preparation example Construction

[0022] The present invention provides a kind of preparation method of modified tobacco extract, comprising the following steps:

[0023] (1) Subcritical extraction: Precisely weigh 1KG of crushed tobacco leaf powder (equivalent to 1 / 30 of the volume of the extraction column), put it into an extraction column of about 1.0 mL, put the extraction column into a constant temperature box, and use an infusion pump to Pump the mixed extractant in constant pressure mode, under the conditions of temperature at 120°C, 140°C, 160°C, 180°C, 200°C, 220°C and pressure at 5, 7, 11, 13, 15, 17 and 19MPa Extract to obtain tobacco volatile aroma substance A and tobacco extract B.

[0024] (2) Organic extraction and concentration: Add absolute ethanol to the tobacco extract B, and reflux the condenser tube for extraction. The extraction time is 4hr. After extraction, the extract is concentrated again with a thin film evaporator that can continuously feed, and the evaporation condition is The con...

Embodiment 1

[0028] Crush the tobacco fragments to 50-100 mesh, accurately weigh 1Kg of tobacco leaf powder, put it into an extraction column, put the extraction column into a constant temperature box, and add 4Kg of extractant water with an infusion pump in constant pressure mode. Extract at 120°C and 5MPa pressure. Tobacco volatile aroma substance A and extract B were obtained.

[0029] Organic extraction and concentration: Add absolute ethanol to the extract B until the ethanol concentration is 30%, reflux extraction in the condenser tube, the extraction time is 4hr, after extraction, the extract is concentrated with a thin film evaporator that can be continuously fed, evaporated The condition is that the condensation temperature is 10°C and the heating temperature is 45°C. After repeated concentration, the extract can be concentrated to a target concentration of 35%.

[0030] Biochemical reaction: Weigh 20g of the concentrated extract, add 40g of high fructose syrup, 10g of glucose sy...

Embodiment 2

[0033] Crush the tobacco fragments to 50-100 mesh, accurately weigh 1Kg of tobacco leaf powder, put it into an extraction column, put the extraction column into a constant temperature box, and add 4kg of extractant water with an infusion pump in a constant pressure mode. Extract at 220°C and 19MPa pressure. Tobacco volatile aroma substance A and extract B were obtained.

[0034] Organic extraction and concentration: Add absolute ethanol to the extract B until the ethanol concentration is 50%, and reflux the condenser tube for extraction. The extraction time is 2.5hr. The condition is that the condensation temperature is 10°C and the heating temperature is 45°C. After repeated concentration, the extract can be concentrated to a target concentration of 35%.

[0035] Biochemical reaction: Weigh 20g of extract, 30g of high fructose syrup, 20g of Umle extract, 20g of propylene glycol, and 10g of water; heat to 115°C; stir and react for 2 hours; reaction.

[0036] The modified to...

Abstract

The invention discloses a preparation method of modified tobacco extracts and particularly discloses a preparation method of natural cigarette flavor. Tobacco fragment waste in tobacco production serves as main raw materials to produce the cigarette flavor, and the modified tobacco extracts are obtained by means of treatment including subcritical extraction, solvent extraction and concentration, natural adjuvant biochemical reaction, blending and the like. By the preparation method, feasibility and operability of industrial production are fully considered, factors involved in an experimental process are studied one by one, and the preparation process and optimal technical parameters are determined finally, so that the product quality reaches the objective demands on flavor enhancement and taste improvement, and the interior quality of cigarettes can be improved remarkably.

Description

technical field [0001] The invention relates to a preparation method of a modified tobacco extract, in particular to the preparation of a natural tobacco spice. It belongs to the technical field of tobacco production. Background technique [0002] At present, the issue of "smoking and health" is attracting more and more people's attention, and the world's cigarette industry is under the increasingly severe pressure of public opinion on smoking and health. Improving the safety of smoking has gradually become a common goal for the tobacco industry to continue to survive and develop. Judging from the development trend of global cigarette consumption, all countries have turned to low-tar products. But, along with the reduction of the amount of tar in cigarettes, the problem that the tobacco industry must solve at first is exactly to make cigarettes still can keep enough smoke fragrance after reducing tar. [0003] In recent years, while cigarette factories have carefully formu...
