Description

Technical Field

[0001] The invention belongs to the technical field of tobacco processing, and specifically relates to a tobacco blending agent and a method and application of tobacco flavor enhancement and quality improvement. Background Art

[0002] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention, and should not necessarily be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0003] Tobacco raw materials are the foundation for the sustained, stable and healthy development of cigarette brands. Building a well-structured tobacco raw material inventory that is coordinated with the growth of corporate brands is the key to maintaining the stable growth of economic benefits of cigarette industrial enterprises. However, due to the problems of low quality and texture, high irritation, heavy impurities and multiple types, poor combustion and ash holding capacity, unbalanced chemical composition, and poor compatibility with other flavor tobacco leaves, some tobacco leaves are limited in use in Class I and Class II cigarettes and have a long consumption cycle.

[0004] The study found that the current research on improving the quality and style of tobacco leaves and improving their use value mainly focuses on enzyme preparation technology, microbial technology, and process technology. For example, after Du Hongyi and others treated tobacco leaves with enzymes, the tobacco leaf module had obvious effects in reducing irritation, removing impurities, improving taste, and improving purity. Ma Lin and others treated tobacco leaves with external enzymes, and the aroma of the treated tobacco leaves increased, the irritation was significantly reduced, the aftertaste was clean, and the impurities were slight. Hao Jie and others used microorganisms to ferment tobacco leaves, which can effectively adjust and improve the proportion of chemical components inside tobacco leaves and increase the aroma substances in tobacco leaves. Yang Chunqiang and others found that the drying processing caused a decrease in green gas, and except for some low-intensity drying, it caused an increase in burnt aroma and a decrease in fruity aroma. Although the above methods can improve the quality of tobacco leaves to a certain extent, they also have certain limitations, especially some tobacco leaves have heavy impurities and many types, poor combustibility and ash holding capacity, imbalanced chemical composition, and poor compatibility with other flavor tobacco leaves. These problems have not been fundamentally solved. Therefore, a new processing idea is urgently needed to overcome the above problems, so as to enhance the use value of tobacco leaves and improve the quality and compatibility of tobacco leaves. Summary of the invention

[0005] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a tobacco blending agent and a method and application for enhancing the flavor and quality of tobacco.

[0006] In order to achieve the above-mentioned object, the first aspect of the present invention provides a tobacco blending agent, comprising: invert sugar, glycerin, propylene glycol, wolfberry extract, glycyrrhizic acid, monk fruit extract and tomato extract.

[0007] In some embodiments, the tobacco leaf blending agent includes the following components in parts by weight: 25-65 parts of invert sugar, 10-20 parts of glycerin, 6-10 parts of propylene glycol, 2-5 parts of wolfberry extract, 0.1-0.3 parts of glycyrrhizic acid, 0.2-0.4 parts of monk fruit extract and 1-3 parts of tomato extract.

[0008] In some embodiments, the invert sugar is 75% invert sugar syrup.

[0009] Another aspect of the present invention provides a method for enhancing the flavor and quality of tobacco leaves, comprising spraying a tobacco leaf blending agent uniformly on the tobacco leaves, storing the tobacco leaves, and then baking the tobacco leaves at 110-130°C, 105-125°C, and 100-120°C in sequence.

[0010] In some embodiments, the tobacco leaves are baked at 110-130° C., 105-125° C., or 100-120° C. for 15-30 minutes, respectively.

[0011] In some embodiments, the tobacco leaf conditioner is mixed with water to obtain an aqueous solution of the conditioner, which is then evenly applied to the tobacco leaves.

[0012] In some embodiments, when the tobacco blending agent is mixed with water, the mass ratio of invert sugar to water is 1:(3-10).

[0013] In some embodiments, the tobacco leaves are cured at 120°C, 115°C, and 110°C in sequence.

[0014] In some embodiments, the tobacco leaves sprayed with the blending agent are stored in a cabinet for 1.5-3 hours and then subjected to a baking treatment.

[0015] In some embodiments, the mass ratio of invert sugar to tobacco leaves is (2.5-6.5):100.

[0016] In some embodiments, the mass ratio of invert sugar to tobacco leaves is (4-5):100.

[0017] A third aspect of the present invention provides an application of a tobacco blending agent in tobacco leaves.

[0018] The beneficial effects of the present invention are:

[0019] 1. The blending agent of the present invention is prepared by combining invert sugar with a plant extract, which is used before tobacco leaves are baked to improve the quality of tobacco leaves. The blending agent reacts with components in the tobacco leaves to improve the chemical coordination of the tobacco leaves, enhance the aroma quality, improve the aftertaste of cigarettes, and reduce foreign gases. The sensory quality of tobacco leaves is improved, thereby enhancing the smoking quality of cigarettes.

[0045] Comparative Example 1

[0046] This comparative example provides a method for processing tobacco leaves, and the specific steps are as follows:

[0047] The same amount of water as in Example 1 was evenly sprayed on 10 kg of tobacco leaves and stored in a medium cabinet for 2 hours;

[0048] The tobacco leaves stored in the middle cabinet were baked at 120°C (drying zone I), 115°C (drying zone II), and 110°C (drying zone III) for 20 minutes in turn.

[0049] Comparative Example 2

[0050] This embodiment provides a method for processing tobacco leaves, which is different from embodiment 4 in that

[0051] Prepare an aqueous solution of a blending agent: by mass, evenly mix 15 parts of glycerin, 8 parts of propylene glycol, 3.5 parts of wolfberry extract, 0.2 parts of glycyrrhizic acid, 0.3 parts of monk fruit extract, 2 parts of tomato extract and 0.1 parts of water to obtain a tobacco blending agent. Mix 3.35 kg of the above blending agent with 2.7 kg of water.

[0052] Comparative Example 3

[0053] This embodiment provides a method for processing tobacco leaves, which is different from embodiment 4 in that

[0054] Prepare an aqueous solution of a blending agent: by mass, evenly mix 45 parts of invert sugar, 12 parts of glycerin, 8 parts of propylene glycol, 3.5 parts of loquat extract, 0.1 parts of ophiopogon extract, 0.6 parts of acai berry extract, and 0.3 parts of desert fruit extract to obtain a tobacco blending agent, and mix 3.35 kg of the above blending agent with 2.7 kg of water.

[0055] Test example

[0056] The cured tobacco leaves are processed into leaf shreds through subsequent processes, dried at 40°C, ground and passed through a 60-mesh sieve for storage for the determination of chemical composition and aroma components; the other half of the leaf shreds are taken to be rolled into cigarettes for sensory quality evaluation.

[0057] 1. The chemical composition of tobacco leaves obtained in the above-mentioned comparative examples 1-3 and examples 4-6 was determined by continuous flow analysis, and conventional chemical composition indicators such as total sugar, reducing sugar, total alkaloids, total nitrogen, potassium and chlorine of tobacco leaf samples were determined.

[0058] Table 1 Comparative Example, Example 4-Example 6 Chemical Component Content (%)

[0059]

[0060] As can be seen from Table 1, compared with the comparative example, the total sugar and reducing sugar contents of the tobacco leaves of Examples 4-6 increased, and the total nitrogen contents decreased, which to a certain extent indicated that the protein in the tobacco leaves was degraded or converted. Combined with the differences in the changes in the total sugar and reducing sugar contents when treated with different amounts of the conditioning agent, it is speculated that the main reason for the difference may be that: the invert sugar contained in the conditioning agent is relatively high. After the conditioning agent is applied, the total sugar and reducing sugar contents in the tobacco leaves are increased, and the Maillard reaction between the amino acids produced after the degradation of the protein in the nitrogen-containing compounds and the sugars is further promoted, resulting in different contents of total sugar, reducing sugar and total nitrogen under different treatments.

[0061] 2. Comparative Examples 1-3 and Examples 4-6 used simultaneous distillation extraction to extract the aroma components of tobacco leaves, and GC / MS was used to analyze the aroma components of tobacco leaves.

[0062] Table 2 Comparative Examples, Examples 4-6 Aroma substances content (μg / g)

[0063]

[0064]

[0065] It can be seen from Table 2 that, compared with the control example, after the blending agent is applied in Examples 4-6, the total amount of tobacco aroma substances increases, but the content of various aroma components increases and decreases, indicating that the blending agent is involved in the regulation process of tobacco aroma substances.

[0066] 3. For sensory quality evaluation of Comparative Examples 1-3 and Examples 4-6, the four cigarette samples were placed in an environment with a temperature of (22±1)°C and a relative humidity of (60±3)% for at least 48 hours to balance moisture, and then evaluated by a smoking evaluation team consisting of 9 judges from the Shandong Zhongyan Smoking Evaluation Committee. The single-cigarette scoring method was used to evaluate the five aspects of aroma quality, aroma quantity, miscellaneous odor, irritation and aftertaste, with each item scored on a 9-point scale.

[0067] Table 3 Comparative Examples, Examples 4-6 Sensory Quality Evaluation Results

[0068]

[0069] As can be seen from Table 3, compared with the comparative example, the sensory quality of tobacco leaves after baking treatment with the blending agent in Examples 4-6 is improved, and the total scores of the sensory evaluation are from small to large: comparative example < example 6 < example 4 < example 5. All indicators of Examples 4-6 are better than those of the comparative example. It can be seen that the blending agent treatment can affect the quality of tobacco leaves, improve the actual sensory quality difference of tobacco leaves, have good aroma quality, sufficient aroma quantity, reduced irritation, comfortable aftertaste, and obvious sensory quality differences. This may be because the content of aroma substances is increased, and the aroma quality and aroma quantity of tobacco leaves are improved, which shows that the application of blending agents can effectively improve the aroma quality of tobacco leaves and achieve the purpose of enhancing aroma and improving quality.
