Abstract
The invention relates to a method for reducing N-amine nitrite (TSNA) of cigarette, wherein when the water content of cigarette leaf is under at 40-50%, using microwave at 2450MHz to radiate the leaf for 90s, to kill microbes and reduce the N-amine nitrite.
Description
Affiliated technical field
Patent of the present invention is the method for a kind of reduction tobacco N-unique nitrosamine (TSNA), and this method can effectively reduce the generation of strong carcinogen tobacco N-unique nitrosamine (TSNA), thereby reduces the harm of tobacco to smoker's health.
Background technology
At present, there are more than ten hundred million people's smokings in the whole world, multiple harmful components are arranged in the tobacco, and wherein tobacco N-unique nitrosamine (TSNA) has been identified relevantly with the generation of position tumours such as lung, oral cavity, esophagus, pancreas, liver, and its direct precursor is alkaloid and nitrite.Generally believe at present in fresh tobacco leaf, to have TSNA hardly, but contain TSNA in the tobacco leaf after the modulation, illustrate that TSNA produces between modulation period after gathering.The formation approach of TSNA mainly contains two: nitrosification takes place and generates TSNA in first nicotiana alkaloids under action of microorganisms, it two is that nitrate generates nitrite under action of microorganisms, and these nitrite and other nitrogen oxide generate TSNA with the biological tobacco alkali reaction again.The principal element that influences the accumulation of TSNA in the tobacco leaf has tobacco type, cultivation technique, the modulation of gathering, storage ageing etc.In various measures, modulation condition is very big to TSNA accumulation influence, so reduce the meaning that tobacco TSNA has particular importance by the change of modulation condition.
Summary of the invention
In order to reduce the generation of tobacco N-unique nitrosamine (TSNA), the invention provides the method for a kind of reduction tobacco N-unique nitrosamine (TSNA).
The technical scheme that the present invention solves its technical problem is: moisture content in leaves content remains under the 40%-50% condition in the modulation room, and the microwave of using the 2450MHz frequency kills microorganism in the leaf to tobacco leaf irradiation about 90 seconds, reduces the formation of tobacco TSNA.
The invention has the beneficial effects as follows, effectively reduce the generation of strong carcinogen tobacco N-unique nitrosamine (TSNA), reduce the harm of tobacco health of smokers.

The specific embodiment
Microwave generator (2) is installed in the metal cabinet among Fig. 1 (1), and placement 300-500mm is thick in the below, and moisture is the tobacco leaf (3) of 40%-50%, and the microwave irradiation that adopts the 2450MHz frequency can kill microorganism in the leaf about 90 seconds, reduced the formation of TSNA.
Adopt wind to send mode to work continuously among Fig. 2, blower fan (4) carries tobacco leaf to pass through from metal cabinet from a side air blast, by microwave irradiation in the process about 90 seconds.
Adopt propulsion mode to work continuously among Fig. 3, propeller (5) carries tobacco leaf to pass through from metal cabinet from a side, from opposite side output, by microwave irradiation in the process about 90 seconds.
Adopt the belt drive mode to work continuously among Fig. 4, drive (7) rotates and drives conveyer belt (6) and carry tobacco leaf to pass through from metal cabinet from a side, from opposite side output, by microwave irradiation in the process about 90 seconds.
Adopt the roll-type kind of drive to work continuously among Fig. 5, transmission is rolled (8) and is carried tobacco leaf to pass through from metal cabinet from a side, from opposite side output, by microwave irradiation in the process about 90 seconds.
Adopt the hanging kind of drive of chain to work continuously among Fig. 6, chain (10) lower draw-bar carries tobacco leaf and carries tobacco leaf to pass through from metal cabinet from a side, from opposite side output, by microwave irradiation in the process about 90 seconds.
Claims (6)
1. method that reduces tobacco N-unique nitrosamine (TSNA), it is characterized in that: moisture content in leaves content also has under the 40%-50% condition in the modulation room, adopts the microwave irradiation tobacco leaf of 2450MHz frequency, kills microorganism in the leaf, reduces the formation of tobacco TSNA.
