Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tobacco additives, in particular to a method for regulating the smoke concentration of tobacco leaves and a regulating agent thereof. BACKGROUND

[0002] With the vigorous development of domestic cigarette enterprises, people have higher requirements for the diversification of tobacco raw materials. From the three tobacco flavors of thick, medium and light proposed in the last century to the eight flavors developed in recent years, the national flue-cured tobacco leaf style zoning system has been restructured. Sensory evaluation is an important method for evaluating tobacco quality, and the quality of sensory quality directly determines the quality of tobacco quality. Among them, the smoke concentration represents the state when the smoke fills the mouth, the more the aroma substances, the greater the aroma amount, and the higher the smoke concentration. Therefore, improving the smoke concentration of tobacco leaves has a positive significance for changing the style characteristics of tobacco leaves and the development of cigarettes.

[0003] In order to improve the smoke concentration of tobacco leaves, technical personnel in the industry use various tobacco additives to prepare tobacco leaves. For example, the patent with publication number CN114698870B discloses a method for improving the smoke concentration of tobacco leaves by fermenting tobacco leaves with guarana extract. The guarana extract is mixed with a solvent in a certain proportion to obtain a mixed solution for fermentation. Different varieties of cigar tobacco leaves from different production areas are prepared, and the mixed solution is uniformly sprayed on the surface of the cigar tobacco leaves. Then the cigar tobacco leaves are packed in a linen bag and placed in a constant temperature and humidity incubator. The fermentation humidity is set to 65-75%, the temperature is set to 30-40℃, and the fermentation period is 30-40d. After fermentation, the fermented tobacco leaves are taken out for moisture balance. However, the above method takes a long time and is only suitable for cigar tobacco leaves, and is not suitable for tobacco leaves using the baking process.

[0004] For example, the patent with publication number CN105831793B discloses a papermaking method for adjusting the smoke concentration of reconstituted tobacco leaves and its use method, which includes the following components: Chinese medicine tincture 18-35%, Chinese medicine extract 7.5-21%, volatile oil 0.6652-1.1145%, cocoa extract 2-3%, coffee extract 2-4% and the balance of alcohol. The Chinese medicine tincture includes white peony tincture 4-8%, broad bean flower tincture 3-6%, rhizoma angelicae pubescentis tincture 4-7%, fenugreek tincture 2-5% and coffee tincture 5-9%. The Chinese medicine extract includes melilotus officinalis extract 2-6%, chrysanthemum extract 2-6%, angelica sinensis extract 1.5-4% and Acer pseudosieboldianum extract 2-5%. Similarly, the above method is suitable for reconstituted tobacco leaves, but not for tobacco leaves generated in the natural process. SUMMARY

[0086] The tobacco leaves of this comparative example are selected from Yunnan light flavor tobacco leaves, specifically, Yunyan 87 in Xiangyun County, Dali, and the tobacco leaves are not treated with the control agent before being baked.

[0087] Performance detection

[0088] Sensory evaluation: the tobacco leaf products of Examples 1 and 2 and Comparative Examples 1 to 12 are subjected to sensory evaluation by professional personnel according to the “scale value” single tobacco evaluation method, and the evaluation results are shown in Table 1.

[0089] Chemical component analysis: the tobacco leaf products of Examples 1 and 2 and Comparative Examples 1 to 12 are subjected to routine chemical component analysis, and the analysis results are shown in Table 2.

[0090] The experimental data and analysis are as follows:

[0091] Table 1 Sensory evaluation results

[0092]

[0093] Table 2 Chemical component analysis results

[0094]

[0095] As can be seen from Table 1, the sensory evaluation results of the Henan strong flavor tobacco leaves regulated by the method of the present application are obviously better than those of the tobacco leaves of Comparative Examples 1 to 11; the total sugar content and the total nitrogen content of the Henan strong flavor tobacco leaves regulated by the method of the present application are obviously higher than those of the tobacco leaves of Comparative Examples 1 to 11. And the sensory evaluation results of the Yunnan light flavor tobacco leaves regulated by the method of the present application are obviously better than that of the tobacco leaves of Comparative Example 12; the total sugar content and the total nitrogen content of the Yunnan light flavor tobacco leaves regulated by the method of the present application are obviously higher than those of the tobacco leaves of Comparative Example 12. Overall, the tobacco leaves treated by the regulating agent of the present application have more delicate aroma quality, more abundant aroma amount, more full smoke density, and better overall smoking quality.

[0096] Further, in the method of the present application, the glucose and fructose in the first regulating stock solution are important aroma precursor substances of tobacco leaves, which can promote the increase of the total sugar content of tobacco leaves by being sprayed on the surface of tobacco leaves, especially for the characteristics of low sugar content of Henan strong flavor tobacco leaves. And the reducing sugar is an important substrate of Maillard reaction and caramelization reaction, and after the baking process, the sugar can undergo Maillard reaction and caramelization reaction to generate a large amount of aroma substances, produce caramel sweet aroma and baking aroma, and improve the smoke density and the style characteristics of tobacco leaves.

[0097] Further, in the method of the present application, the L-amino acid in the second regulating stock solution is an important substrate of Maillard reaction, which can increase the total nitrogen content of Yunnan light flavor tobacco leaves, promote the Maillard reaction of tobacco leaves during the baking process, and thus improve the smoke density.

[0098] Further, in the method of the present application, the second regulating stock solution contains a certain amount of potassium salt, which can improve the quality of tobacco leaves and improve the combustibility of tobacco leaves.

[0099] The regulation method of the present application promotes the occurrence of Maillard reaction by exogenous supplement, i.e. the first regulation stock solution and the second regulation stock solution, and the Maillard reaction is a series of complex chemical reactions of reducing sugars and nitrogen-containing compounds. The glucose and fructose selected by the present application are typical reducing sugars. The tobacco leaf itself contains many sugar substances, most of which are polysaccharides such as starch and monosaccharides such as glucose and fructose, and the content of disaccharides is very low. Glucose and fructose are easily absorbed by tobacco as they are endogenous substances of tobacco and easily soluble in water. For tobacco, the specific composition and distribution of the naturally occurring sugar substances in the tobacco plant are directly related to the availability of the substrate of the Maillard reaction. In the curing of tobacco leaves, the main components of water-soluble sugars are glucose and fructose, which are two kinds of monosaccharides, and their proportion in the total amount of monosaccharides and disaccharides is much higher than that of disaccharides, which makes the tobacco cells have higher affinity and metabolic utilization rate for glucose and fructose. Moreover, when the exogenous supplement is consistent with the endogenous metabolism of sugar, it can more efficiently participate in the Maillard reaction. The comparative example 1 uses a combination of disaccharides, and the absorption rate of disaccharides by tobacco is low, and the reaction activity of disaccharides is low. The comparative example 2 uses a combination of monosaccharides and disaccharides, and the interaction of reaction intermediates may produce undesirable by-products, such as excessive 5-hydroxymethyl furfural, which brings an unpleasant irritation. The comparative examples 3 and 4 both use a single monosaccharide, and the single reaction path limits the diversity of products, resulting in a decrease in sensory evaluation of the product.

[0100] Further, the dilution concentrations of the first regulation stock solution and the second regulation stock solution in the comparative examples 5 to 8 are not within the range defined in the present application. When the dilution concentrations of the first regulation stock solution and the second regulation stock solution are too high, a sticky layer will be formed on the surface of the tobacco leaf, and high concentration is easy to burn the tobacco leaf, and in the later curing process, due to the residual of more substances on the surface of the tobacco leaf, it is easy to cause the tobacco leaf to be scorched, to be covered with ash, etc., affecting the appearance quality of the tobacco leaf. When the dilution concentration of the first regulation stock solution and / or the second regulation stock solution is too low, it cannot effectively supplement the relevant components of tobacco, which is not conducive to the subsequent occurrence of Maillard reaction and caramelization reaction.

[0101] Further, the regulation agent spraying methods of the comparative examples 9 and 10 are different from the spraying method defined in the present application. The comparative example 9 uses simultaneous spraying of the first regulation stock solution and the second regulation stock solution, which results in a large concentration of the regulation agent causing burns to the tobacco leaf. At the same time, simultaneous spraying of a large amount of regulation stock solution is not conducive to the rapid absorption of the liquid. And simultaneous spraying of the two regulation stock solutions is easy to interact with different reaction intermediates under the action of sunlight or active enzymes on the surface of the tobacco leaf, producing undesirable by-products and affecting the spraying effect. The comparative example 10 sprays the second regulation stock solution first and then sprays the first regulation stock solution. Since the absorption effect of the tobacco leaf on reducing sugars is lower than that of L-amino acids, it makes the absorption time of the effective substances of the first regulation stock solution by the tobacco leaf insufficient, thereby affecting the sensory evaluation and the total sugar content.

[0102] Further, the regulation method is mainly for Henan strong flavor tobacco leaves and Yunnan mild flavor tobacco leaves, and the main reason is that the sugar content and the amino acid content of tobacco leaves in these two production places are quite different. If it is used on tobacco leaves in other production places, the proportion of the first regulation stock solution and the second regulation stock solution needs to be adjusted according to the sugar content and the amino acid content of the local tobacco leaves.

[0103] The above embodiments only illustrate the principles and effects of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the present application should be covered by the claims of the present application.
