Problems solved by technology

However, when the tobacco leaves are stored in a low-oxygen environment, the polyphenols contained in the tobacco leaves will be oxidized rapidly due to the high oxygen concentration in the normal environment. reaction, causing the color of tobacco leaves to darken rapidly and greatly, which seriously affects the quality of tobacco leaves, especially the appearance quality
This phenomenon of deterioration is especially obvious in summer and autumn, which greatly affects the production of cigarettes in these two quarters

Embodiment 1

[0018] The low-oxygen storage tobacco leaves are stored in a low-temperature environment immediately after unsealing. The low-temperature environment is: 0°C, an oxygen concentration of 21% (that is, the oxygen concentration in normal air), and a humidity of 55%. Gradually increase the temperature in the low-temperature storage room at a rate of 1°C / 24h until the temperature reaches 30°C, and it can be used normally. %, humidity 55% storage room open storage, until the time is 60 days (calculated since the day taken out of the hypoxic environment), to investigate the follow-up effect of the opening method on the appearance of tobacco leaves.

Embodiment 2

[0020] The low-oxygen storage tobacco leaves are stored in a low-temperature environment immediately after unsealing. The low-temperature environment is: 4°C, an oxygen concentration of 21% (that is, the oxygen concentration in normal air), and a humidity of 55%. Gradually increase the temperature in the low-temperature storage room at a rate of 1°C / 24h until the temperature reaches 30°C, and it can be used normally. %, humidity 55% storage room open storage, until the time is 60 days (calculated since the day taken out of the hypoxic environment), to investigate the follow-up effect of the opening method on the appearance of tobacco leaves.

Embodiment 3

[0022] The low-oxygen storage tobacco leaves are stored in a low-temperature environment immediately after unsealing. The low-temperature environment is: 4°C, oxygen concentration 21%, and humidity 65%. Then increase the storage temperature, and gradually increase the temperature in the low-temperature storage room at a rate of 1°C / 24h until the temperature is 30°C, and it can be used normally. In order to reflect the effect of this activation method on storage, after normal use, keep 30°C, 21% oxygen concentration, and 55% humidity were stored open in the storage room until 60 days (calculated since the day it was taken out of the hypoxic environment), and the subsequent effects of the opening method on the appearance of the tobacco leaves were investigated.

Abstract

The invention discloses a method of starting to use tobacco leaves stored in hypoxic environment in summer and autumn in Guangdong Province. The method comprises following steps: S1. unsealing tobacco leaves stored in hypoxic environment in a low-temperature store room/storing the tobacco leaves in the low-temperature store room immediately after unsealing, wherein, the temperature of the low-temperature store room is 0 to 4 DEG C, the oxygen concentration is the normal concentration of the oxygen in the air, and the relative humidity is 55 to 65%; S2. increasing the temperature in the low-temperature store room at a heating rate of 1 to 2 DEG C/24h and the tobacco leaves can be normally used until the temperature is increased by 20 to 35 DEG C. The method of the invention makes the low oxygen stored tobacco leaves have sufficient time to adapt to the external high oxygen concentration environment after opening by controlling the low temperature and relative humidity; the oxidation reaction rate of polyphenols was controlled effectively, and the rapid and large color change of tobacco leaves after being placed in high oxygen concentration environment was avoided successfully. The quality of tobacco leaves, especially the appearance quality, was effectively guaranteed. And after returning to normal environment, even in a certain period of time storage, color will not change significantly.

Description

technical field [0001] The invention belongs to the field of tobacco storage, and in particular relates to a summer and autumn activation method for low-oxygen stored tobacco leaves in Guangdong area. Background technique [0002] Guangdong Province is located in the southeast coastal area, which has the climate characteristics of high temperature and high humidity, which is not conducive to long-term storage of tobacco leaves. Therefore, tobacco companies usually store tobacco leaves in a low-oxygen sealed environment for long-term storage (the oxygen concentration is generally maintained at about 2%) to prevent quality problems such as mildew, insect damage, and excessive moisture in tobacco leaves. However, when the tobacco leaves are stored in a low-oxygen environment, the polyphenols contained in the tobacco leaves will be oxidized rapidly due to the high oxygen concentration in the normal environment. The reaction causes the color of tobacco leaves to turn dark rapidl...
