Abstract

The invention discloses a preparation method of a prune extract and application of the prune extract in a cigarette. The preparation method comprises the following steps: denucleating prunes, juicingthe prunes to obtain juice, then filtering the prune juice, vacuum sterilizing at a certain temperature, performing liquid-liquid extraction on the sterilized prune juice by using ethanol, then cooling, filtering, and vacuum concentrating until a soluble solid is formed, thus obtaining the prune extract. The prune extract is diluted by using absolute ethyl alcohol to a certain ratio and then is atomized and sprayed into tobacco shreds, so that the cigarette fragrance can be enriched, the fruit fragrance and acid fragrance can be added, the cigarette can have mild smoking incense, and the dryness of smoke can be reduced.

Description

technical field [0001] The invention belongs to the field of cigarette additives, and in particular relates to a preparation method of prune extract and its application in cigarettes.
