Problems solved by technology

At present, the traditional method is to extract the tobacco raw material with a polar solvent and concentrate it into a paste, or to extract the water extract through alcohol precipitation and then take the clear liquid to concentrate to obtain a tobacco paste. The relative content of the aromatizing ingredients contained in the tobacco is not high, the solvent consumption is large and there are problems such as residues, which cannot meet the needs of the further development of the tobacco industry

Embodiment 1

[0016] Take 500g of pulverized Burley tobacco leaves, add 2000mL of 75% ethanol and heat at 80°C for 3h to extract. After filtering, the filtrate is concentrated to remove the solvent. After concentration, the Burley tobacco concentrate is obtained. After adjusting the pH value to 7.0 with sodium hydroxide, add 5.0g / L neutral protease to it and incubate in a water bath at 40°C for 4h, and concentrate to prepare a neutral protease enzymatically hydrolyzed Burley tobacco extract.

[0017] Take the burley tobacco extract and place it in a vacuum distillation equipment. The concentrate is distilled under reduced pressure. The system pressure is 1mmHg. The fraction A below 200°C and the fraction B between 200°C and 300°C are collected. Take 1g of the distillate whose mass ratio is fraction A: fraction B=5:4, dissolve it with 6g propylene glycol, and add it to the electric heating new-type cigarette tobacco products prepared by thin slices, which can reduce the irritation to the throat ...

Embodiment 2

[0019] Take 500g of crushed flue-cured tobacco leaves, add 4000mL of 60% ethanol and heat at 85°C for 4h to extract. After filtering, the filtrate is concentrated to remove the solvent. After concentration, the flue-cured tobacco concentrate is obtained. The flue-cured tobacco extract is adjusted with sodium hydroxide to adjust the pH After the value is 7.0, add 5.0g / L neutral protease to it and incubate in a water bath at 55°C for 4h, and concentrate the flue-cured tobacco extract after enzymolysis with neutral protease.

[0020] Take the flue-cured tobacco extract, place it in a vacuum distillation device, and distill the concentrate under reduced pressure, slowly heating, and the system pressure is 3mmHg, and collect fraction A below 200°C and fraction B at 200°C to 300°C. Take 1 g of the distillate whose mass ratio is fraction A: fraction B=5:7, dissolve it with 7 g of propylene glycol, and add it to the new carbon-heated cigarette tobacco product prepared by the sheet.

Embodiment 3

[0022] Take 500g of pulverized Burley tobacco leaves, add 3000mL of 95% ethanol and heat reflux for 3h at 65°C for extraction. After filtration, the filtrate is concentrated to remove the solvent. After concentration, the Burley tobacco concentrate is obtained. After adjusting the pH value of 7.0 with sodium hydroxide, 5.0g / L neutral protease was added to it and bathed in a water bath at 50°C for 3h, and concentrated to prepare a neutral protease enzymatically hydrolyzed Burley tobacco extract.

[0023] Take the burley tobacco extract and place it in a vacuum distillation equipment. The concentrate is distilled under reduced pressure. The system pressure is 5mmHg. The fraction A below 200°C and the fraction B between 200°C and 300°C are collected. Take 1g of the distillate whose mass ratio is fraction A: fraction B=5:2, dissolve it with 8g propylene glycol, and add it to the electronic cigarette.

[0024] After adding the low-protein tobacco extracts prepared in the foregoing Examp...

Abstract

The invention provides a preparation method for low-protein tobacco extract for novel tobacco and application.Tobacco serves as a raw material, after the tobacco is smashed, ethyl alcohol with the mass fraction of 60%-95% is added according to the material-liquid mass ratio of 1:4 to 1:8, and heating reflux extraction in a water bath is conducted for 2-4 h at the temperature of 65-85 DEG C; filtrate is concentrated after filtering is conducted, a solvent is removed, tobacco concentrate is obtained, the pH value of the tobacco concentrate is adjusted to be 7.0 with sodium hydroxide, neutral protease is added, a water bath is conducted at the temperature of 40-55 DEG C for 3-4 h, and tobacco extract obtained after enzymolysis of neutral protease is prepared after concentration; the tobacco extract is placed in reduced pressure distillation equipment, the concentrate is subjected to reduced pressure distillation and slowly heated, the pressure of a system ranges from 1 mmHg to 5 mmHg, and a fraction A at the temperature of 200 DEG C or below and a fraction B at the temperature of 200-300 DEG C are collected respectively.Protein in the tobacco can be completely removed, and then the tobacco extract with the low protein content and good flavoring effect is obtained.

Description

Technical field [0001] The invention belongs to the technical field of tobacco, and specifically relates to a preparation method and application of a low-protein tobacco extract for novel tobacco. Background technique [0002] In recent years, with the advancement of cigarettes, reducing the tar release of cigarettes has brought insufficient tobacco taste and reduced satisfaction is a problem that the tobacco industry needs to solve urgently. [0003] Tobacco extract is a dark brown viscous paste that can be used in tobacco flavors to increase the natural aroma of tobacco and improve the quality of tobacco smoking. At present, the traditional method is to extract the tobacco raw materials with polar solvents and concentrate them into a paste, or the water extract is treated with alcohol precipitation and then the clear liquid is concentrated to obtain the smoke paste. The smoke paste obtained by similar process extraction is generally of average quality, and there are smoke pastes....
