Method for promote green of tobacco by fermentation

Tobacco fermentation alcoholization methods: artificial alcoholization, natural alcoholization, etc. The modulated raw tobacco is packaged and stored in characteristic places under natural climate conditions for alcoholization 1 ~ 3 years. With the change of season and environment, the internal composition of tobacco leaves changes, the advantages of quality appear, and the quality will gradually improve. This process is called tobacco natural alcoholization. Natural alcoholization, also known as "natural fermentation" and "aging", is a slow fermentation method.

Alcoholism time

Generally, the aging time of tobacco leaves varies according to the specific situation. Tobacco leaves with more resin and better texture have shorter aging time, while tobacco leaves with less resin and thinner texture have longer aging time. The aging time is also related to the ambient temperature. In areas with high annual temperature, the aging time of tobacco leaves is relatively short. For example, in the United States, in order to shorten the aging cycle, cigarette factories in the north usually put tobacco leaves in the south where the temperature is higher.

Aging time is also related to the moisture content of tobacco leaves. The higher the moisture content, the faster the aging fermentation, but the higher the moisture content may lead to mildew during storage. The suitable moisture content for natural aging of tobacco leaves is 10% ~ 13%. Therefore, in the process of natural alcoholization, environmental temperature and humidity conditions are very important factors, and the temperature is preferably about 20℃ and the relative humidity is about 60% ~ 65%.

After storage, the cyan of tobacco leaves decreased, the color of leaves became darker and the color became uniform. In the process of natural alcoholization, attention should be paid to prevent mildew, tobacco pests and burning. In the process of natural alcoholization, tobacco leaves undergo a series of physical and chemical changes with the change of environment, and the effect of improving the quality of tobacco leaves is obviously better than that of artificial fermentation.

Natural alcoholization is also very beneficial to ensure the stability of cigarette quality. Natural alcoholized tobacco leaves are generally used in cigarette production in developed countries. General tobacco factories reserve enough tobacco leaves for cigarette production for 2 ~ 3 years and replenish them every year. Sufficient storage of tobacco leaves ensures the stability of cigarette leaf group formula. So as to ensure the stability of the quality and style of cigarettes, especially famous brands, and win more and more consumers and occupy the market for a long time.
