Problems solved by technology

Conventional methods can improve the maturity of tobacco leaves to a certain extent, improve the taste of tobacco leaves, and remove the miscellaneous gases of tobacco leaves, but the quality of tobacco leaves is not significantly improved, and at the same time, the tobacco leaves after industrial fermentation are still heavy with miscellaneous gases and lack of flavor.
In this method, the fermentation of tobacco leaves mainly uses the substances in tobacco leaves as nutrients to supply tobacco leaves for fermentation. The richness of the products is relatively simple, and the content of aroma components produced is relatively low.
At present, in the field of cigar tobacco leaf fermentation, the method of adding medium fermentation to tobacco leaves is relatively rare, and there are few related reports

Embodiment 1

[0017] Prepare 300g of Dexue No. 1 upper grade 2 cigar leaves, mix 2.5mL of Kvass concentrate and 47.5mL of deionized water to prepare a mixed solution, spray the mixed solution evenly on the surface of the cigar leaves, and then put the leaves into a burlap bag middle. Put the burlap bag into a constant temperature and humidity incubator for fermentation, and the fermentation conditions are as follows: the fermentation humidity is 75%, the temperature is 35°C, and the fermentation period is 30 days. After the fermentation, the moisture balance of the tobacco leaves was carried out until the moisture content of the tobacco leaves was 17±1%, and then the tobacco leaves were rolled into cigarettes, and professional evaluation personnel were organized to conduct sensory evaluation. The results are shown in Table 1.

[0018] In addition, the mixed solution was replaced with pure water, and the blank control group experiment was carried out according to the same procedure.

Abstract

The invention discloses a method for improving tobacco leaf quality by using kvass to ferment tobacco leaves, which comprises the following steps: uniformly mixing a kvass concentrated solution with a solvent according to a certain proportion to obtain a mixed solution for fermentation; preparing different varieties of cigar tobacco leaves in different producing areas, uniformly spraying the mixed solution obtained in the step 1 on the surfaces of the cigar tobacco leaves, then putting the cigar tobacco leaves into a gunny bag, putting the gunny bag into a constant-temperature and constant-humidity incubator, and setting the fermentation humidity to be 65-75%, the temperature to be 30-40 DEG C and the fermentation period to be 30-40 days; and after fermentation is finished, taking out the fermented tobacco leaves and carrying out moisture balance. The cigar tobacco leaves treated by the method provided by the invention have the advantages that the aroma richness is improved, the aroma quality is improved, the sweet feeling is increased, the smoke is fuller and smoother, the aftertaste feeling and the combustion characteristic are improved, the offensive odor and the irritation are weakened, the cigar tobacco leaves have obvious baking aroma, bread aroma and milk aroma, and the aroma enhancement and quality improvement of the cigar tobacco leaves are effectively realized.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a method for improving the quality of tobacco leaves by utilizing Kvass fermented tobacco leaves. Background technique [0002] There are few varieties of high-grade sensory quality of domestic cigar leaves, most of the tobacco leaves have low aroma richness, heavier air, obvious mouth residue and weak sweetness, etc. In order to improve the smoking quality of domestic cigar leaves, cigar factories The physical and chemical properties of tobacco leaves are changed through secondary fermentation technology, thereby improving the aroma and taste of tobacco leaves and reducing irritation and miscellaneous air. [0003] The cigar leaves after agricultural fermentation have problems such as obvious stimulation and insufficient aroma. During the fermentation process of conventional industrial fermented cigar leaves, only water is usually added to increase the moisture conten...
