Description

Technical Field

[0001] The invention relates to the technical field of processing and extracting tobacco flavors, and in particular to a high-efficiency extraction device and extraction process for Henan tobacco reactants. Background Art

[0002] Tobacco extract is one of the most important raw materials for flavoring Chinese cigarettes. It is used in huge quantities and has the function of strengthening the characteristic aroma of tobacco and improving the sensory quality of cigarettes. Henan tobacco reactant (i.e. Henan tobacco extract) is an extract from Henan tobacco leaves, which has typical strong aroma characteristics. Adding it to cigarettes can further highlight the roasted sweet aroma and strong aroma, enhance the explosiveness and strength of smoke, and increase the concentration and permeability of smoke. It accounts for a large proportion in the flavoring of products of various cigarette industrial enterprises. By rationally utilizing Henan tobacco extract, cigarette industrial enterprises can alleviate the contradiction of insufficient supply of high-quality tobacco leaf raw materials in Henan to a certain extent.

In addition, the aroma compounds contained in this Henan tobacco extract are limited, which cannot effectively highlight the style of cigarettes and bring some negative effects to cigarettes.
