摘要： 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.

摘要： An extraction method of a flavor constituent comprises: a step A for heating a tobacco raw material which is subjected to an alkali treatment; and a step B for bringing a release component released in the gas phase in the step A into contact with a collection solvent at normal temperature until any time from when a first condition is satisfied to when a second condition is satisfied. The first condition is determined based on a residual rate of nicotine component. The second condition is determined based on a remaining amount of nicotine component.

摘要： Concentrated tobacco extracts or essences are provided by first extracting water soluble components from tobacco. The aqueous extract then is contacted with supercritical carbon dioxide, and certain tobacco components in turn are extracted from the aqueous extract. Alternatively, the aqueous extract is subjected to a spray drying step, and the spray dried extract is contacted with supercritical carbon dioxide in order that certain tobacco components are extracted from the spray dried extract. The resulting extracted components are separated from the supercritical fluid in order to yield a tobacco essence. The essence has a homogeneous, viscous character and exhibits a tobacco aroma. The essence is useful as a flavoring agent for cigarettes and other smoking articles.
