Problems solved by technology

[0005] Due to the high-vacuum system of molecular distillation technology, the fragrance raw materials suitable for molecular distillation treatment are generally liquid fragrances with good fluidity that do not contain low boiling point solvents such as alcohol and water. Therefore, supercritical extraction of fragrance raw materials is generally used to directly enter molecular distillation. process, or petroleum ether, ethanol and other solvents to remove the low-boiling solvent, and then carry out the molecular distillation process, especially the aroma raw materials that use water as the solvent, due to the hydrogen bond force of water, it is not easy to completely remove, enter the molecular distillation process Finally, it is easy to cause bumping in a high vacuum environment, bringing unevaporated heavy components into the condensate surface, affecting the distillation effect

Abstract

The invention provides a preparation method of aromatic tobacco extract and application thereof in cigarettes. The preparation method includes: adding an aromatic tobacco raw material into an extraction tank, adding a high-boiling-point solvent in a weight of 5-30 times that of the raw material, and heating to 40-150 DEG C for extraction for 0.5-4h; removing solid aromatic tobacco raw material by filtration to obtain liquid crude extract, and putting the liquid crude extract in a molecular distillation equipment material tank for molecular distillation to obtain a light component and a heavy component, wherein the heavy component is the aromatic tobacco extract with the solvent removed. By directly adding the aromatic tobacco extract into cut tobacco for perfuming or by adding the same into essence for perfuming, aroma quality and aroma quantity of the cigarettes can be improved, smoke concentration can be increased, sweetness of the cigarettes can be improved, and irritation of the cigarettes can be lowered.

Description

technical field [0001] The invention belongs to the field of preparation of tobacco spices, and in particular relates to a method for preparing an oriental tobacco extract by using molecular distillation technology, and the application of the oriental tobacco extract prepared by the method in cigarettes. [0002] Background of the invention [0003] Many aroma components in oriental tobacco extract have high utilization value, such as furfural, isovaleric acid, solanone, macrostigmatrienone, geraniol, and sclareolactone, etc., are important raw materials for cigarette flavoring , Widely used in the tobacco flavor industry. However, traditionally extracted oriental tobacco extracts contain a large amount of protein and other macromolecular substances, which have the disadvantages of increasing irritation and residue while enriching smoke and flavoring, which affects the flavoring effect of cigarettes. Therefore, it is necessary to further process the oriental tobacco extract ...
