Problems solved by technology

Most of the aromatic substances of flowers exist in the form of glycosidic bonds, which are difficult to release.
If conventional preparation method is used to obtain spices, the yield of aroma substances in spices is low, so that the smoke fragrance of jasmine flower extract in cigarettes is not obvious, thereby limiting the application of jasmine flower extract in cigarettes

Abstract

The invention provides a method for preparing a jasmine extract for tobacco, belongs to the technical field of tobacco and relates to a method for preparing a spice for tobacco. The method comprises the following steps of: 1) taking dry jasmine, and adding water for reflux extraction to obtain jasmine extracting solution; 2) treating the jasmine extracting solution by using beta-glucosidase; and 3) filtering the extracting solution treated by enzyme, concentrating the filtered jasmine extracting solution under reduced pressure, performing sedimentation treatment, filtering, and collecting to obtain the jasmine extract for tobacco. The jasmine extract is treated by the beta-glucosidase, latent aromatic substances in the jasmine are hydrolyzed, latent aromatic components of the jasmine are released, the extracting yield of the aromatic substances in the jasmine are greatly improved, the production cost is reduced, and the characteristic spice for tobacco with richer aroma and higher quality is obtained. The invention improves the quality of the jasmine extract and realizes the application of the jasmine extract in cigarettes.

Description

Technical field [0001] The invention relates to a method for preparing tobacco flavors and fragrances, in particular to a method for preparing a jasmine flower extract for tobacco. Background technique [0002] In tobacco products, the aroma and taste of tobacco are very important. Adding flavor is a key link in the cigarette process. It is also one of the effective means to improve the product style and improve the quality of cigarette aroma. It can provide consumers with some aroma and flavor. Cigarette products with satisfactory taste. At present, most of the tobacco flavors added to tobacco in my country are prepared by traditional methods, that is, natural extract monomers and synthetic monomers are mixed and formulated. Although the tobacco flavors prepared in this way are simple in market operation, they still exist The aroma is monotonous, the improvement of tobacco is insufficient, and the effect of improving the smoking quality of cigarettes is not obvious. [0003] The ...
