The expression "and / or" in combination with three or more recited items should be understood to have the same meaning, unless otherwise understood from the context.

[0025] The use of the terms "comprising", "having" or "containing", including their grammatical synonyms, should generally be understood as open and non-restrictive, for example not excluding other unrecited elements or steps, unless otherwise specifically stated or otherwise understood from the context.

[0026] In this application, the term "and / or" describes the association relationship of associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. A and B can be singular or plural.

[0027] The present invention provides a method for improving the quality of heated cigarette thin-sheet tobacco, comprising:

[0031] The method for improving the quality of heated cigarette thin-sheet tobacco provided by the present invention firstly mixes tobacco powder and wet materials.

[0032] The tobacco powder of the present invention is obtained by crushing tobacco shreds. The present invention does not limit the type of tobacco shreds, and any type known in the art can be used. The crushed mesh size is preferably 80-200 meshes.

[0033] The wet material includes an atomizer and water; the atomizer includes glycerol or propylene glycol; and the mass concentration of the atomizer in the wet material is 15%-30%.

[0044] In one of the preferred embodiments of the present invention, the parameters of the hydrothermal treatment are: boiling in water at 80° C. for 45 minutes.

[0045] The inventors have found that hydrothermal and baking conditions promote the Maillard reaction of tobacco raw materials, which is beneficial to improving the tobacco aroma and baking aroma characteristics of heated cigarettes.

[0046] The slurry is prepared into thin sheets by a thick slurry method, and then dried, shaped, and cut into shreds to obtain heated cigarette thin-sheet shredded tobacco.

[0047] The present invention does not limit the specific preparation method of the thick slurry method, which is well known to those skilled in the art.

[0048] The drying is preferably carried out by baking at 90-110° C. for 3-5 minutes.
