Embodiment 1

[0024] The tobacco leaf sample produced according to the existing threshing and redrying process parameters is used as a blank sample; in the tobacco sheet redrying process, the lower tobacco leaves are X3F in a certain place in 2011, the middle tobacco leaves are C3L in a certain place in 2011, and the upper tobacco leaves are B3F in a certain place in 2011. The process parameters were adjusted according to the combination of optimized processing process parameters, and the process parameters of other processes were kept unchanged, and the tobacco leaf samples produced were optimized samples; the tobacco leaf samples of each group were loosely rehydrated, shredded, and naturally air-cured under the same conditions, and the cigarette samples were rolled. The detection of NNK content in flue gas of the samples is shown in Table 1.

Embodiment 2

[0029] The tobacco leaf sample produced according to the existing threshing and redrying process parameters was used as a blank sample; Add the same proportion of biological agent aqueous solution, the biological agent is composed of Bacillus pumilus, Bacillus amyloliquefaciens, and Bacillus licheniformis, after the ratio of 2:1:2 by mass percentage, use water as the solvent to prepare a 1.0‰ biological agent aqueous solution , the content of Bacillus pumilus in biological preparations is 1×10 14 CFU / g, Bacillus amyloliquefaciens bacteria content 1×10 11 CFU / g, Bacillus licheniformis content 1×10 12 CFU / g, the technological parameters of the other processes remain unchanged, and the tobacco leaf samples obtained from production are optimized samples; the cigarette samples are rolled after aging under the same conditions, loosening and rehydration under the same conditions, shredding, and natural drying. The detection of NNK content in the flue gas of the samples is shown in ...

Embodiment 3

[0034] The tobacco leaf sample produced according to the existing threshing and redrying process parameters was used as a blank sample; Add the same proportion of biological agent aqueous solution, the biological agent is composed of Bacillus megaterium and Bacillus licheniformis, after the ratio of 2:1 by mass percentage, use water as solvent, and prepare a 0.8‰ biological agent aqueous solution, the biological agent Bacillus megaterium Bacteria content 1×10 15 CFU / g, Bacillus licheniformis content 1×10 12 CFU / g, the technological parameters of the other processes remain unchanged, and the tobacco leaf samples obtained from production are optimized samples; the cigarette samples are rolled after aging under the same conditions, loosening and rehydration under the same conditions, shredding, and natural drying. The detection of NNK content in the flue gas of the samples is shown in Table 3.

Abstract

The invention discloses a redrying and alcoholizing method for reducing the release amount of NNK. The method comprises the tobacco flake redrying procedure and the tobacco flake alcoholizing procedure. The alcoholizing procedure comprises the step that an alcoholizing agent is added into redried tobacco leaves, wherein the alcoholizing agent is a water solution of a biological agent and the biological agent is one or more of bacillus pumilus, bacillus megaterium, bacillus licheniformis and freeze-dried bacillus amyloliquefaciens powder. In the method, the biological agent is added to serve as the alcoholizing agent, degradation and conversion of the NNK in tobacco leaf raw materials can be effectively improved in the tobacco leaf alcoholizing process, the process of reducing the release amount of the NNK in cigarette smoke is realized in the threshing redrying and alcoholizing stage in advance, the threshing redrying process and the alcoholizing process are organically combined, and the redrying and alcoholizing method for reducing the release amount of the NNK has important theoretical significance and practical application value.

Description

technical field [0001] The invention belongs to the field of tobacco processing, and in particular relates to a method for redrying and aging to reduce NNK release. Background technique [0002] The full name of NNK is 4-(methylnitrosamine)-1-(3-pyridyl)-1-butanone, which is a kind of tobacco-specific nitrosamine (TSNA), and its possible formation mechanism is: nicotine in Nitrosation is formed during tobacco modulation, processing, cigarette smoking, or at the moment of smoke inhalation. NNK is a strong animal carcinogen, which can induce lung cancer in mice, rats and Syrian golden voles. [0003] On June 16, 2006, the State Tobacco Monopoly Administration issued the "Notice of the State Tobacco Monopoly Administration on Further Promoting the Work of Harm Reduction and Coke Reduction" (Guoyanke [2006] No. 412), which proposed new measures for the work of harm reduction and coke reduction. Require. The notice regards seven harmful components in cigarette smoke including ...
