Problems solved by technology

[0004] 1. Since the air-curing method is to make the tobacco leaves turn yellow, brown, and dry during the continuous dehydration and drying process of the tobacco leaves, the transformation of the chemical components of the tobacco leaves is insufficient, especially the aroma transformation is insufficient, and the smoking quality of the tobacco leaves needs to be improved;
[0005] 2. Due to the insufficient transformation of ingredients during the preparation process, the smoke of air-dried tobacco leaves is rough and the aroma is not mellow. It must undergo 1-2 months of artificial fermentation or 2-3 years of natural alcoholization before it can be used in cigarette formulations;
[0006] 3. The drying cycle is longer;
[0007] 4. The aroma and flavor type of air-dried tobacco leaves are single, and it is impossible to prepare special-flavor tobacco leaves;
[0008] 5. Field tobacco waste such as cigarette tops and branches cannot be used
[0009] So far, there has been no report on the modulation of air-dried tobacco harvested in the field by fermentation technology.

Embodiment 1

[0049]During the topping stage of field tobacco plants, the underripe leg leaves of Burley tobacco are harvested. These leg leaves are usually knocked out and discarded under conventional technical conditions. In the thermal insulation foam plastic box, cover the case cover after filling it up, place the smoke box in a solar greenhouse for accumulation and fermentation; the inside length, width and height of the foam plastic box are 60cm×60cm×60cm, and the wall thickness is 3cm; There are several evenly distributed air holes with a diameter of about 0.5 cm on the four sides of the box close to the bottom of the box. There is an air hole with a diameter of about 3 cm on the upper side of one end of the box close to the top of the cover; Take 20 smoke boxes as a group, put 4 groups of smoke boxes side by side in two rows of double layers, the distance between the two rows is about 5cm, and the vents are facing the outside to facilitate operation, forming a stack of 80 smoke boxes...

Embodiment 2

[0057] Harvest the top tobacco leaves of field air-drying tobacco, cut off the 1 / 3 part of the leaf tip from the petiole end of the tobacco leaves, and spray the liquid compound enzyme preparation on the leaves at a dosage of 0.5%, and then stack the tobacco leaves evenly in the mesh basket. The length, width, and height of the cigarette baskets are 80cm×55cm×50cm. 25 cigarette baskets are used as a group, and the two groups of cigarette baskets are placed side by side in two rows. The distance between the two rows is about 10cm, and the composition is composed of 50 cigarette baskets. 700-800kg of fresh tobacco leaves can be fermented at one time. The baskets are covered with plastic film for heat preservation and placed in a plastic greenhouse. The fermentation process conditions are as follows:

[0058] Fermentation heating stage: After 2 days of heat preservation and fermentation, the temperature of the tobacco pile is raised from the ambient temperature to 37°C by using th...

Embodiment 3

[0064] Collect the cigarette tops produced during the topping of air-dried tobacco plants, spray the compound fermentation bacteria agent at a dosage of 2.0%, and evenly stack them on the ground. Lay linen mats on the ground in advance to form a long smoke ridge with a width of 2.0m and a height of 40cm. , the surface of the smoke pile is covered with plastic film; the smoke pile is set in a plastic greenhouse, and the fermentation process conditions are:

[0065] Fermentation temperature rise stage: After 2 days of heat preservation and fermentation, the temperature of the smoke stack is raised from the ambient temperature to 38°C by using the heat generated by the fermentation of the top of the cigarette;

[0066] Fermentation and yellowing stage: properly uncover the plastic film, ventilate and dehumidify, control the temperature of the smoke pile at 32-40°C, turn the smoke pile every 2 days, and the degree of yellowing of the smoke top will reach about 80% after 8 days;

Abstract

The invention provides a new curing method for air-cured tobacco, a tobacco leaf product and a purpose. The curing process comprises the following steps of harvesting of field tobacco leaves, stacking and fermentation, dewatering and drying, and the like. The method has the advantages that the ''fermentation curing type'' tobacco leaf product with pure and mild air-cured tobacco fragrance or with air-cured tobacco and fire-cured tobacco fragrance can be cured; by adjusting the fermentation process conditions, the chemical characteristic and the quality characteristic of the cured tobacco leaf product are reasonably adjusted and controlled, the content of nicotine and the content of smoke tar of the upper tobacco leaves are effectively reduced, and the availability of the upper leaves is improved; the field wastes, such as air-cured tobacco leftovers, top leaves, abnormal matured tobacco leaves, tobacco branches and tobacco tops, can be utilized; the cured tobacco leaf product can be used for preparing tobacco leaf formula products or cigarette products, or preparing tobacco extracts and tobacco reaction flavors, and can be used as a material liquid to be added into the tobacco sheets, stem products or cigarette products.

Description

technical field [0001] The invention relates to the technical field of tobacco preparation and processing, in particular to a new method for preparation of field air-dried tobacco leaves, tobacco leaf products and uses. Background technique [0002] The conventional preparation method of air-dried tobacco is to hang the air-dried tobacco leaves harvested in the field in a shed or air-drying room for air-curing and drying, such as Burley tobacco, Maryland tobacco and local air-curing tobacco, etc. The air-curing process generally includes changing During the yellowing period, browning period and tendon drying period, the temperature is 20-35°C, and the conditioning time is 20-40 days. [0003] Adopt the conventional modulation method of airing tobacco to modulate tobacco leaf and mainly have the following deficiencies: [0004] 1. Since the air-curing method is to make the tobacco leaves turn yellow, brown, and dry during the continuous dehydration and drying process of the ...
