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 Lycium barbarum leaves 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 ob...

Abstract

The invention provides a heat-not-burn tobacco sheet and a preparation method thereof. The preparation method comprises the steps that tobacco leaves are subjected to biological treatment under the action of microorganisms to obtain the primary biologically-treated tobacco leaves; the primary biologically-treated tobacco leaves and boxthorn leaves are mixed to obtain a mixture; after the mixture is subjected to aqueous extraction and concentration, a compound enzyme preparation is added for biological treatment to obtain a secondary biologically-treated concentrated solution; the second biologically-treated concentrated solution and a modifier are mixed for Maillard reaction to obtain a coating medium; a tobacco sheet base is coated with the coating medium and dried to obtain the heat-not-burn tobacco sheet. By means of the preparation method, the tensile strength and the bulk of the heat-not-burn tobacco sheet can be improved, the heat-not-burn tobacco sheet is not likely to adhere, meanwhile, bad odor such as wood offensive odor is basically eliminated, and the heat-not-burn tobacco sheet has fragrance of the boxthorn leaves.

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...
