Problems solved by technology

Recently, some domestic spice manufacturers and research institutes have successively carried out research and production of tobacco extracts, such as using tobacco raw materials to extract with water, acidifying the extract, distilling and concentrating the extract after acidifying, re-distilling the concentrate to obtain volatile oil, and extracting the concentrate Precipitate with alcohol, add volatile oil after recovering alcohol to get tobacco extract, but, so far, domestic tobacco extract varieties are still relatively small, the quality still needs to be further improved, and the preparation process and equipment used are also more complicated. This hinders the further development of the tobacco industry. For this reason, the industry department urgently hopes that the relevant scientific and technological personnel can provide a cheap, high-quality, simple and easy method to improve and improve the aroma of tobacco extract, so as to promote the technological progress of the tobacco industry.
[0003] During the cigarette production process, the tobacco powder is discarded because the physical indicators do not meet the production and processing requirements, but it still contains some useful ingredients

Embodiment 1

[0026] Referring to Fig. 1, (1) first add water and enzymes to the tobacco powder for enzymolysis: the degree of crushing of tobacco leaves is 40 mesh, the ratio of material to water is 1:4, the enzyme used is cellulase, and the dosage is 2‰ of the quality of tobacco leaves, and the enzymolysis time 14hr, enzymatic hydrolysis temperature 40°C; then add trypsin and acid protease, the dosage is 2‰ of tobacco leaf mass, enzymolysis time 14hr, enzymolysis temperature 40°C.

[0027] (2) Ethanol extraction, filtration and concentration: add absolute ethanol to (1) until the ethanol concentration is 30%, condense the reflux extraction, the extraction time is 4hr, filter after extraction, and filter with a plate and frame filter press, the filtrate After another suction filtration, the insoluble impurities in the extract will be removed; the extract should be concentrated by a thin-film evaporator that can be fed continuously. The evaporation conditions are condensing temperature 10°C ...

Embodiment 2

[0030] Referring to Fig. 1, (1) first add water and enzymes to the tobacco powder for enzymolysis: the degree of crushing of tobacco leaves is 200 mesh, the ratio of material to water is 1:15, the enzyme used is arabinase, and the dosage is 8‰ of the quality of tobacco leaves. The enzymolysis time is 6 hours, the enzymatic hydrolysis temperature is 70°C; then compound protease and trypsin are added, the dosage is 8‰ of the tobacco leaf mass, the enzymolysis time is 6hr, and the enzymolysis temperature is 70°C.

[0031] (2) Ethanol extraction, filtration and concentration: add absolute ethanol to the (1) enzymolysis solution until the ethanol concentration is 75%, reflux extraction in the condenser tube, the extraction time is 1hr, filter after extraction, and the filtrate is suction filtered again, The insoluble impurities in the extract are removed; the extract is concentrated by a thin-film evaporator that can be continuously fed, and the evaporation conditions are a condensa...

Embodiment 3

[0034] Referring to Fig. 1, (1) first add water and enzymes to the tobacco powder for enzymolysis: the degree of crushing of tobacco leaves is 80 mesh, the ratio of material to water is 1:7, the enzyme used is hemicellulase, and the dosage is 4‰ of the quality of tobacco leaves. The enzymolysis time is 12 hours, the enzymatic hydrolysis temperature is 60°C; then alkaline protease and neutral protease are added, the dosages are respectively 4‰ and 5‰ of the mass of tobacco leaves, the enzymolysis time is 10hr, and the enzymolysis temperature is 55°C.

[0035] (2) Ethanol extraction, filtration and concentration: add dehydrated ethanol to (1) until the ethanol concentration is 50%, reflux the condenser tube for extraction, the extraction time is 2hr, filter after extraction, and the filtrate is filtered once again, and the extract The insoluble impurities in the medium are removed; the extract is concentrated by a thin-film evaporator that can be continuously fed, and the evapora...

Abstract

The invention discloses a preparing method for a tobacco-made extract. The invention includes the following steps: tobacco leaves are firstly blended with water and enzyme for enzymolysis; and then ethanol is applied for extraction, filtration and concentration; and lastly the tobacco-made extract is obtained through maillard reaction. The invention utilizes the tobacco dust generated from the tobacco production, takes into full consideration the feasibility and operability of industrial production with respect to the preparing process, and furthermore, conducts a series of exploration on factors relating to the enzymolysis, extraction and maillard reaction forms the final preparing process and optimal technical parameters, and thereby the product quality reaches the requirements for adding fragrance to the tobacco-made extract with outstanding steadiness and repeatability.

Description

technical field [0001] The invention relates to the technical field of tobacco production, in particular to a preparation method of tobacco extract. Background technique [0002] Tobacco extract is a dark brown viscous paste with a characteristic aroma of tobacco. Tobacco extract can be used in tobacco essence to enhance the natural aroma that complements the inherent characteristics of tobacco, and to cover up the local flavor of tobacco leaves in a single area. Recently, some domestic spice manufacturers and research institutes have successively carried out research and production of tobacco extracts, such as using tobacco raw materials to extract with water, acidifying the extract, distilling and concentrating the extract after acidifying, re-distilling the concentrate to obtain volatile oil, and extracting the concentrate Precipitate with alcohol, add volatile oil after recovering alcohol to get tobacco extract, but, so far, domestic tobacco extract varieties are still ...
