Problems solved by technology

In the existing perilla fragrance extraction technology for cigarettes, perilla oil is generally prepared by steam distillation or supercritical extraction, but only the volatile oil components can be extracted; perilla extract is generally prepared by water extraction or alcohol extraction. , according to the principle of "like dissolves like", the simple water extraction or alcohol extraction process can only extract components with similar or similar polarities to the extraction solvent, and other components with a large difference in polarity from the extraction solvent cannot be effectively extracted and cannot be realized Effective Comprehensive Utilization of Perilla Leaves

Abstract

The invention provides a sectional extraction preparation method of perilla extract and application. Perilla frutescens leaves were 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 a combination of three kinds of filtrates extracted three times were concentrated to obtainperilla frutescens extracts. The above method has the advantages of simple proces, mild conditions, easy to operate, without complicated separation and purification process and cost saving, safety and environmental substances that being used to ensure that alkaline, neutral and acidic component can be extracted in the perilla leaves as far as possible, and a plurality of perilla extracts with different functional effects can be obtained through one experiment, which greatly expands the application range and application value of the perilla extract. The series of perilla 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 segmented perilla 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 reduction and coke re...
