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, heat and reflux at 80°C for 3h for extraction, filter and concentrate the filtrate to remove the solvent, obtain the Burley tobacco concentrate after concentration, and extract the Burley tobacco After adjusting the pH value to 7.0 with sodium hydroxide, 5.0 g / L neutral protease was added thereto and kept in a water bath at 40° C. for 4 hours. After concentration, the Burley tobacco extract after enzymatic hydrolysis by neutral protease was obtained.

[0017] Take burley tobacco extract, place it in a vacuum distillation equipment, carry out vacuum distillation on the concentrate, heat slowly, the system pressure is 1mmHg, collect fraction A below 200°C and fraction B between 200°C and 300°C respectively. Take 1 g of the distillate with a mass ratio of fraction A: fraction B = 5:4, dissolve it with 6 g of propylene glycol, and add it to the electric heating new cigarette tobacco product prepared by...

Embodiment 2

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

[0020] Take the flue-cured tobacco extract, place it in a vacuum distillation equipment, carry out vacuum distillation on the concentrate, slowly heat it, the system pressure is 3mmHg, and collect fraction A below 200°C and fraction B between 200°C and 300°C respectively. 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 carbon-heated novel cigarette tobacco product prepared by...

Embodiment 3

[0022] Take 500g of pulverized Burley tobacco leaves, add 3000mL of 95% ethanol, heat and reflux at 65°C for 3h for extraction, filter and concentrate the filtrate to remove the solvent, obtain the Burley tobacco concentrate after concentration, and extract the Burley tobacco After adjusting the pH value to 7.0 with sodium hydroxide, 5.0 g / L neutral protease was added thereto and kept in a water bath at 50° C. for 3 hours. After concentration, Burley tobacco extract after enzymatic hydrolysis by neutral protease was obtained.

[0023] Take the burley tobacco extract, place it in a vacuum distillation equipment, carry out vacuum distillation on the concentrate, heat slowly, the system pressure is 5mmHg, collect fraction A below 200°C and fraction B between 200°C and 300°C respectively. Take 1 g of the distillate whose mass ratio is Fraction A: Fraction B = 5:2, dissolve it with 8 g of propylene glycol, and add it to the electronic cigarette.

[0024] After adding the low-protei...

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 in particular relates to a preparation method and application of a low-protein tobacco extract used in new types of tobacco. Background technique [0002] In recent years, with the promotion of the level of cigarettes, reducing the tar release of cigarettes, the lack of taste of tobacco and the weakening of satisfaction are problems that the tobacco industry needs to solve urgently. [0003] Tobacco extract is a dark brown viscous paste, which can be used in tobacco essence to increase the natural aroma of tobacco and improve the smoking quality of tobacco. 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 components contained in the tobacco i...
