Problems solved by technology

[0003] In order to make the style of cigar-shaped cigarettes made of reconstituted tobacco closer to cigars, it is usually necessary to dye the reconstituted tobacco, but the reconstituted tobacco produced by the prior art has unstable color and a large difference in hue compared with cigars. gap
And some natural pigments have better dyeing effect, but they are not coordinated with the smoke, which brings bad influence on reconstituted tobacco leaves.
[0004] Red sun-cured tobacco is the tobacco leaves produced by sun-cured tobacco using sunlight as a direct heat source to complete the modulation process. It has a bright red color, strong smoke aroma, strong strength, relatively high nicotine content, low sugar and tar content, and has a unique taste and aroma. However, sun-dried red tobacco leaves have disadvantages such as rough smoke, excessive irritation, heavy local miscellaneous gas, poor combustibility, and poor industrial usability of cigarettes.
Starch in sun-cured tobacco leaves has adverse effects on smoke quality, one is the burning speed and completeness of combustion, and the other is burnt smell during burning, which makes the aroma of tobacco worse; the protein in sun-cured tobacco leaves is negatively correlated with tobacco smoking

Embodiment 1

[0022] The invention provides a preparation method of sun-cured red tobacco extract, comprising the following steps:

[0023] (1) Two-step enzymatic aroma enhancement and biotransformation of sun-cured tobacco leaves: the first step is to enzymatically produce aroma, mix sun-cured tobacco leaves and water at a mass ratio of 1:10, and adjust the pH to 4.5 with citric acid. At 45°C, add 0.05% of the mass of tobacco leaves β-glucosidase (enzyme activity 100u / g, food grade), stir evenly, and incubate for 2 hours; in the second step of biotransformation, add the mass of tobacco leaves to the fermentation broth 0.01% protease and cellulase (enzyme activity is 100,000 u / g, mass ratio 1:1, food grade), stir evenly, incubate at 45°C for 2 hours, and inactivate the enzyme at 100°C for 3 minutes;

[0024] (2) Maillard reaction and reflux extraction of sun-cured red tobacco leaves: extract the two-step fermentation liquid in step (1) at 50°C for 2 hours under reflux, filter with suction, ...

Embodiment 2

[0031] The invention provides a preparation method of sun-cured red tobacco extract, comprising the following steps:

[0032] (1) Two-step enzymatic aroma enhancement and biotransformation of sun-cured tobacco leaves: the first step is to enzymatically produce aroma, mix sun-cured tobacco leaves and water at a mass ratio of 1:15, and adjust the pH to 5.0 with citric acid. At 50°C, add 0.1% β-glucosidase (enzyme activity 100u / g, food grade) of the mass of tobacco leaves, stir evenly, and incubate for 2.5 hours; in the second step of biotransformation, add 0.05% β-glucosidase to the above fermentation broth protease and cellulase (enzyme activity is 50,000 u / g, mass ratio 1:1, food grade), stir evenly, incubate at 50°C for 2.5 hours, and inactivate the enzyme at 100°C for 5 minutes;

[0033] (2) Maillard reaction and reflux extraction of sun-cured red tobacco leaves: extract the two-step fermentation liquid in step (1) at 55°C for 3.5 hours under reflux, filter with suction, ret...

Embodiment 3

[0040] The invention provides a preparation method of sun-cured red tobacco extract, comprising the following steps:

[0041] (1) Two-step enzymatic aroma enhancement and biotransformation of sun-cured tobacco leaves: the first step is to enzymatically produce aroma, mix sun-cured tobacco leaves and water at a mass ratio of 1:35, and adjust the pH to 5.5 with citric acid. At 55°C, add 0.25% β-glucosidase (enzyme activity 100u / g, food grade) of the mass of tobacco leaves, stir evenly, and incubate for 4 hours; in the second step of biotransformation, add 0.1% β-glucosidase to the above fermentation broth Protease and cellulase (enzyme activity is 20,000 u / g, mass ratio 1:1, food grade), stir evenly, incubate at 60°C for 4 hours, and inactivate the enzyme at 100°C for 4 minutes;

[0042] (2) Maillard reaction and reflux extraction of sun-cured red tobacco leaves: the two-step fermentation liquid in step (1) was extracted at 60°C for 5 hours under reflux, suction filtered, and th...

Abstract

The invention provides a method for preparing dark sun-cured tobacco extract and application of the method. The method comprises the steps that firstly, dark sun-cured tobacco is subjected to enzymatic aroma enhancement and biotransformation in two steps; aroma enhancement is carried out under the acidic condition through beta-glucosidase biotransformation, and then protease and amylase are added to hydrolyze protein not beneficial to smoking in the dark sun-cured tobacco into free amino acid and decompose starch into glucose and the like; water bath stirring is carried out under the alkaline condition, self free amino acid and revertose serve as a natural nitrogen source and carbon source, a Maillard reaction is carried out, reflux extraction is carried out for 3-5 hours at the temperature of 60 DEG C to 70 DEG C, filtrate is obtained after suction filtration, macroporous resin is used for separation and purification, macromolecular impurities are further removed, and after desorption is carried out, a desorption solution is concentrated to obtain the high-purity dark tenne dark sun-cured tobacco extract. The dark sun-cured tobacco extract is applied to regenerated tobacco, the smoke aroma and strength of the regenerated tobacco can be remarkably improved, irrigation and offensive odors can be reduced, the taste can be improved, and the quality of the regenerated tobacco can be improved.

Description

technical field [0001] The invention relates to the technical field of tobacco additives, in particular to a method for preparing sun-cured red tobacco extract and its application. Background technique [0002] Reconstituted tobacco leaves are mainly composed of tobacco powder, chips, tobacco stems or low-grade tobacco leaves with adhesives and other additives, and there are flavor defects such as heavy miscellaneous gas, strong irritation, and unpleasant taste, which affect its use in cigarette products. quantity. The usual practice in China is to use additives to improve. At present, the most used additives are tobacco and natural plant extracts. These extracts are generally obtained through water, alcohol extraction or molecular distillation. The degree of improvement in cigarette quality after adding Limited, there are still defects such as large irritation and a lot of miscellaneous gas. [0003] In order to make the style of cigar-shaped cigarettes made of reconstitu...
