Preparation method of reconstituted tobacco

Abstract

The invention provides a preparation method of reconstituted tobacco. The preparation method comprises the following steps of: 1, uniformly mixing tobacco stems, tobacco powder and water, then adding a cell disruption enzyme and an assistant I for carrying out enzymatic hydrolysis; 2, heating and extracting a mixture in the step 1, carrying out enzyme deactivation, then filtering to obtain filtrate and filter residue, concentrating the filtrate to obtain a concentrated solution; 3, adding a mixed culture and an assistant II in the concentrated solution, carrying out fermentation and enzymatic hydrolysis to obtain a tobacco extraction solution; 4, adding slurry in the filter residue in the step 1, uniformly mixing, adding hydrogen peroxide for carrying out oxygenolysis, then adding catalase for hydrolyzing residual peroxide to obtain mixed slurry; and 5, preparing the mixed slurry into a slice paper base, coating the tobacco extraction solution on the slice paper base, drying and preparing into the reconstituted tobacco. According to the preparation method of the reconstituted tobacco, the mixed culture is fermented in the concentrated solution, and thus the content of lignin can be reduced, and the smoking effect is improved.

Description

technical field [0001] The invention relates to a tobacco processing technology, in particular to a method for preparing reconstituted tobacco leaves. Background technique [0002] my country's tobacco planting area is 20 million mu, and the annual tobacco leaf output is 4.5-5 million tons, ranking first in the world. Tobacco grown at home and abroad is mainly used as cigarettes. The cigarette industry mostly uses high-quality tobacco leaves as raw materials. About 25% of tobacco leaves, tobacco powder and other leftovers are discarded. If they are discarded or handled improperly, they will cause environmental pollution. The "resource" utilization of these tobacco wastes can not only obtain a variety of useful products, but also provide an opportunity for sustainable development for enterprises to tap their potential and transform, and can also reduce soil and soil pollution caused by tobacco waste, avoiding harmful Contamination of groundwater by ingredients. Therefore, s...

AI Technical Summary

Problems solved by technology

The physical treatment method has a high treatment intensity, and the loss of the aroma components in the tobacco stem is relatively large, which affects the smoking quality of the cigarette. At the same time, it cannot change its inherent microstructure, and it is difficult to make the nanomaterials effectively adsorb

2. Chemical treatment methods, mainly using dilute acid, alkali, ozone, organic solvents and oxidation, etc., chemical treatment methods have the problem that chemical substances are difficult to deal with in the later stage of production

3. Biological treatment method. Biological treatment mainly uses biological enzymes or bacteria to degrade the cell wall components of tobacco stems. Only biological enzymes are used to treat tobacco stems to produce reconstituted tobacco leaves. Since plant cell walls are the natural protective barrier of plants, enzyme treatment is often not thorough. , can only degrade part of the cell wall components; a long treatment time with bacteria alone will cause the cell wall to completely collapse, affecting the quality of reconstituted tobacco leaves, and the goal cannot be achieved if the time is short
