[0005] The invention patent published by the Chinese Patent Application No. 201210472117.0 mentions that n-butyraldehyde is used as a false template, α-methacrylic acid is used as a functional monomer, methanol is used as a porogenic solvent, and ethylene glycol dimethacrylic acid is used as a Ester is used as a cross-linking agent, and the adsorbent is synthesized by bulk polymerization method, and added to the composite filter rod, which can significantly reduce the release of crotonaldehyde in cigarette smoke; the invention patent with application number 201310062529. 3. According to the specific ratio of alcohol as the raw material, the filter stick intercepting agent is prepared. Through the effective addition of the intercepting agent when the filter stick is formed, the release of crotonaldehyde in cigarette smoke can be effectively reduced; the application number published by the Chinese patent is 201210039344.4 The invention patent provides a method of irradiating tobacco leaves or finished cigarettes by electron beam / X-ray irradiation generated by an electron accelerator, so as to reduce the release of crotonaldehyde in cigarette smoke; Good results have been achieved in terms of release amount, but no attention has been paid to reducing the release amount of crotonaldehyde in cigarette smoke by threshing, redrying and aging of tobacco leaves, and there are no related patents and literature reports

Embodiment 1

[0020] The 2011 C3L tobacco leaf sample from a certain place in the central part produced according to the existing threshing and re-baking process parameters was used as a blank sample; according to three groups of different process parameters and optimized processing parameters, the leaves were threshed and re-roasted, and the other process parameters were unchanged. The obtained tobacco leaf samples 1-3 and optimized samples; the tobacco leaf samples of each group were loosened and rehydrated under the same conditions, cut into shreds, and dried naturally, and then rolled into cigarette samples. The detection of crotonaldehyde release in smoke of the samples is shown in Table 1.

[0024] It can be seen from Table 1 that the amount of crotonaldehyde released in the flue gas of the tobacco samples produced under the opt...

Embodiment 2

[0026] Tobacco leaves produced according to the existing threshing and re-baking process parameters in the middle of a place in 2011 were used as blank samples; the other process parameters were unchanged, and the samples of biological reagents were added as optimized samples. bacillus and circulant bacillus, according to the mass percentage ratio of 1:1:2, water is used as solvent to prepare a 1.2‰ biological preparation aqueous solution, and the bacterial content of Bacillus megaterium in the biological preparation is 1×10 12 CFU / g, Bacillus amyloliquefaciens bacteria content 1×10 10 CFU / g, Bacillus circulans content 1×10 10 CFU / g; the samples were alcoholized under the same conditions, loosened and regained moisture under the same conditions, cut into shreds, and dried naturally, and rolled into cigarette samples. The detection of crotonaldehyde release in the smoke of the samples is shown in Table 2, and 1% in the table means that the added amount of the biological agent ...

Embodiment 3

[0032] Tobacco leaves produced according to the existing threshing and re-baking process parameters in the middle of a place in 2011 were used as blank samples; the other process parameters were unchanged, and the samples of biological reagents were added as optimized samples. Bacillus, Bacillus circulans, and Bacillus subtilis, according to the mass percentage of 1:1:1:2, with water as solvent, prepared into 0.6‰ biological preparation aqueous solution, the bacteria content of Bacillus megaterium in the biological preparation is 1× 10 12 CFU / g, Bacillus amyloliquefaciens bacteria content 1×10 10 CFU / g, Bacillus circulans content 1×10 10 CFU / g, Bacillus subtilis content 1×10 15 CFU / g; the samples were alcoholized under the same conditions, loosened and regained moisture under the same conditions, cut into shreds, and dried naturally, and rolled into cigarette samples. The detection of crotonaldehyde release in the smoke of the samples is shown in Table 3. In the table, 2% m...

Abstract

The invention discloses a redrying and mellowing method for reducing the crotonaldehyde release amount. The method includes a tobacco flake redrying process and a mellowing process. The mellowing process includes the step of adding mellowing agents in redried tobacco flakes, wherein the mellowing agents are biological agent aqueous solutions, and biological agents are one type or multiple types of bacillus subtilis, bacillus megatherium, bacillus circulans, bacillus amyloliquefaciens bacillus freeze-dried powder. According to the method, the biological agents are added as the mellowing agents, degradation and conversion of crotonaldehyde in tobacco raw materials can be effectively promoted in the tobacco mellowing process, the process of reducing the crotonaldehyde release amount in cigarette smoke is carried out before the tobacco threshing, redrying and mellowing stages, and the method has important theoretical significance and practical application value by combining the tobacco threshing and redrying process and the mellowing process.

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 the amount of crotonaldehyde released. Background technique [0002] Crotonaldehyde is known to be a volatile carbonyl compound with a relatively high content in smoke. It is irritating to the conjunctiva, nose and upper respiratory tract mucous membranes and skin. Long-term exposure can cause chronic rhinitis, dermatitis, respiratory diseases and nervous system diseases. System dysfunction. In 2009, the Zhengzhou Tobacco Research Institute led a study on the cigarette smoke hazard index of Chinese-style cigarettes. Among the 29 harmful components in mainstream cigarette smoke, 7 representative components were selected as cigarette hazard evaluation indicators. Croton Aldehydes are one of them. Therefore, research on reducing the release of crotonaldehyde in cigarette smoke is of great significance for improving the quality...
