The present disclosure provides a method for extracting tar aroma components from a cigarette butt and use of the tar aroma components in a cigarette. The method includes the following steps: (1) adding the cigarette butt to an extraction solvent, and carrying out ultrasound-assisted extraction to obtain an extraction solution; (2) centrifuging the extraction solution, and carrying out vacuum distillation on the supernatant to obtain a concentrated extractum; and (3) carrying out molecular distillation on the concentrated extractum, and collecting a light fraction of the molecular distillation to obtain the tar aroma components. In the present disclosure, the cigarette butt is used as a raw material, through the ultrasound-assisted extraction and separation by the molecular distillation to extract the tar, harmful substances in the tar are removed, and the aroma components are retained. The tar aroma components are applied to a heat-not-burn cigarette, so that the aroma, smoke and taste characteristics of the heat-not-burn cigarette are improved, and the problems of insipidness and uneven aroma release of the heat-not-burn cigarette are solved effectively.

A method for preparing a black liquor according to the present invention comprises digesting a tobacco raw material under an alkaline condition to obtain the black liquor. Further, a method for preparing a flavor component-containing liquid according to the present invention comprises digesting a tobacco raw material under an alkaline condition, separating the obtained digesting product into a black liquor and a tobacco fiber, and desalinating the black liquor to obtain the flavor component-containing liquid.

A smokeless tobacco composition for oral use comprising liberated, delignified tobacco fibers, a method for its manufacturing and use, as well as a pouch comprising the composition.
