Method for preparing tobacco extractive by biological enzyme

Abstract

Disclosed is a method for preparing tobacco extractive by biological enzyme, which comprises using minced tobacco, low grade tobacco leaves as raw material, charging pectolase, cellulose and hemicellulase, or the complex enzyme of enzymes selected from above for enzymolysis, thus hydrolyzing macromolecules of the pectolase or cellulose into micromolecular substances helpful for enhancing and improving scent for tobacco extracts, a second enzymolysis can also be carried out by charging aliphatic acid enzyme, cigarette alkali degradation enzyme or beta-glucosidase.

Description

technical field

[0001] The invention relates to a method for preparing spices, in particular to a method for preparing different-quality tobacco extracts by using various biological enzymes to treat tobacco dust, low-grade tobacco leaves and tobacco leaves. Background technique

[0002] In the past ten years, some domestic spice manufacturers and research institutes have successively carried out the research and production of tobacco extract, and successively developed natural tobacco flavors such as Burley tobacco extract, Yunyan extract and sun-cured red tobacco extract. Yang Yibing extracted tobacco raw materials with water, acidified the extract, distilled and concentrated the extract after acidification, redistilled the concentrate to obtain volatile oil, precipitated the concentrate of the extract with alcohol, recovered alcohol and added volatile oil to obtain tobacco extract. Han Guizhong and Yang Yibing used the waste materials of sun-cured red tobacco, such as toba...
