Embodiment 2

[0022] The tobacco leaf sample produced according to the existing threshing and re-baking process parameters was used as a blank sample in 2011 X3F tobacco leaves from a certain place; Composed of Bacillus, Bacillus amyloliquefaciens and Bacillus circulans, according to the mass percentage ratio of 2:1:1, water is used as solvent to prepare 1.0‰ biological preparation aqueous solution, and the bacterial content of Bacillus subtilis in the biological preparation is 1× 10 14 CFU / g, Bacillus amyloliquefaciens bacteria content 1×10 9 CFU / g, Bacillus circulans content 1×10 10 CFU / g, the sample was aged under the same conditions, loosened and regained moisture under the same conditions, cut into shreds, and dried naturally, and then the cigarette samples were rolled. The detection of benzo[a]pyrene content in the smoke of the samples is shown in Table 2. In the table, 2% is the addition amount of the biological agent aqueous solution, which is the mass percentage of the cigarette ...

Embodiment 3

[0028] The tobacco leaf sample produced according to the existing threshing and redrying process parameters was used as a blank sample in X3F X3F in 2011; Composed of Bacillus subtilis and Bacillus circulus, after mass percentage ratio of 1:2, water is used as solvent to prepare a 1.5‰ biological preparation aqueous solution, and the bacterial content of Bacillus subtilis in the biological preparation is 1×10 13 CFU / g, Bacillus circulans content 1×10 12 CFU / g, the sample was aged under the same conditions, loosened and regained moisture under the same conditions, cut into shreds, and dried naturally, and then the cigarette samples were rolled. The detection of the benzo[a]pyrene content in the smoke of the samples is shown in Table 3. In the table, 2% is the addition amount of the biological agent aqueous solution, which is the mass percentage of the cigarette sheet.

Embodiment 4

[0033] The tobacco leaf sample produced according to the existing threshing and redrying process parameters was used as a blank sample in X3F X3F in 2011; Composed of Bacillus subtilis, Bacillus megaterium, Bacillus circulans, and Bacillus amyloliquefaciens, after proportioning according to the mass percentage of 1:1:1:3, use water as a solvent to prepare a 0.5‰ aqueous solution of biological preparations. Subtilis subtilis in biological preparations Bacillus bacteria content 1×10 10 CFU / g, Bacillus megaterium bacteria content 1×10 10 CFU / g, Bacillus circulans content 1×10 14 CFU / g, Bacillus amyloliquefaciens bacteria content 1×1014 CFU / g, the sample was aged under the same conditions, loosened and regained moisture under the same conditions, cut into shreds, and dried naturally, and then the cigarette samples were rolled. The detection of the benzo[a]pyrene content in the smoke of the samples is shown in Table 4. In the table, 2% is the addition amount of the biological age...

Abstract

The invention discloses a redrying and mellowing method reducing benzo [a] pyrene release amount in cigarette smoke. The method comprises the steps of a tobacco flake redrying procedure and a mellowing procedure, wherein the mellowing procedure comprises the steps of adding a mellowing agent into redried tobaccos; the mellowing agent is a biological agent aqueous solution; the biological agent is one or more of bacillus subtilis, bacillus megatherium, bacillus circulans and bacillus amyloliquefaciens freeze-dried powder. According to the method, the biological agent is added as the mellowing agent, and can effectively promote degradation and conversion of benzo [a] pyrene in a tobacco raw material during tobacco mellowing, the reduction of the benzo [a] pyrene release amount in the cigarette smoke is preposed in threshing redrying and mellowing stages, and the method organically combines the threshing redrying and mellowing processes, and has important theoretical significance and a 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 the amount of benzo[a]pyrene released in cigarette smoke. Background technique [0002] Benzo[a]pyrene is a typical polycyclic aromatic hydrocarbon (referred to as PAH) in smoke. Polycyclic aromatic hydrocarbons are the products of incomplete combustion of tobacco under high temperature and anoxic conditions. The organic fragments generated by the pyrolysis of various organic substances are formed through a complex polymerization process. There are more than 100 kinds of fused-ring aromatic hydrocarbons in smoke, and about 30 carcinogenic fused-ring aromatic hydrocarbons have been identified in cigarette smoke, the most typical of which is benzo[a]pyrene, which is the most carcinogenic , followed by condensed aromatic hydrocarbons such as dibenzo[a,h]anthracene and benzo[b]fluoranthene. In 2009, the Zhengzhou Tobacco Resea...
