 4.2 0.48 3.18 0.92 Sichuan eggplant wrapper (Method 1) 0.2 1.92 3.55 4.15 0.46 2.95 1.17 Sichuan eggplant wrapper (Method 2) 0.19 1.87 3.51 4.37 0.32 2.88 1.25

[0041] It can be seen from Table 3 that the potassium-chlorine ratio of the cigar tobacco leaf raw materials processed by Method 1 and Method 2 increases significantly compared with the control group, while the total sugar content of the tobacco leaves decreases significantly after being processed by Method 2.

[0042] 2. The appearance quality evaluation method mainly evaluates several key influencing factors such as its identity, oil content, uniformity, tissue structure, and single leaf weight. The specific results are shown in Table 4 below:

[0043] Table 4 Appearance Quality Evaluation Results of Tobacco Leaf Samples

[0044] Sample Identity Oil content Uniformity Tissue structure Single leaf weight (g) Hainan eggplant core (before treatment) Thickness Slightly poor Less uniform Tight 8.13 Hainan eggplant core (Method 1) Medium Relatively sufficient Slightly uniform Slightly tight 8.05 Hainan eggplant core (Method 2) Medium - slightly thin Relatively sufficient Slightly uniform Slightly tight 8.01 Sichuan eggplant wrapper (before treatment) Medium Relatively sufficient Less uniform Slightly tight 6.15 Sichuan eggplant wrapper (Method 1) Medium - slightly thin Relatively sufficient Slightly uniform Loose 6.02 Sichuan eggplant wrapper (Method 2) Medium - slightly thin Relatively sufficient Slightly uniform Loose 5.97

[0045] It can be seen from the appearance quality evaluation results that the processed cigar wrapper tobacco leaf raw materials have obvious improvements in identity thickness, oil content and color uniformity, all of which are better than those before processing. The color uniformity of the filler leaf raw materials is better than that before processing.

[0046] 3. The sensory results are shown in Table 5 below

[0047] Table 5 Sensory Quality Evaluation Results of Tobacco Leaf Samples

[0048]

[0049]

[0050] From the sensory quality evaluation results, among all tobacco leaf samples, the domestic cigar tobacco leaf raw materials processed by the present invention have obvious improvements in combustibility, ash color, and coagulation degree. The potassium-chlorine ratio is an important index to measure the combustibility of tobacco leaves. Research shows that potassium ions can improve the combustibility of tobacco leaves, while chlorine ions have a flame-retardant effect. Generally speaking, the higher the potassium-chlorine ratio, the better the combustibility of tobacco leaves. In the present invention, compared with the control group, both Treatment Method 1 and Treatment Method 2 significantly increased the potassium-chlorine ratio. Treatment Method 1 significantly reduced the chlorine ion content, which may be due to the loss of substances in the tea leaves after binding with chlorine ions in the boiled tobacco leaves. In Treatment Method 2, by adding potassium citrate solution, the potassium ion content of the tobacco leaves was significantly increased, so its potassium-chlorine ratio is higher than that of Treatment Method 1, which is consistent with the sensory evaluation results. The combustion characteristics of Treatment Method 2 are slightly higher than those of Treatment Method 1. In addition, the total sugar content after being treated by Treatment Method 2 is significantly lower than that before treatment and that of Treatment Method 1. Research shows that the total sugar content is directly proportional to the ignition point of tobacco leaves. Adding potassium citrate in Treatment Method 2 reduced its total sugar content, which may lower its ignition point and is beneficial to its better combustion characteristics. Finally, after being treated by Treatment Method 1 and Treatment Method 2, there are slight improvements in aroma characteristics, smoke characteristics, and aftertaste characteristics.

[0051] The method of the present invention can better solve the problems of poor combustibility, short smoldering duration, and heavy foreign odor of some domestic cigar tobacco leaves, and can effectively improve the combustibility and uniformity of cigar raw materials to a certain extent.

[0052] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims. Additionally, it should be noted that, for the various specific technical features described in the above specific implementation manner, they can be combined in any appropriate way without contradiction. To avoid unnecessary repetition, the present invention will not separately describe various possible combination manners.
