However, because the existing fermentation and alcoholization process is mostly based on the research of flue-cured tobacco leaves, and the raw materials of cigar tobacco leaves are not consistent with those of flue-cured tobacco leaves in terms of nitrogen content and sugar content, so the strains and fermentation treatment processes of flue-cured tobacco leaves are different. It must be suitable for the use of cigar tobacco leaves. In other words, in order to better improve the smoking quality of cigar tobacco, the fermentation treatment process of cigar tobacco leaves needs to be re-explored and designed

Embodiment 1
[0041] Taking some cigars (the upper part of the filler tobacco leaves of the second grade) as an example, the specific fermentation treatment was carried out. The specific process is as follows.
[0042] (1) Screening and selection of microbial flora during tea fermentation
[0043]The types of microbial strains used in this example are Penicillium: Mucor: Aspergillus niger: Rhizopus: yeast=2:2:1:1:1.
[0044] (2) Preparation of seed liquid by fermentation
[0045] The mixture of tea leaves, tobacco powder, and sodium chloride with water is used as the seed medium, and the seed medium contains 5g of tobacco powder and 0.8g of sodium chloride per 100mL of water;
[0046] The tea leaves are Pu'er tea leaves; for the convenience of subsequent fermentation treatment, the tea leaves are pulverized and passed through a 200-mesh sieve;
[0047] The tobacco powder is flue-cured tobacco powder; for the convenience of subsequent fermentation treatment, the tobacco powder is pulverize...
Embodiment 2
[0056] The fermentation treatment process of this implementation is the same as that of Example 1, only the type of microbial strains in step (1) is adjusted, Penicillium: Aspergillus niger: Yeast = 4:2:1.
[0057] The cigar tobacco leaf prepared in this embodiment is sampled, and the sample is marked as 2#.
Embodiment 3
[0059] The fermentation treatment process in this implementation is the same as in Example 1, only the type of microbial strains in step (1) is adjusted to be Penicillium:yeast=2:1.
[0060] The cigar tobacco leaves prepared in this example were sampled, and the samples were marked as 3#, and the naturally alcoholized tobacco leaves without artificial fermentation treatment were marked as CK2.

Abstract
The invention belongs to the technical field of cigar tobacco processing, and particularly relates to a method of using microbial flora for fermenting cigar tobacco leaves. According to the method, the natural microbial flora which is harmless to the human body is adopted to ferment the cigar tobacco leaves; particularly, strains of the microbial flora include yeast and also include a mixture composed of one or more of penicillium, aspergillus niger, mucor and rhizopus according to an arbitrary proportion. Preliminary application effects show that after the cigar tobacco leaves are fermented by the microbial strains coming from tea, the sugar-nitrogen ratio of the cigar tobacco leaves is balanced; the defects of pungency, bitterness, astringency and the like which are caused by acid-base imbalance during combustion and smoking are effectively overcome, the defects of green and versicolor tobacco leaves, irritation and the like are also overcome, transformation of substances related tothe smoking taste of the tobacco and formation of a sweet flower fragrance are promoted, the quality of the fragrance of the tobacco leaves is effectively improved, the amount of the fragrance of thetobacco leaves is effectively increased, and the combustion and smoking quality of the tobacco leaves and the industrial applicability of the cigar tobacco leaves are improved.
Description
technical field [0001] The invention belongs to the technical field of cigar tobacco processing, and in particular relates to a method for fermenting and treating cigar tobacco leaves by microbial flora. Background technique [0002] In the production process of cigar cigarettes, the fermentation and alcoholization of tobacco leaves is an important process in the production and processing of cigarettes. It is generally divided into two methods: natural alcoholization and artificial fermentation. Among them, natural aging is a natural fermentation process using the bacteria contained in the tobacco leaf itself under low temperature and low moisture conditions. The fermentation period is relatively long, generally about 1 to 3 years. This method is suitable for the aging of tobacco leaves for cigar wrappers. Artificial fermentation is a short-term fermentation method carried out under high temperature and high humidity conditions. It aims to eliminate miscellaneous gases, redu...
