The invention discloses a preparation method of a subcritical raisin extract and an application of the subcritical raisin extract in cigarettes. The subcritical raisin extract is characterized by being prepared by the following method: pretreating raw materials and extracting at an extraction pressure of 0.5MPa to 3MPa at the temperature of 0-50 DEG C by taking butane, propane or dimethyl ether as a subcritical extracting solvent, wherein an entrainer used is 55% to 95% ethanol. After being added with the subcritical raisin extract, cigarette shreds are free of peculiar smells in smoke and harmonious in fragrance; due to the subcritical raisin extract, the fragrance quality and the smoke fineness and tenderness of the cigarettes are both improved; the fragrance amount of the cigarettes is increased; impurity gas and irritation of the smoke are reduced; the overall smoking quality of the cigarette is improved. The most prominent characteristics of the subcritical raisin extract prepared by the method disclosed by the invention are that the subcritical raisin extract prepared by the method can be used as a cigarette additive, the application of the additive does not change the original performances and processing technique of the cigarettes, the fragrance quality of the cigarettes is improved and the sensory comfort degree of the cigarettes is increased, so the subcritical raisin extract has better significance and value for actual production.
