A preparation method of air-drying tobacco, tobacco leaf product and application

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 preparation method 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 tobacco ...

AI Technical Summary

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.
