Abstract

The invention relates to a coffee roasting aroma reconstituted tobacco leaf and a preparation method and application thereof. The preparation method comprises the following steps: the step (1) preparing coffee roasting aroma substance; the step (2), preparing coffee roasting aroma reconstituted tobacco leaves. The invention can remove smoke irritation or foreign gas substance such as macromolecular substance to obtain pure roasting aroma substance, which is added into recycled tobacco leaf coating liquid and coated on reconstituted tobacco leaf, and can greatly improve the aroma and taste of rich cigarettes, reduce the amount of foreign gas, and improve the comfort and coordination of cigarettes. The coffee roasting aroma substance of the invention and baicalin are compounded and can remarkably reduce the free radical content in the smoke. The preparation method of the invention has the advantages of simple operation, safe product and wide application prospect.

Description

technical field [0001] The present invention relates to a method for preparing reconstituted tobacco leaves, in particular to a method for preparing reconstituted tobacco leaves with roasted coffee aroma, and also relates to the roasted coffee aroma reconstituted tobacco leaves with reduced smoke free radical content obtained by the preparation method and their application, belonging to tobacco The field of excipients. Background technique [0002] As cigarette consumers pay more and more attention to their own health and have higher and higher requirements for the intrinsic quality of cigarettes, low-tar and high-quality cigarettes have become the focus of current coffee research. However, low tar must be accompanied by loss of cigarette aroma and poor comfort. In terms of quality, the current domestic cigarette products have certain deficiencies in smoking quality and sensory comfort, such as weak aroma, strong dryness, insufficient sweetness, and poor comfort. [0003] ...
