Abstract:

In this paper, the main physiological and biochemical change periods of inclusions and the change results in the process of air-curing tobacco modulation were discussed, the modulation techniques of two main types of tobacco (burley and cigar) were summarized, and various simple and convenient temperature and humidity control techniques applied in the process were summed up. It is concluded that most of the studies on the air-curing of tobacco have focused on burley tobacco, while only a few studies have focused on cigar tobacco, mainly on the changes of inclusions and the effects of curing methods and control techniques on the quality of tobacco leaves. In the future, it is necessary to further analyze the transformation mechanism of inclusions during cigar air-curing modulation, as well as the ultrastructural changes of cell tissues and the evolution and function of microbiota, optimize the modulation process, and formulate the standards of cigar air-curing.

Key words: air-curing tobacco, modulation, temperature and humidity, physiology and biochemistry, control technology
