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 valerian 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 valerian fragrance.

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 tea leaves 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 thecoating 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 the tea leaves.
