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

Example Embodiment

[0025] Example 1

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

[0027] (2) Ethanol extraction, filtration and concentration: Add absolute ethanol to (1) to an ethanol concentration of 30%, reflux extraction with condenser, extraction time 4hr, after extraction, filter, use a plate and frame filter to filter the filtrate Suction filtration is performed again to remove insoluble impurities in the extract; the extract should be concentrated by a thin-film evaporator that can be fed continuously. The evaporation conditions are the condensation temperatu...

[0029] Example 2

[0030] Referring to Figure 1, (1) First, add water and enzymes to the tobacco dust for enzymatic hydrolysis: the pulverization degree 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. Time 6hr, enzymolysis temperature 70℃; then add compound protease and trypsin, the dosage is 8‰ of tobacco leaf mass, enzymolysis time 6hr, enzymolysis temperature 70℃.

[0031] (2) Ethanol extraction, filtration and concentration: Add absolute ethanol to (1) Enzymatic hydrolysis solution to an ethanol concentration of 75%, reflux extraction with a condenser, extraction time 1hr, after extraction, filter, and filter the filtrate once more. The insoluble impurities in the extract are removed; the extract is concentrated by a thin-film evaporator that can be fed continuously. The evaporation conditions are 2°C for condensation and 80°C for heating. After repeated concentration, t...

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 ...
