Problems solved by technology

However, enzymatic degradation before the leaching described in CN1836589A does not provide a suitable enzymatic buffer system, nor does it mention that the lignin that obviously produces lignin gas and some pungent sensations is degraded, so it is most important for reducing the tobacco sheet. Prominent woody smell, the effect of improving odor absorption is not significant

preparation example Construction

[0017] The specific process for preparing tobacco sheet of the present invention is as follows.

[0018] Soaking the tobacco raw material used for preparing the tobacco sheet with water to extract the tobacco water-soluble matter. The tobacco raw material may be tobacco stems, tobacco dust, cigarette sticks, tobacco leaf fragments, tobacco rods or combinations thereof produced by cigarette factories. Usually, the used tobacco raw materials are a combination of the above-mentioned types, and there is no special regulation on the ratio between them, and the ratio can generally be matched according to the actual amount produced in the cigarette factory production process. Before soaking, the tobacco raw material can be mechanically crushed to a length less than 30mm and a diameter less than 5mm. Alternatively, crushing is not performed in this step, but crushing is performed in a subsequent step. Every 100g of the tobacco raw material can be soaked in 200-1000ml of water, prefe...

Embodiment 1

[0027] Mix the 4 raw materials of tobacco stems, tobacco powder, tobacco sticks and cigarette sticks according to the ratio of 7:3:3:1, weigh 100g, soak and stir with 700ml of water at 70°C for 40min, and the stirring speed is 200 rpm (The agitator is the S-312 digital display thermostatic agitator of Shanghai Shensheng Technology Co., Ltd.), separated by pressing, to obtain 470ml of tobacco water-soluble extract, and put it into a bioreactor (the R-S type reaction of Shanghai Shenshun Biotechnology Co., Ltd.) Add 0.15g of liquid pectinase to a device), and at a temperature of 50°C and a stirring rate of 220 rpm, after the enzymolysis reaction for 5 hours, stop the reaction to inactivate the enzyme, the temperature for inactivating the enzyme is 95°C, and the time for inactivating the enzyme is 15 minutes , to obtain tobacco water-soluble extract ①.

[0028] The 310g tobacco insoluble wet solid obtained after leaching is mechanically crushed for 10 seconds with a pulverizer (t...

Embodiment 2

[0033] The equipment used in this example is the same as that in Example 1.

[0034] Mix the 4 raw materials of tobacco stems, tobacco powder, tobacco sticks and cigarette sticks according to the ratio of 6:2:2:1, weigh 100g, soak and stir in 800ml of water at 65°C for 35min, and the stirring speed is 220 rpm , separated by pressing to obtain 550ml of tobacco water-soluble extract, put it into a bioreactor, add liquid pectinase 0.20, at a temperature of 55°C and a stirring speed of 220 rpm, enzymolysis reaction for 4 hours, stop the reaction Inactivate the enzyme at a temperature of 100°C for 10 minutes to obtain a water-soluble extract of tobacco ①.

[0035] The 320g of tobacco insoluble wet solid obtained after leaching is mechanically crushed for 15 seconds with a pulverizer, put into a bioreactor, add 640ml of water, 0.20g of liquid neutral protease, at a temperature of 50°C, and a stirring rate of 250 rpm Separately, enzymolysis reaction 8h. After the reaction, squeeze ...

Abstract

The invention provides a technique for preparing tobacco sheets and the tobacco sheets. The technique comprises the following steps: soaking tobacco materials in water to obtain extract liquid and a water-insoluble solid; carry out enzymatic hydrolysis on the extract liquid by pectinase and / or protease so as to obtain a first water-soluble extract; degrading the protein in the water-insoluble solid by the protease so as to obtain an enzyme-hydrolyzed water-insoluble solid and a second water-soluble extract; placing the enzyme-hydrolyzed water-insoluble solid in acidic alcohol solution so as to acid-degrade lignose, then preparing the separated solid into tobacco sheet bases; and carrying out vacuum concentration on the first and the second water-soluble extracts and applying the first and the second water-soluble extracts to the tobacco sheet bases to prepare the tobacco sheets. The technique can effectively reduce the content of water-soluble pectin and water-insoluble protease, and reduce the unique lignin flavor in the tobacco sheets by the chemical degradation of the lignose.

Description

technical field [0001] The invention relates to a tobacco processing technique, in particular to a technique for preparing high-quality tobacco sheet by degrading biological macromolecules in tobacco raw materials, and also relates to the tobacco sheet produced by the technique. [0002] It is mainly the enzymatic chemical treatment of tobacco raw materials after extraction, that is, adding enzyme preparations and chemical reagents to tobacco stems, tobacco powder, tobacco sticks, tobacco leaf fragments and tobacco sticks according to the solubility and chemical properties of biological macromolecules after extraction. Carry out pretreatment of production raw materials, so that the tobacco macromolecular substances that are not conducive to burning and smoking are converted into small molecular substances or removed, so as to improve the burning and smoking taste and improve the quality of tobacco. Background technique [0003] Tobacco sheet, also known as recombined tobacco...
