Problems solved by technology

In the existing cocoa fragrance extraction technology, water extraction or alcohol extraction process is generally used. According to the principle of "like dissolves like", simple water extraction or alcohol extraction process can only extract components with similar or similar polarities to the extraction solvent, and other extremely Components with large differences in properties and extraction solvents cannot be effectively extracted, and the effective comprehensive utilization of cocoa cannot be realized

Abstract

The invention provides a multi-stage solvent extraction preparation method of cocoa extract and application. Cocoa 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 the filtrate extracted three times was mixed evenly and concentrated to obtain cocoa extract. The invention hasthe advantages of simple process, mild conditions, easy operation, non-complicated separation and purification process, cost saving, safety and environmental substances that being used to ensure thatalkaline, neutral and acidic components in cocoa being extracted as far as possible, thereby expand the application range and application value of cocoa extract. The cocoa extract obtained by the invention is applied to traditional cigarettes and heated non-combustible cigarettes, and has good application effect.

Description

technical field [0001] The invention relates to the technical field of tobacco additives, in particular to a multi-stage solvent extraction preparation method of cocoa 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 re...
