Problems solved by technology

The traditional tobacco leaf extract is mainly to extract the tobacco leaves or shredded tobacco with ethanol or water at low temperature. After some macromolecular substances in the obtained tobacco extract are heated and atomized, there will be black residues on the electronic cigarette atomizer, and they will be smoked again. When heated, these black residues will have a burnt smell, which will affect the taste of the next puff

Embodiment 1

[0022] The present invention provides a kind of preparation method of low order tobacco leaf fermentation extract, comprises the following steps:

[0023] (1) Fermentation transformation of low-grade tobacco leaves: Mix low-grade tobacco leaves and water evenly at a mass ratio of 1:10, adjust the pH to 4.5 with acetic acid, and add 0.05% β- Glucosidase, stirred evenly, incubated for 12 hours to obtain tobacco biotransformation liquid;

[0024] The β-glucosidase is food grade, and the enzyme activity is 10,000 u / g.

[0025] (2) Tobacco Maillard reaction: Add 0.1% aspartic acid and 0.05% xylose, which account for the quality of low-grade tobacco leaves, and stir evenly, adjust the pH to 11 with sodium hydroxide, and pressurize the container to 0.05 MPa at 120°C. Inactivation, Maillard reaction for 3 hours to obtain natural tobacco Maillard reaction mixture;

[0026] The aspartic acid and xylose are food grade.

[0027] (3) Purification by molecular distillation: the natural t...

Embodiment 2

[0031] The present invention provides a kind of preparation method of low order tobacco leaf fermentation extract, comprises the following steps:

[0032] (1) Fermentation transformation of low-grade tobacco leaves: Mix low-grade tobacco leaves and water evenly at a mass ratio of 1:15, adjust the pH to 5.0 with acetic acid, and add 0.1% β- Glucosidase, stirred evenly, incubated for 24 hours to obtain tobacco biotransformation liquid;

[0033] The β-glucosidase is food grade, and the enzyme activity is 1000u / g.

[0034] (2) Tobacco Maillard reaction: Add 0.5% alanine and 0.05% glucose and stir evenly, and adjust the pH to 12 with sodium hydroxide. At 150° C., the pressure in the container reaches 0.07 MPa, and the enzyme is extinguished. Live, Maillard reaction 4 hours, obtain natural tobacco Maillard reaction mixture;

[0035] Both the alanine and glucose are food grade.

Abstract

The invention provides a preparation method and an application of a discarded tobacco leaf fermentation extract. Discarded tobacco leaves are fermented with beta-glucosidase, a tobacco biotransformation liquid containing various increased small-molecular aroma substances is obtained through enzymatic curing, then amino acid and reducing sugar in certain proportion are added for a high-temperature Maillard reaction under an alkaline condition, a natural tobacco Maillard reaction liquid is obtained and subjected to pumping filtration, a filtrate and filter residues are obtained, the filtrate is concentrated and mixed with propylene glycol and the like, further separation and purification are performed through molecular distillation, and light components are collected and taken as the discarded tobacco leaf fermentation extract. Reconstituted tobacco substrates with low irritation, low miscellaneous gas, low nicotine content and low harm are prepared from the filter residues with a paper-making process, the quality of the thin discarded tobacco leaf substrates is improved, the use effect of the discarded tobacco leaves on cigarette products is improved, the adding quantity of the extract is increased, the extract can be applied to an atomization filler material for novel carbon heating tobacco, and the quality of the atomization filler material is improved.

Description

technical field [0001] The invention relates to the technical field of tobacco product additives and reconstituted tobacco leaves, in particular to a preparation method and application of a low-grade tobacco leaf fermentation extract. Background technique [0002] As people pay more attention to health, they also pay more attention to the harm of cigarettes. Surveys in the United States in recent years show that the consumption of cigarettes in the United States is declining year by year, while the consumption of smokeless tobacco products is going against the wind. Since 2001 , continued to grow at a rate of 6% for five consecutive years. In 2007, the consumption of cigarettes in the United States fell by 4% year-on-year, while the consumption of smokeless tobacco increased by 7.1% year-on-year. The world's major cigarette companies have entered the field of smokeless tobacco one after another. The development prospect of smokeless tobacco is broad, the consumption trend h...
