Example Embodiment

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

[0018] Soaking with water extracts the tobacco raw materials used for preparing tobacco flakes to extract the water-soluble tobacco. The tobacco raw material may be tobacco stems, dust, tobacco sticks, tobacco leaf fragments, tobacco rods, or a combination thereof produced by a cigarette factory. Generally, the tobacco raw materials used are a combination of the above, and the ratio between them is not specified. Generally, the ratio can be based on the amount actually produced during the production process of the cigarette factory. Before soaking, the tobacco raw materials can be mechanically crushed to crush the raw materials to a length of less than 30mm and a diameter of less than 5mm. Or, in this step, the crushing is not performed first, but the crushing is performed in the subsequent steps. Each 100g of the tobacco raw material can be soaked in 200-1000ml of water, preferably ...

Example Embodiment

[0026] Example one:

[0027] Mix the four production materials of tobacco stem, tobacco powder, tobacco stick and tobacco stick according to the ratio of 7:3:3:1, weigh 100g, soak in 700ml of water at 70℃ and stir for 40min, the stirring rate is 200 rpm (The stirrer is the S-312 digital thermostat stirrer of Shanghai Shensheng Technology Co., Ltd.). After squeezing and separating, 470ml of tobacco water-soluble extract is obtained, which is placed in the bioreactor (RS-type reaction of Shanghai Shenshun Biological Technology Co., Ltd.) Add 0.15g of liquid pectinase, at a temperature of 50°C and a stirring rate of 220 rpm, after 5 hours of enzymolysis, stop the reaction and kill the enzyme. The temperature is 95°C, and the time is 15 minutes. , Get the water-soluble extract of tobacco①.

[0028] Use a grinder (Shanghai Dianjiu Chinese Medicine Machinery Manufacturing Co., Ltd.'s grinder-slicing model) to mechanically crush the 310g of tobacco insoluble wet solids obtained after e...

Example Embodiment

[0032] Embodiment two:

[0033] The equipment used in this embodiment is the same as that in the first embodiment.

[0034] Mix the four production materials of tobacco stems, tobacco dust, tobacco sticks and tobacco sticks in a ratio of 6:2:2:1, weigh 100g, soak and stir in 800ml of water at 65°C for 35min at a stirring rate of 220 rpm After squeezing and separating, 550ml of tobacco water-soluble extract is obtained, placed in a bioreactor, adding liquid pectinase 0.20, at a temperature of 55℃, stirring rate of 220 rpm, enzymatic hydrolysis reaction 4h, stop the reaction The enzyme inactivation temperature is 100°C and the enzyme inactivation time is 10 minutes to obtain the water-soluble tobacco extract①.

[0035] The 320g tobacco insoluble wet solid obtained after extraction was mechanically crushed with a pulverizer for 15 seconds, placed in a bioreactor, 640ml of water and 0.20g of liquid neutral protease were added, at a temperature of 50°C, and a stirring rate of 250 rpm...

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...
