Description

Technical Field

[0001] The invention relates to the technical field of flavors, and in particular to a tobacco flavor containing a tobacco flower extract, and a preparation method and application thereof. Background Art

[0002] With the continuous improvement of living standards, consumers are paying more and more attention to the smoking quality and safety of cigarettes. Improving the safety of smoking has gradually become a common goal for the tobacco industry to survive and develop. At present, the amount of tar is generally used as a standard for judging the safety of cigarettes. Therefore, one of the main development directions of cigarette products is to reduce the tar content of cigarettes. As we all know, cigarettes are a kind of hobby product. With the substantial reduction of tar, the original aroma quality of tobacco leaves is bound to be affected. It will become increasingly difficult to maintain the smoking taste of cigarettes while further reducing tar. At present, the main method of adding flavors is to maintain the original aroma characteristics of cigarettes. Tobacco flavors can cover up the shortcomings of tobacco, improve the aroma and taste of tobacco, and improve the physical properties of tobacco. It also gives cigarettes a unique taste and style, realizes the differentiation of product quality, stabilizes the quality of cigarette smoking, and has an important influence on the formation of cigarette style and quality.

[0003] Sucrose tetraesters, which are mainly present in the wax on the surface of tobacco, are a very important aroma precursor. During the burning and smoking process of tobacco leaves, they will be cracked to release aroma components such as isobutyric acid, isovaleric acid, and 3-methylbutyric acid. These components can make cigarette smoke softer and enhance the sweetness of smoke, thereby improving the aftertaste and enhancing coordination, and significantly improving its aroma quality. Due to the special structure of sucrose tetraesters contained in tobacco, chemical synthesis is very difficult, and there is no industrial product yet. It can only be separated and extracted from tobacco.

[0004] Tobacco flowers are a byproduct of tobacco production and are discarded after the tobacco leaves are toppled, which not only wastes resources but also pollutes the environment. Studies have found that the content of sucrose tetraesters in tobacco flowers is significantly higher than that in tobacco leaves. Traditional tobacco flower extracts contain a large amount of lipid components, which will generate harmful substances such as polycyclic aromatic hydrocarbons when added to cigarettes and burned. Therefore, the application of tobacco flower extracts in cigarettes is limited. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a tobacco flavor containing tobacco flower extract and a preparation method and application thereof. The flavor has strong compatibility with cigarette products. The use of the flavor can make cigarette smoke softer, enhance the sweetness of the smoke, significantly improve its aroma quality, improve the aftertaste, and enhance coordination.
