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 grass coral 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...

Abstract

The invention provides a reconstituted tobacco incombustible after being heated and a preparation method thereof. The preparation method comprises the steps that biological treatment is carried out ontobacco leaves under the action of microorganisms to obtain primary biological treatment tobacco leaves; the primary biological treatment tobacco leaves are mixed with sarcandra glabra to obtain a mixture; water extraction and concentration are carried out on the mixture, and a complex enzyme preparation is added for biological treatment to obtain a secondary biological treatment concentrated solution; the secondary biological treatment concentrated solution is mixed with a modifier for a Maillard reaction to obtain a coating material; the surfaces of reconstituted tobacco bases are coated with the coating material and dried to obtain the reconstituted tobacco incombustible after being heated. By means of the preparation method, the tensile strength and bulk of the reconstituted tobacco incombustible after being heated can be improved, and the reconstituted tobacco is not likely to adhere; meanwhile, the wood offensive odor and other bad smells are basically eliminated, and the reconstituted tobacco has the smell of sarcandra glabra.

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...
