Problems solved by technology

In the existing jasmine fragrance extraction technology, jasmine essential oil is generally prepared by methods such as steam distillation or supercritical extraction, and jasmine absolute oil is generally obtained by ethanol extraction of jasmine extract or jasmine extract, but only the volatile and semi-volatile components; jasmine extract generally adopts water extraction or alcohol extraction process. According to the principle of "like dissolves like", simple water extraction or alcohol extraction process can only extract components whose polarity is similar or similar to that of the extraction solvent. Others Components with a large difference in polarity and extraction solvent cannot be effectively extracted, and the effective comprehensive utilization of jasmine cannot be realized

Abstract

The invention provides a sectional extraction preparation method of jasmine flower extract and application. Jasmine flower was extracted with acidic ethanol-water solvent for the first time, neutral ethanol-water solvent for the second time, alkaline ethanol-water solvent for the third time, and two or three combinations of filtrates extracted three times were concentrated to obtain jasmine flowerextract. The above method has the advantages of simple process, mild conditions, easy to operate, without complicated separation and purification process and cost saving. Various used substances aresafe and environment-friendly to make sure that alkaline, neutral and acidic components in the jasmine flower can be extracted as far as possible, and a plurality of jasmine flower extract with different functional effects can be obtained through one experiment, which greatly expands the application range and application value of the jasmine flower extract. The series of jasmine flower extracts obtained by the invention are applied to traditional cigarettes and heated non-combustible cigarettes, and have good application effect.

Description

technical field [0001] The invention relates to the technical field of tobacco additives, in particular to a preparation method of segmental extraction of jasmine flower extract and its application. Background technique [0002] Flavors and fragrances in cigarettes can modify or cover up the defects of tobacco leaves, improve the aroma and taste of tobacco, improve the physical properties of tobacco, reduce the harmful components of cigarettes, endow cigarettes with unique taste and style, and realize product quality differences It can stabilize the smoking quality of cigarettes and have an important impact on the style and quality of cigarettes. In the formation of the core technology of "Chinese-style cigarettes", the role of flavors and fragrances will become more and more important, especially in meeting consumer needs, building unique style characteristics of cigarettes, and improving cigarette quality. At the same time, in order to improve the safety of smoking, harm ...
