Problems solved by technology

However, the air-dried tobacco leaves are green and have heavy miscellaneous gas, pungent and irritating taste, resulting in soft smoke, monotonous aroma, and insufficient aroma, which cannot meet the quality requirements for direct use in industrial processing.
It has been reported that air-dried tobacco is used to solve the above problems by microbial fermentation; however, although the use of microbial fermentation to obtain air-dried tobacco reduces the spicy and irritating taste; but the aroma and aroma of the smoke are insufficient, the strength is weak, and the aftertaste is not pure enough; to the quality requirements for industrial processing

Embodiment 1

[0039] (1) After the fresh tobacco leaves are fully aired, turned yellow and fixed, and removed from the shelf, the water content of the tobacco leaves is 10wt%; put into water and soak for 30 minutes;

[0040] (2) The tobacco leaves of step (1) are evenly sprayed with the dry tobacco characteristic extract, and the fermentation time is 2 days at 90° C.; the moisture content of the tobacco leaves during fermentation is 30%;

[0041] (3) drying the tobacco leaves after fermentation for 10 days again, so that the moisture content of the tobacco leaves is 12wt%;

[0042] (4) Put the air-dried tobacco leaves into natural aging for 30 days, the air relative humidity is 50%, and the temperature is 30° C. at room temperature; the air-dried tobacco is obtained.

Abstract

The invention discloses a method for preparing sun-cured tobacco, which comprises the following steps of: (1) sun-curing fresh tobacco leaves, yellowing, fixing color, putting into water, and soaking for a period of time; (2) taking out the soaked tobacco leaves, uniformly spraying a tobacco characteristic extract, and carrying out sealed natural fermentation at a certain temperature for a period of time; (3) airing the fermented tobacco leaves again; and (4) naturally aging and alcoholizing the aired tobacco leaves under a certain condition to obtain the aired tobacco leaves. The sun-cured tobacco obtained by the method disclosed by the invention has flower fragrance, fruit fragrance and rice wine fragrance; the sun-cured tobacco has less offensive odor in smoke, has a ketonic sweet fragrance, and is good in strength and purer in tobacco flavor.

Description

technical field [0001] The invention belongs to the technical field of tobacco fermentation technology, and in particular relates to a technical method for improving the quality of air-cured tobacco by using a characteristic extract of dry tobacco. Background technique [0002] The aroma quantity and aroma quality of tobacco leaves are determined by the components, contents, proportions and interactions of various aroma substances. Aroma substances in tobacco leaves are affected by various factors such as tobacco genotype, ecological environment, cultivation techniques, and conditioning measures. The conditioning process is the process of maximizing the quality potential of tobacco leaves, and plays an important role in the formation of tobacco aroma quality. effect. The study pointed out that the ripening and curing process of tobacco leaves is the main period for the degradation of aroma precursors and the formation and transformation of aroma substances. The tobacco lea...
