Heat-not-burn tobacco sheet and preparation method thereof

Abstract

The invention provides a heat-not-burn tobacco sheet and a preparation method thereof. The preparation method includes: a) subjecting tobacco leaves to biological treatment under the action of microorganisms to obtain primary biologically-treated tobacco leaves, wherein the microorganisms include bacillus and / or saccharomycetes; b) mixing the primary biologically-treated tobacco leaves with rhodiola rosea to obtain a mixture; c) after aqueous extraction and concentration of the mixture, adding a complex enzyme preparation for biological treatment to obtain secondary biologically-treated concentrated liquor, wherein the complex enzyme preparation comprises two or more of cellulase, pectinase, protease and glucolase; d) mixing the secondary biologically-treated concentrated liquor with a modifying agent to obtain a coating material through Maillard reaction; e) coating the surface of a tobacco sheet base with the coating material, and drying to obtain the heat-not-burn tobacco sheet. Byadoption of the preparation method, tensile strength and bulkiness of the tobacco sheet can be improved while the tobacco sheet is less prone to adhesion, bad smells such as offensive wood odor are almost eliminated, and an aroma of rhodiola rosea is achieved.

Description

technical field [0001] The invention relates to the technical field of tobacco, in particular to a heat-not-burn tobacco sheet and a preparation method thereof. Background technique [0002] Tobacco flakes, also known as reconstituted tobacco leaves, are waste tobacco materials such as tobacco stems, tobacco powder and some low-grade tobacco leaves that are discarded in the cigarette production process to form products with shapes close to or better than natural tobacco leaves, and then used in cigarette production. It can effectively reduce the production cost of cigarettes, and can also reuse the waste from cigarette production, so as to achieve the effect of reducing consumption and increasing efficiency. Therefore, tobacco sheet has become a necessary raw material for cigarette formula, and because tobacco sheet has these important practical significance, its production develops very rapidly. [0003] Traditional tobacco products have been used as a luxury product for h...

AI Technical Summary

Problems solved by technology

However, in the existing low-temperature heat-not-burn cigarettes, the dry flakes formed by tobacco powder and binder are usually used as shredded tobacco. When heated, the smell of wood is heavier, the taste is relatively single, and the irritation is obvious; The tensile strength of the sheet is low, the bulk is not good, the shredded tobacco is easy to stick, the cutting blade is easy to stick during the processing, and after being made into a cigarette, it cannot be pulled out smoothly after smoking, and the shredded tobacco is easy to stick to the heating element. difficulty
