[0001] This invention belongs to the field of tobacco processing technology, and specifically relates to a method for improving the quality of tobacco leaves through additives. Background Technology
[0002] Different tobacco-growing regions and the pH of the soil used for tobacco cultivation significantly affect the chemical composition of tobacco leaves. When the soil is slightly acidic to neutral, with low levels of soil organic matter and available nitrogen, but abundant available phosphorus and potassium, and rich in zinc and selenium, the chemical composition of the tobacco leaves is as follows: higher nicotine content, lower total sugar and reducing sugar content, and a lower sugar-to-nicotine ratio; lower chlorine content and a higher potassium-to-chlorine ratio; higher starch content; and the tobacco leaves have a less intense aroma, stronger off-flavors, longer mouthfeel, and poorer palatability.

Detailed Implementation
[0021] The related technologies of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0022] like Figures 1-8As shown, the method for improving tobacco quality in this embodiment selects and blends with tobacco leaves from Ankang, Shaanxi Province. Considering the characteristics of tobacco leaves from different producing areas, the 2019 C3FTY99 tobacco leaves from Shangluo, Shaanxi Province, are used as the target for improvement. Using Ankang tobacco leaves as the main component and Shangluo tobacco leaves as the auxiliary component, four leaf group modules were designed (as listed in Table 1), and sensory evaluation was conducted. The results are shown in Table 2. As can be seen from the table, the overall effect of the combination of the two Shaanxi tobacco leaves is worse than that of the combination with tobacco leaves from other provinces. However, apart from a slight decrease in aroma, the key indicators such as off-flavors and residues show significant improvement after combination, thus demonstrating high combination value. Comparatively, as the proportion of Shangluo tobacco leaves in the leaf group module increased from 5% to 20%, the overall quality of the module experienced two cycles of initial deterioration followed by improvement. This is mainly because the aroma profiles of Ankang and Shangluo tobacco leaves differ to some extent. When the proportion of Shangluo tobacco leaves is low (5%, 10%), the characteristics of the blend modules are predominantly Ankang tobacco leaves; when the proportion of Shangluo tobacco leaves is high (15%, 20%), the blend modules exhibit a certain degree of Shangluo tobacco leaf characteristics. Overall, the effects of Shaanxi tobacco leaf blend modules #2 and #4 are improved to some extent compared to using Ankang tobacco leaves alone. Table 1 shows the blending methods for tobacco leaves from within Shaanxi Province, and Table 2 shows the evaluation results of blend modules combining Shaanxi Ankang tobacco leaves with tobacco leaves from other parts of the province.
[0023]
[0024]
[0025] In the aforementioned study, tobacco leaves from both within and outside Shaanxi Province, along with their blending ratios, were selected based on their good compatibility with Ankang tobacco leaves. Among the leaf blend modules combining three types of tobacco leaves from outside Shaanxi Province with Ankang tobacco leaves, two types of Fujian tobacco leaves (especially Sanming tobacco leaves) had a low proportion, which may lead to uneven blending issues during future production. In contrast, among the leaf blend modules combining tobacco leaves from within Shaanxi Province with Ankang tobacco leaves, Shangluo tobacco leaves had ample inventory and constituted a large proportion of the modules, which is beneficial for production organization. Therefore, subsequent feeding will primarily utilize tobacco leaf modules #2 and #4 from within Shaanxi Province.
[0026] First batch of ingredients formula: Based primarily on licorice powder, J-MRP, 99125-3, sweetener base, and flavor enhancer base, four flavoring formulations (A, B, C, and D) were designed, as shown in Table 3. Table 3 presents the flavoring formulations for Shaanxi tobacco leaves. Table 3 is calculated based on an addition amount per 100g of tobacco leaves; the unit is g.
[0027]
[0028] The above-mentioned additives A, B, C, and D were tested in the addition of Shaanxi Tobacco Leaf No. 2 blend tobacco, and sensory evaluations were conducted. The results are shown in Table 4 and [Table data missing]. Figure 1As shown in the figure, adding ingredients has a significant effect on masking off-flavors and increasing sweetness, but its effect on improving irritation and residue is not obvious.
[0029] Specifically, Material A is the base material among the four, providing the initial liquor for processing Shaanxi tobacco leaves. Due to the lack of other functional modules, its effect is relatively poor. Material B, based on Material A, adds conventional sugar and acid components and increases the amount of licorice powder, resulting in improved masking and sweetening effects. Material C, based on Material B, adds a sweetening base, significantly improving its masking effect and increasing its aftertaste. Material D, based on Material C, adds the browning reaction product J-MRP, resulting in a significant overall improvement, especially in important indicators such as aroma quality, aroma quantity, and residue.
[0030] Second batch of additive formula: Of the four blending solutions in the first batch of additive formulations, solution D was the most effective for Shaanxi tobacco leaf No. 2 blend, but its flavor was slightly stronger, which differed from the current demand for cigarette products. Therefore, the following adjustments were made to solution D: (1) Appropriately reduce the amount of J-MRP.
[0031] (2) Use the browning reaction product Y-BRP to balance the problem of excessive smoke flavor caused by the use of J-MRP in material D, which brings about the fullness and masking of impurities.
[0032] (3) When using J-MRP, the aroma amount can be guaranteed, and flavoring base is no longer used.
[0033] (4) Malt extract is no longer used when J-MRP can effectively mask impurities.
[0034] (5) Only honey and the Ankang tobacco acid material developed in this project are used for the sugar-acid material, and conventional sugar-acid material will no longer be used.
[0035] Based on the above principles, the E-material was redesigned and added to the Shaanxi No. 2 tobacco blend, followed by sensory evaluation. Figure 2 As shown in the graph, compared to material D, material E has a better aroma and a slightly increased sweetness; the improvement in aroma intensity is significantly less, but it does not cause a decrease in the aroma intensity of the tobacco leaves themselves; other indicators are basically the same. What is not reflected in the evaluation indicators is that the tobacco flavor of material E is significantly weaker than that of material D. In summary, material E meets the design objectives.
[0036] Third batch of additive formula: During the blending of Shaanxi No. 2 formula tobacco treated with E-material in the second batch of additive formulations into Hao Mao (Brand A) and Hao Mao (Brand B) finished cigarettes, it was found that adding 5% of the treated Shaanxi No. 2 formula tobacco caused a significant decline in the quality of the two finished cigarettes, especially in terms of aroma, off-flavors, and taste. Therefore, based on the E-material, a JX13 section was added, and F-materials and G-materials were designed.
[0037] Sensory evaluation was conducted on the Shaanxi No. 2 blend tobacco shreds after the addition of F and G additives. The results are shown in Table 5-8. Figure 3 As shown in the figure, the F-grade compound improves the aroma quality, off-flavors, smoothness, sweetness, and residue to a certain extent, with a relatively balanced overall effect. The G-grade compound shows a more significant improvement in aroma quality, aroma quantity, off-flavors, concentration, smoothness, sweetness, and residue. Relatively speaking, the F-grade compound has a certain improvement effect on preserving the light smoke state of Shaanxi tobacco leaves, and on key indicators such as off-flavors and residue. The G-grade compound, while having basically the same improvement indicators as the F-grade compound, has a better effect on enhancing aroma and intensity. In summary, the introduction of the third batch of additive formulas into the JX13 section further improved the sensory effects of the additive treatment. The F-grade and G-grade compounds were determined to be the additive formulas used for treating Shaanxi tobacco leaves. Table 4 shows the sensory effects of the additive formulas in Shaanxi tobacco leaf No. 2 blend tobacco.
[0038]
[0039] Optimization of feeding and drying conditions in laboratory-scale trials: To investigate the effect of added feedstock on drying conditions, the determined feedstock E was sprayed into modules 2 and 4 of Shaanxi tobacco leaves in the laboratory, and drying and sample preparation were carried out according to the two drying temperatures listed in Table 5. Sensory evaluations were conducted on Shaanxi tobacco leaf samples with different drying conditions, and the results are shown in Table 6. Figure 4 Table 5 shows the sample preparation scheme for Shaanxi tobacco leaves with added feed, and Table 6 shows the sensory evaluation results of Shaanxi tobacco leaves with added feed under different drying conditions.
[0040]
[0041]
[0042] As shown in the figure, for Shaanxi tobacco No. 2 module after adding E-material, the overall effect of low-intensity drying (120℃) is better than that of high-intensity drying (130℃). Specifically, as the drying intensity increases, the improvement of indicators such as impurities, smoothness, and residue in Shaanxi tobacco No. 2 module decreases, and it also causes greater irritation.
[0043] Considering that the overall aroma and quality of Shaanxi Tobacco Module 4 is slightly inferior to that of Shaanxi Tobacco Module 2, only a high-intensity drying test was conducted on Shaanxi Tobacco Module 4 after adding additives. Compared with the low-intensity drying of Shaanxi Tobacco Module 2 after adding additive E, the high-intensity drying effect of Shaanxi Tobacco Module 4 after adding additive E is generally similar, with a slightly better improvement in the fineness index.
[0044] After processing, Shaanxi tobacco leaves are blended into the finished tobacco product: In this embodiment, the effects of different additive plates and their combinations in materials A, B, C, and D were investigated. Material E was obtained through optimization, material F was obtained through improvement, and material G was innovatively developed. Considering the effects of each additive liquid on Shaanxi tobacco No. 2 blended tobacco, Shaanxi tobacco No. 2 and No. 4 blended tobacco treated with materials E, F, and G were selected as blended tobaccos. Good Cat (brand A) and Good Cat (brand B) were used as the blending materials for the finished tobacco products, and blending experiments were conducted on Shaanxi tobacco after additive treatment.
[0045] The effect of additive treatment on the blending ratio of Shaanxi tobacco leaves: The effects of different blending ratios of Shaanxi tobacco leaves treated with additive E on the finished cigarettes of Haomao (Brand A) and Haomao (Brand B) were investigated. The results are shown in Table 7. Figure 5 and Figure 6 Table 7 shows the sensory evaluation results of samples of Shaanxi tobacco leaves treated with E material blended into the finished tobacco shreds after drying.
[0046]
[0047] As shown in the figure, when the Shaanxi tobacco leaves treated with E were blended in the same proportion in Haomao (Brand A), the effect of the 4# leaf group module was slightly better than that of the 2# leaf group module; when blended in the same proportion in Haomao (Brand B), the 2# leaf group module was slightly better than the 4# leaf group module.
[0048] In the experiments with blending ratios of 5%, 10%, and 15%, the proportion of Shaanxi tobacco leaves blended with the E-material treatment increased, and the overall quality of both Hao Mao (Brand A) and Hao Mao (Brand B) showed a downward trend. Therefore, the blending ratio of Shaanxi tobacco leaves with the added material treatment in Hao Mao (Brand A) and Hao Mao (Brand B) will be uniformly determined to be 5% external blend.
[0049] Determination of the feeding and processing scheme for high-quality Shaanxi tobacco leaves: Section 6.1 investigated the blending effect of added Shaanxi tobacco leaves in finished cigarettes. It was found that although the quality of Shaanxi tobacco leaves treated with E material was significantly improved, blending them in finished cigarettes still caused a significant decline in the quality of finished cigarettes.
[0050] To further improve the harmony between Shaanxi tobacco leaves and finished cigarettes after additive processing, JX13 was added to the E-material, resulting in the development of the F-material, and a new G-material was also developed. The quality of Shaanxi tobacco leaves treated with these two additives was significantly improved. Therefore, Shaanxi tobacco leaves treated with both F and G-materials were blended at a uniform ratio of 5% into the dried tobacco shreds of Hao Mao (Brand A) and Hao Mao (Brand B) finished cigarettes. The results are shown in Table 8. Figure 7 and Figure 8 Table 8 shows the sensory evaluation results of samples of Shaanxi tobacco leaves with 5% added to the finished tobacco shreds after drying.
[0051]
[0052] Depend on Figure 7 It is evident that both F and G treatments of Shaanxi tobacco leaves with 5% Hao Mao (Brand A) after drying improved the permeability and sweetness of Hao Mao (Brand A). Comparatively, the low-intensity treatment of Shaanxi tobacco leaf No. 2 blend tobacco leaves was less effective than the high-intensity treatment of Shaanxi tobacco leaf No. 4 blend tobacco leaves in terms of both off-flavors and residues. In the G treatment of Shaanxi tobacco leaf No. 4 blend tobacco leaves with 5% Hao Mao (Brand A) after drying, the effect on permeability was minimal, but the concentration and sweetness were significantly improved, although there was a slight negative impact on off-flavors and residues.
[0053] Considering that the main characteristic of Good Cat (Brand A) finished cigarettes is a relaxed and natural smoke state, and under the premise of minimizing the impact on the finished cigarettes, the Shaanxi tobacco leaf formula used for blending was determined to be No. 4, the added material was F, and the drying intensity was high-strength drying.
[0054] Depend on Figure 8 It is evident that both F and G materials, when used to treat Shaanxi tobacco leaves with 5% blended with Hao Mao (Brand B) after drying, improved the smoothness, mellowness, and sweetness of Hao Mao (Brand B). Comparatively, the low-intensity F material treatment of Shaanxi tobacco leaf Formula 2# resulted in slightly better results in terms of impurities compared to the high-intensity F material treatment of Shaanxi tobacco leaf Formula 4#. Overall, the G material treatment of Shaanxi tobacco leaf Formula 4# with 5% blended with Hao Mao (Brand B) after drying resulted in better results than the F material treatment, specifically in terms of improved smoothness and mellowness as well as improved residue.
[0055] The comparison shows that, for Good Cat (Brand B) finished cigarettes, the high-strength drying of Shaanxi tobacco leaf No. 4 formula shreds treated with G material is the better solution.
[0056] Regarding the quality improvement of tobacco blends from other provinces: To compare the sensory quality of blends of tobacco leaves from other provinces with those from Ankang, Shaanxi, this implementation method conducted a 1:1 pairwise evaluation of Ankang tobacco leaves and major tobacco leaves from Shaanxi Tobacco's inventory (Zimbabwe, Yunnan, Hunan, and Fujian). The results showed that the sensory quality of blends of Zimbabwean and Yunnan tobacco leaves with Ankang tobacco leaves was significantly worse than that of Zimbabwean and Yunnan tobacco leaves alone, and therefore did not demonstrate any value in improving Ankang tobacco quality through blending. The sensory quality of blends of Hunan and Fujian tobacco leaves with Ankang tobacco leaves was slightly worse than that of Hunan and Fujian tobacco leaves alone, but significantly better than that of Ankang tobacco leaves, warranting further research.
[0057] While ensuring that Ankang tobacco leaves constitute the majority, the impact of the blending ratio of Ankang tobacco leaves with Hunan and Fujian tobacco leaves was further investigated. It was basically determined that blending approximately 10% Hunan and Fujian tobacco leaves can help improve the quality of Ankang tobacco leaves. Therefore, a combination module with Ankang tobacco leaves as the main component and a certain amount of Hunan and Fujian tobacco leaves as the secondary component was designed, as shown in Table 9.
[0058]
[0059] The sensory evaluation results of the blended tobacco leaves from Ankang, Shaanxi Province, and other provinces are shown in Table 10. As can be seen from the table, Module 1# has a significant effect on masking off-flavors and has a certain effect on improving taste indicators such as irritation and residue; Module 2# has a certain effect on masking off-flavors and reducing irritation, but the residue worsens; Module 3# has a significant effect on improving aroma, masking off-flavors, increasing sweetness, and improving aftertaste; Module 4# has a slightly improved aroma and significantly masked off-flavors, but the improvement in residue and permeability is only moderate.
[0060] Overall, the No. 3 leaf group module, which combines tobacco leaves from Ankang, Shaanxi with tobacco leaves from other provinces, performed relatively well, showing a significant improvement in masking off-odors and reducing residues compared to using Ankang tobacco leaves alone.
[0061]
[0062] Regarding quality improvement through blending with tobacco leaves from within the province: When screening and studying tobacco leaves from within Shaanxi Province that were blended with those from Ankang, Shaanxi, Shaanxi, the Shaanxi Tobacco inventory and the characteristics of tobacco leaves from the producing areas were taken into consideration, and the 2019 C3FTY99 tobacco leaves from Shangluo, Shaanxi were selected as the research object.
[0063] Using Ankang tobacco as the main component and Shangluo tobacco as a supplement, four leaf group modules were designed (see Table 1 for details), and sensory evaluation was conducted, with results shown in Table 2. As can be seen from the table, the overall effect of the combination of the two Shaanxi tobacco leaves was worse than that of the combination with tobacco leaves from other provinces. However, apart from a slight decrease in aroma, the key indicators such as off-flavors and residues showed significant improvement after combination, thus demonstrating high combination value. Comparatively, as the proportion of Shangluo tobacco in the leaf group modules increased from 5% to 20%, the overall quality of the modules experienced two cycles of initial deterioration followed by improvement. This is mainly because Ankang and Shangluo tobacco have certain differences in aroma profile. When the proportion of Shangluo tobacco was low (5%, 10%), the characteristics of the combined modules were mainly those of Ankang tobacco; when the proportion of Shangluo tobacco was high (15%, 20%), the combined modules exhibited a certain degree of Shangluo tobacco characteristics. Overall, the combined modules of Shaanxi tobacco #2 and #4 showed a certain degree of improvement compared to using Ankang tobacco alone.
[0064] In this embodiment, tobacco leaves from both within and outside Shaanxi Province with good compatibility with Ankang tobacco leaves were selected, along with their combination ratios. Among the leaf blend modules combining three types of tobacco leaves from outside Shaanxi Province with Ankang tobacco leaves, two types of Fujian tobacco leaves (especially Sanming tobacco leaves) accounted for a relatively low proportion, which may lead to uneven blending issues during future production. In contrast, among the leaf blend modules combining tobacco leaves from within Shaanxi Province with Ankang tobacco leaves, Shangluo tobacco leaves had ample inventory and constituted a large proportion of the modules, which was beneficial for production organization. Therefore, subsequent research on the addition of these leaves will primarily focus on tobacco leaf modules #2 and #4, which are combinations from within Shaanxi Province.
[0065] In summary, this invention provides a systematic and effective method for improving the quality of tobacco leaves through additive processing. By studying the compatibility of Ankang tobacco leaves from Shaanxi Province with Shangluo tobacco leaves from within the province, a suitable combination ratio was determined. Multiple batches of additive formulations were designed and screened, continuously optimizing the additive effect. Laboratory-scale optimization of the additive drying conditions was conducted, clarifying the appropriate drying intensity for different modules. Regarding the blending of finished cigarettes, through experiments with different blending ratios and additive treatment schemes, the optimal Shaanxi tobacco leaf formulation, additive varieties, and drying intensity were determined for both Haomao (Brand A) and Haomao (Brand B). This method not only improves the quality of Shaanxi tobacco leaves but also enhances their harmony with finished cigarettes, providing important technical support and practical reference for tobacco processing and cigarette production, and contributing to improving the overall quality and market competitiveness of cigarette products.
[0066] It should be emphasized that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
