Embodiment 1

[0021] A method for reducing the content of specific nitrosamines in burley tobacco. The prepared burley tobacco leaves are stored in a constant temperature and humidity storage room. The temperature in the storage room is kept at 10°C. The moisture content of burley tobacco leaves is 7.7%. for 15 days.

Embodiment 2

[0023] Repeat Example 1 with the following differences. The modulated Burley tobacco leaves are placed in a constant temperature and humidity storage room for storage. The temperature in the storage room is maintained at 10° C., the moisture content of the Burley tobacco leaves is 18%, and the storage time is 15 days.

Embodiment 3

[0025] Repeat Example 1 with the following differences. The modulated Burley tobacco leaves are placed in a constant temperature and humidity storage room for storage. The temperature in the storage room is maintained at 10° C., the moisture content of the Burley tobacco leaves is 22.1%, and the storage time is 15 days.

Abstract

The invention relates to a method for reducing the content of specific nitrosamines in burley tobaccos. Blended burley tobacco leaves are stored in a constant-temperature and constant-humidity storage room, wherein the temperature in the storage room is 10 DEG C-30 DEG C and the moisture content of the burley tobacco leaves is 7.7%-22.1%. By regulating and controlling the temperature and humidity of a storage environment, the generation of strong carcinogens TSNA (Tobacco-Specific Nitrosamines) in the storage process is effectively reduced, so that the safety of burley tobacco raw materials is improved and harms to health of smokers, caused by the tobacco leaves, are reduced.

Description

Technical field: [0001] The invention belongs to the technical field of improving tobacco quality and reducing tobacco damage to human health, and in particular relates to a method for reducing the content of specific nitrosamines in burley tobacco. Background technique: [0002] Tobacco-specific nitrosamines (TSNA) mainly include N-nitrosonornicotine (NNN), 4-(N-methyl-nitrosamine)-1-(3-pyridyl)-1-butanone (NNK), N-nitrosoanatabine (NAT) and N-nitroso anatabine (NAB), which have been confirmed to be associated with tumors in the lung, oral cavity, esophagus, pancreas, liver, etc. produce related. [0003] Many studies have shown that there is almost no TSNA in fresh tobacco leaves, and its formation and accumulation are mainly during the conditioning and storage of tobacco. For Burley tobacco, the storage stage of Burley tobacco after conditioning is an important period for the formation of TSNA. Studies have shown that during the storage stage of Burley tobacco, the TSNA...
