Problems solved by technology

The quality of natural aging tobacco leaves is obviously better than that of artificial aging, and the process is simple and easy to operate. However, the storage period of tobacco leaves is long (generally 2 to 3 years), the optimal aging cycle of tobacco leaves of different origin grades is inconsistent, and tobacco leaf aging takes up a large warehouse. Defects such as a large backlog of funds limit the scale and application range of natural aging

Embodiment 1

[0032] The composite preparation for accelerating the alcoholization of tobacco leaves provided in this example includes microbial preparations and biological enzymes;

[0033] The microbial preparation includes two kinds of Bacillus subtilis bacterial liquid and Sphingomonas bacterial liquid;

[0034] The Bacillus subtilis bacterial liquid is prepared as follows: take Bacillus subtilis strain xp (the preservation number of the China Type Culture Collection Center is: CCTCCNo: M2011452), LB liquid medium, 30 ° C, 200 rpm shaker Cultivate and amplify, use the sterile culture solution as the blank control, record the absorbance value OD at 600nm of the bacterial solution 600 , when OD 600 =6.0, as the application of bacterial liquid; at this time, the number of bacterial cells in the bacterial liquid is roughly 6 billion / mL;

[0035] The sphingomonas bacterial liquid is prepared as follows: take sphingomonas strain xp (the preservation number of the China Center for Typical Cu...

Embodiment 2

[0046] Taking the compound preparation for accelerating the alcoholization of tobacco leaves prepared in Example 1 (Bacillus subtilis bacterial liquid: Sphingomonas bacterial liquid: biological enzyme = 0.7:0.8:0.7) as an example, when it is used for tobacco leaf treatment, The specific process is as follows:

[0047] Take the fresh tobacco leaves after initial roasting (Luzhou-flavor tobacco leaves B2F, the same as Comparative Example 1), and spray the uniformly mixed compound preparation on the surface of the tobacco leaves by spraying, and the spraying amount is 2.2% of the mass of the tobacco leaves; It is directly threshed and re-roasted, then stored in storage, and alcoholized under natural conditions.

[0048] The sensory evaluation and measurement results for tobacco leaves in different periods are as follows:

[0049] Tobacco leaves after threshing and rebaking: the sensory quality score is 60.25 points, the starch content in the tobacco leaves is 5.80%, the protein ...

Embodiment 3

[0054] Taking the compound preparation for accelerating the alcoholization of tobacco leaves prepared in Example 1 (Bacillus subtilis bacterial liquid: Sphingomonas bacterial liquid: biological enzyme = 0.7:0.8:0.7) as an example, when it is used for tobacco leaf treatment, The specific process is as follows:

[0055] Take the fresh tobacco leaves after initial roasting (Luzhou-flavor tobacco leaves B2F, the same as Comparative Example 1), and spray the uniformly mixed compound preparation on the surface of the tobacco leaves by spraying, and the spraying amount is 2.2% of the mass of the tobacco leaves; Store under natural conditions for 30 days (compared with Example 2, increase the treatment of storing under natural conditions for 30 days), then threshing and re-roasting, storage, and alcoholization under natural conditions.

[0056] The sensory evaluation and measurement results for tobacco leaves in different periods are as follows:

[0057] Tobacco leaves after threshin...

Abstract

The invention belongs to the technical field of tobacco processing and particularly relates to a composite preparation for accelerating tobacco mellowing. The composite preparation is prepared from microbial preparations and biological enzymes, wherein the microbial preparations comprise a bacillus subtilis solution and a sphingosine monoucleosis solution. The composite preparation is applied to tobacco treatment in steps as follows: fresh tobacco baked primarily is taken, the uniformly mixed composite preparation is sprayed to the surface of the tobacco uniformly, and the amount of the sprayed composite preparation does not exceed 5% of the mass of the tobacco and is most preferably 2.2%-2.8%; the tobacco with the composite preparation is stored under natural conditions, then threshed, re-dried, put into storage and mellowed under natural conditions and can be used for actual production and preparation of cigarettes after mellowing for 12-20 months. The composite preparation can better simulate the fermentation and mellowing effect under natural conditions after being applied to tobacco treatment, can accelerate tobacco mellowing and shorten the mellowing cycle and has important application value for tobacco enterprises.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a compound preparation for accelerating the aging of tobacco leaves. Background technique [0002] Tobacco leaf aging is a key processing link to improve the sensory quality of tobacco leaves. After the tobacco leaves are harvested, threshed and re-roasted, it usually takes two to three years of aging cycle to achieve the best application quality. Improving the intrinsic quality of tobacco leaves and improving the industrial usability of tobacco through alcoholization has always been one of the hotspots in tobacco research. [0003] According to different aging conditions and methods, tobacco leaf aging technology is divided into natural aging and artificial aging. Natural aging is to store tobacco leaves at room temperature in the warehouse for a period of time, and use natural conditions to make tobacco leaves more suitable for smoking. Artificial alcoh...
