Tobacco aging is an important process for improving the smoking quality of tobacco and is a complex physiological, biochemical and chemical reaction process accompanied with physical change. In this process, there is a concomitant decrease in the weight of dry matter and the generation of a large amount of gas such as carbon dioxide. Macromolecular organic substances and chemical components in the tobacco leaves are continuously decomposed, converted and consumed under the action of oxidation reaction and enzymatic reaction, and micromolecular organic substances are continuously formed, so that the change of the quality of aroma and taste is promoted. The aged tobacco leaves are orange and oil-wet in color, sufficient in fragrance, obviously reduced in miscellaneous gas and stimulation, mellow in absorbed taste, clean in aftertaste, exposed in stale gas and good in sensory quality.

Selecting tobacco leaves in a Yunnan producing area, classifying according to the upper, middle and lower parts, meanwhile, selecting tobacco leaves in a United states producing area in a targeted manner, and carrying out a fermentation test together.
The two fermentation chamber parameters were set as follows:
fermentation 1 Chamber parameter settings
Fermentation Chamber 2 parameter settings
The moisture content is one of the important components of the tobacco leaves and the products thereof, and the content is high or low, thereby having important influence on the processing performance of the tobacco leaves and the quality of the products thereof. The tobacco leaves are dark in color and luster due to overhigh moisture, and the interaction and consumption of chemical components in the tobacco leaves are accelerated; too low water content can not accelerate tobacco mellowing. Therefore, the selection of proper raw material moisture and the enhancement of the moisture control in the fermentation process have important influence on the fermentation effect of the tobacco leaves.
The tobacco leaves contain colloidal substances such as pectin, cellulose and protein, and crystal substances such as water-soluble sugar and organic acid salts, and the tobacco leaves have the characteristics of moisture absorption and moisture desorption due to the action of the substances. The sample in the fermentation chamber 1 and the sample in the fermentation chamber 2 have the same water change rule in the heat preservation period (after the temperature rise is finished and the temperature is preserved for 10 days), are the moisture desorption and moisture absorption processes, and reach the lowest water point in the heat preservation period on the heat preservation day 2.
Moisture status list
The following table shows: the sensory quality of the sample is better in the fermentation 1 room at the heat preservation day 10; the fermentation chamber 2 has good organoleptic quality at the heat preservation day 6.
Sensory evaluation result of sample of Yunnan Tengchong B2F 2014
The following table shows: the sensory quality of the sample is better in the fermentation 1 room at the heat preservation day 8; the fermentation chamber 2 has good organoleptic quality at the heat preservation day 6.
Sensory evaluation result of sample of' Yunnan Baoshan KC3F 2014
The following table shows: the sensory quality of the sample is better in the fermentation 1 room at the heat preservation day 4-8; the fermentation chamber 2 has good organoleptic quality at the heat preservation day 4.
Sensory evaluation result of sample of' Yunnan Baoshan KX2F 2014
The following table shows: after fermentation, no sample with better sensory quality than the raw material appeared.
Sensory evaluation result of sample of' American CL 12013 years
The American CL1 sample has no appearance of samples with sensory quality exceeding that of raw tobacco in the whole fermentation process, and does not exclude the factor of longer natural alcoholization time of the raw material.
The Yunnan Tengchong B2F sample has the best overall sensory quality on the 5 th heat preservation day, and the specific expression is as follows: the smoke is smooth and harmonious, the aroma is rich, the aroma amount is rich, the stimulation is less, and the miscellaneous gas is less.
The Yunnan Baoshan KC3F sample has the best overall sensory quality on the 5 th day of heat preservation, and the specific expression is as follows: easy, comfortable and harmonious.
The Yunnan Baoshan KX2F sample has the best overall sensory quality on the 3 rd day of heat preservation, and the specific expression is as follows: has good fragrance, moistening feeling, clean aftertaste, less miscellaneous odor and good softness.
The fermentation conditions can be preset as follows:
fermentation conditions of upper and middle leaves
Lower leaf fermentation conditions
The conclusion is as follows:
after several experiments, the upper and middle cigarettes reach the best overall sensory quality on the 5 th day of heat preservation, and the lower cigarettes are advanced to the 3 rd day of heat preservation. The phenomenon has a close relation with the raw material part, the identity of the lower smoke is thin, the accumulation of dry matters and the like is less, and the time required by fermentation is relatively short; the middle and upper leaves have relatively long fermentation time due to the fact that the identity is thick, dry matters and the like are accumulated more. The test results are consistent with theory.
Therefore, the sample is artificially fermented, the natural alcoholization time is short, and the overall quality is improved. Ambient temperature 50.0 ℃/humidity 55.0%: the heat preservation time of the tobacco leaves at different parts is different, and the heat preservation time of the upper leaves and the middle leaves is 5 days, so that the sensory quality is optimal; the lower leaves are kept warm for 3 days, and the sensory quality is optimal.
