Abstract

The invention discloses a preparation method of a compound fruit extract. The steps include: (1) chopping fresh mulberry and lentil indigo fruit, heating and boiling them in an aqueous solution of gallic acid for pretreatment, and separating the solid and liquid after the pretreatment to obtain the treated liquid and The solid phase filtrate; (2) extracting the solid phase filtrate with a compound enzyme; (3) mixing the filtrate after inactivating the enzyme with the treated liquid, concentrating under reduced pressure, adding hydrogen peroxide to the concentrated liquid, filtering to remove the precipitate, After heating and cooling to room temperature, the composite extract of mulberry and indigo fruit is obtained; (4) the fresh cherries are chopped and ultrasonically extracted in an ethanol solution containing nonalactone, and the extract is concentrated under reduced pressure to obtain cherries Extraction solution; (5) Mix the compound extract solution of mulberry and indigo fruit and the extract solution of Prunus cerevisiae evenly to obtain a compound fruit extract. After the present invention mixes the cherries extract and the compound extract of mulberry / indigo fruit, the miscellaneous gas and irritation of the smoke can be obviously coordinated, the aroma of the obtained extract is richer and finer, and the smoking taste of cigarettes is improved.

Problems solved by technology

However, the existing fruit extracts have a single direction and way of improving the smoke, or the aroma is strong and strong, and the irritation to the smoke is improved well, but the original tobacco flavor of the cigarette is insufficient, the coordination is poor, and the aftertaste is insufficient, so it is difficult to achieve the effect of smoking tobacco. Or the aroma and smoke are well coordinated, but the aroma is too mild, the aroma quality is insufficient, there are more miscellaneous gases, and the irritation is large
