Description

A kind of cigar tobacco leaf barrel type fermentation method

technical field

The invention relates to a fermentation method of cigar leaves, in particular to a barrel fermentation method of cigar leaves. the

Background technique

Cigars refer to tobacco products that use air-dried tobacco and its regenerated sheets as outer wrappers, and use air-dried tobacco leaves with cigar aroma as the main material of the cigarette core, and the smoke has a significant cigar aroma. The structure of the existing cigar products is core leaf, inner foreskin and outer foreskin successively from inside to outside. Generally, one tobacco plant can produce three types of tobacco leaves: core leaf, inner foreskin and outer foreskin, that is, the top leaf is used as the core leaf, and the middle and lower leaves are used as the foreskin leaf, but usually only one kind of tobacco leaf is more dominant. These three types of tobacco leaves have the basic characteristics of dark air-cured tobacco, but each type has its special requirements for environmental conditions and cultivation techniques. At this stage, the raw materials for the production of cigars in my country are air-cured tobacco, sun-cured red tobacco, burley tobacco and other types of tobacco, mainly sun-cured red tobacco and burley tobacco. the

Existing practice has proved that before making cigarettes, tobacco leaves must be naturally aged, so that its inner fragrance can be fully displayed and brought into play, and the use value will be improved. Among them, the process of natural aging is to make the tobacco leaves naturally mellow through some methods. Specifically, the tobacco leaves are stored in a warehouse with good storage conditions for a certain period of time, and a method of improving the quality of the tobacco leaves is achieved by means of the slow chemical reaction inside the tobacco leaves. However, the time for natural alcoholization is generally longer, usually about 2 years, which not only requires a large amount of storage for alcoholization, but also takes up a lot of funds, and the market response is slow. the

After years of scientific experiments and production practices, practitioners and scientists in the cigar industry have created various methods to accelerate the aging of tobacco leaves, and collectively refer to these methods as tobacco leaf fermentation to distinguish natural aging of tobacco leaves. Fermentation is accelerated aging, and aging is slow fermentation. The functions and principles of the two are the same. Therefore, tobacco leaf fermentation is a primary processing method to improve product quality in the cigar industry, and it is also an extremely important link in cigar processing. Unfermented cigar leaves have a variety of quality defects to varying degrees, such as green miscellaneous and irritating, monotonous aroma, insufficient aroma, etc., and cannot be directly used in the production of cigars. A good fermentation process can improve the quality of cigar leaves and cigar tobacco. the

At this stage, for domestic tobacco leaf raw materials used to produce cigars, there are generally quality defects such as high nicotine content, high strength, strong irritation, and heavy residue. However, traditional fermentation methods cannot solve these problems well. the
