[0007] Chinese patent publication CN 1694628A "method for reducing nitrogen-containing compounds and lignin in tobacco", US patent publication US2006 / 0037620A1 removes protein and other biomolecules from tobacco extract or slurry (Process to remove protein and other biomolecules from tobaccoextract or slurry), U.S. Patent Publication US2006 / 0130859A1 reduces the process of reducing nicotine-containing compounds and lignin from tobacco (process for reducing nitrogen containing compounds and lignin in tobacco), using the tobacco that is separated after extraction The fiber is chemically treated (hydrogen peroxide is added under alkaline conditions), and the residual chemicals have a certain impact on the quality of the tobacco sheet, and the application is very limited
But so far, there has been no application of mimic enzymes in the tobacco industry and the production of paper-making tobacco sheets

Abstract

The invention discloses a method for reducing the content of lignin in papermaking tobacco sheets, belonging to the technical field of cigarette tobacco sheets. The method comprises the following step: at the tobacco raw material pulping state of the papermaking tobacco sheet production process, adding mimic enzyme according to a proportion of 1-6.5% of the dry weight of tobacco pulp material, wherein the temperature of the tobacco pulp material during the addition of the mimic enzyme is 25-40 DEG C, and after the addition, the temperature is kept for 20-40 minutes. The mimic enzyme formula comprises the following components by weight percent: 10-35% of FeSO4.7H2O, 5-20% of citric acid, 2-15% of oxalic acid and 20-60% of water. The mimic enzyme is obtained by the following steps: firstly adding the FeSO4.7H2O in the water at the temperature of 25-45 DEG C; then adding citric acid and oxalic acid; and mixing uniformly. The method provided by the invention is simple to operate and marked in effect, and is capable of decreasing the content of the lignin in the papermaking tobacco sheets and enhancing the smoking quality.

Description

technical field [0001] The invention belongs to the technical field of cigarette tobacco sheets, and in particular relates to a method for treating tobacco slurry with a simulated enzyme system to remove lignin in the production of tobacco sheets. Background technique [0002] In the prior art, tobacco flakes, also known as recombined tobacco, are regenerated products made of tobacco materials such as tobacco powder, tobacco stems, and shredded tobacco pieces as raw materials, and are used as cigarette fillers. Similar to tobacco. There are many ways to make tobacco sheets, and the commonly used methods are roll pressing, thick pulp method and paper making method. The typical papermaking tobacco sheet production method is to soak the raw material in water, extract and separate the soluble matter from the insoluble matter, beat the insoluble matter tobacco fiber (or add some wood pulp fiber), and use a paper machine to form a sheet base; The soluble extract is concentrated,...
