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

preparation example Construction

[0036] The invention provides a method for preparing a heat-not-burn tobacco sheet, comprising the following steps:

[0037] a) subjecting the tobacco leaves to biological treatment under the action of microorganisms to obtain primary biologically treated tobacco leaves;

[0038] The microorganisms include bacillus and / or yeast;

[0039] b) mixing the primary biologically treated tobacco leaves with mint to obtain a mixture;

[0040] c) after water extraction and concentration of the mixture, adding a complex enzyme preparation for biological treatment to obtain a secondary biological treatment concentrate;

[0041] The compound enzyme preparation includes two or more of cellulase, pectinase, protease and glucose enzyme;

[0042] d) mixing the secondary biological treatment concentrate with a modifier to perform a Maillard reaction to obtain a coating material;

[0043] e) coating the coating material on the surface of the tobacco sheet and drying it to obtain a heat-not-bu...

Abstract

The invention provides heat-not-burn tobacco sheets and a preparing method thereof. The preparing method comprises the steps of a, conducting biological treatment on tobacco leaves under the effect ofmicroorganisms to obtain primary biological treatment tobacco leaves; b, mixing the primary biological treatment tobacco leaves with mints to obtain a mixture; c, conducting aqueous extract and concentration on the mixture, and afterwards adding a complex enzyme preparation into the mixture to conduct biological treatment to obtain a secondary biological treatment concentration solution; d, mixing the secondary biological treatment concentration solution with a modifier to be subjected to a Maillard reaction to obtain a coating medium; e, coating the matrix surface of the tobacco sheets withthe coating medium and drying the surface to obtain the heat-not-burn tobacco sheets. According to the preparing method of the heat-not-burn tobacco sheets, the tensile strength of the heat-not-burn tobacco sheets can be improved, and the heat-not-burn tobacco sheets are not easily adhesive and convenient to clean; meanwhile, bad smell like woody mixed gas is fundamentally removed, and the heat-not-burn tobacco sheets have the flavor of the mints.

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...
