Detailed description of the invention
Below by embodiment, technical scheme is described in further detail.
Embodiment 1
The tobacco sample weighing 0.8g loads quartz glass tube, is separately added into 30mg 2,6-di-t-butyl-4-methyl simultaneously
Phenol (is called for short BHT), is placed in quick tubular type heating furnace, with N2Or air as reaction atmosphere, gas flow control is
2.1L/min, after ventilation 3min, is warming up to 800 DEG C with the heating rate of 20 DEG C/s, and at 800 DEG C, insulation stops 10min, uses sword
Bridge filter disc trapping granule phase substance.After being incubated, open after heating furnace continues ventilation cooling 5min and take off cambridge filter.Before and after trapping
The mass change of cambridge filter is i.e. pyrolyzed the tar content of generation.
After being pyrolyzed, cambridge filter is turned up and is placed in bottom boiling flask, launch, be subsequently added 0.01mol/L acetic acid
Ammonium salt solution (containing the internal standard) 50mL, stoppers bottleneck with rubber stopper, with the speed oscillation 30min of 180r/min, stands 5min；Through micropore
Filter membrane filter pressing, to chromatogram bottle, carries out LC-MS/MS analysis.Inner mark method ration is used to measure the concentration of NNK in extracting solution.Concrete number
According to see table 1.
As can be known from Table 1,2,6-di-tert-butyl-4-methy phenols have and preferably reduce the Main Tobacco Planting in cigarette smoke
The effect of the peculiar N-nitrosamine NNK of grass, compared with comparison Medicated cigarette, the reduction amplitude to NNK is 54.19%.
Table 1
| NNK(ng/g) | Total reduction rate | |
| Blank tobacco shred | 581.25 | -- |
| Tobacco shred containing BHT | 266.25 | 54.19% |
Embodiment 2
(1) by 2,6-di-tert-butyl-4-methy phenol is dissolved in ethanol, ultrasonic 30min, it is thus achieved that concentration is the 2,6-of 2mg/mL
Di-tert-butyl-4-methy phenol ethanol solution.This solution is applied on tobacco shred, then dries tobacco shred, it is thus achieved that containing 2,6-bis-
The tobacco shred of tert-butyl-4-methyl-Phenol, in tobacco shred 2, the content of 6-di-tert-butyl-4-methy phenol is 20mg/g.
(2) by above-mentioned containing having 2, the tobacco shred of 6-di-tert-butyl-4-methy phenol is fabricated to Medicated cigarette, numbering A1, every volume
Cigarette A1 about 18mg Han 2,6 di tert butyl 4 methyl phenol.
Embodiment 3
(1) preparing a cavity filter stick, the middle part of this cavity filter stick has cavity, by powder 2,6-di-t-butyl-4-
Methylphenol is directly added in the cavity of this cavity filter stick, then wraps up filter stick by forming paper, it is thus achieved that containing 2, and 6-di-t-butyl-
The cigarette filter rod of 4-methylphenol, in this filter stick 2, the content of 6-di-tert-butyl-4-methy phenol is that 18mg/ props up；
(2) by above-mentioned containing 2, the cigarette filter rod of 6-di-tert-butyl-4-methy phenol is connected with cigarette makes Medicated cigarette, numbering
A2。
Comparative example
Without 2, the blank Medicated cigarette of 6-di-tert-butyl-4-methy phenol, numbering A0.
In addition to above-mentioned restriction, embodiment 2,3 and comparative example use essentially identical tobacco raw material and technique to prepare Medicated cigarette.
Analyze detection 1
According to the mensuration gas phase color of Nicotiana tabacum L. peculiar N-nitrosamine in GB/T 23228-2008 cigarette mainstream smoke total particulate matter
Spectrum-heat energy analysis combination method, analyzes Medicated cigarette A0～A2.
| NNK (ng/ props up) | Reduction rate | |
| A0 | 4.52 | |
| A1 | 3.11 | 31.2% |
| A2 | 3.37 | 25.4% |
In Medicated cigarette A1 and A2 main flume, the content of NNK is greatly reduced, this explanation 2, and 6-di-tert-butyl-4-methy phenol is used
In Medicated cigarette, such as, it is added on tobacco shred or in cigarette filter rod, it is possible to effectively reduce tobacco-specific nitrosamine in cigarette mainstream flue gas
Content, especially reduces the content of NNK.
Analyze detection 2-Sensory Quality of Cigarette to evaluate
According to the Sensory Quality of Cigarette evaluation criterion in GB GB 5606.4-2005, Medicated cigarette A0～A2 is smoked panel test, knot
Fruit is as shown in table 1.
Table 2
After specialty Medicated cigarette sensory evaluating smoking personnel smoke panel test, it is believed that Medicated cigarette A1～A2 and Medicated cigarette A0 is in overall mouthfeel and suction
Taste aspect is basically identical.This explanation 2,6-di-tert-butyl-4-methy phenol adds in Medicated cigarette, has substantially no effect on the sense organ of Medicated cigarette
Quality.
Finally should be noted that: above example is only in order to illustrate that technical scheme is not intended to limit；To the greatest extent
The present invention has been described in detail by pipe with reference to preferred embodiment, and those of ordinary skill in the field are it is understood that still
The detailed description of the invention of the present invention can be modified or portion of techniques feature is carried out equivalent；Without deviating from this
The spirit of bright technical scheme, it all should be contained in the middle of the technical scheme scope that the present invention is claimed.
