Problems solved by technology

[0004] In recent years, the production level of tobacco leaves has been greatly improved, and the intensive curing barns with automatic control are gradually replacing the old ordinary barns. The quality of tobacco leaf curing has been improved, but the setting of the curing conditions is all about the appearance characteristics, aroma and taste, energy saving, efficiency improvement, etc., but no attention has been paid to the release of harmful substances such as benzopyrene, and there are few related patents and literature reports

Embodiment 1

[0028] Test tobacco leaves: upper leaves, 14th to 16th leaves.

[0029] Tobacco leaves roasted in accordance with the process conditions in Table 1 are reference samples, and tobacco leaves roasted in accordance with the process conditions in Table 2 are test samples.

[0030] Table 1 Existing baking process parameter table

[0031]

[0032] Note: The upper, middle and lower tobacco leaves in the existing baking process all use the process parameters in Table 1.

[0033] Table 2 Test baking parameters

[0034]

[0035]

[0036] Table 3 shows the test results of benzopyrene release from control sample tobacco leaves and test sample tobacco leaves.

[0037] Table 3 Test results of benzopyrene release of samples after baking

[0038]

[0039] It can be seen from Table 3 that the process provided by the present invention has a significant reduction effect on the release of benzopyrene. Compared with the existing baking process, the release of benzopyrene is reduced from 11.1ng / g to 8.5ng / g, a...

Embodiment 2

[0053] Test tobacco leaves: upper leaves, 14th to 16th leaves.

[0054] The test was carried out in the manner of Example 1. The existing baking process parameters are shown in Table 1, and the baking process parameters set in this test are shown in Table 7.

[0055] Table 7 Test baking parameters

[0056]

[0057]

[0058] The test results of the benzopyrene release amount of the test samples are shown in Table 8.

[0059] Table 8 Test results of benzopyrene release of samples after baking

[0060]

[0061] It can be seen from Table 8 that the process provided by the present invention has a significant reduction effect on the release of benzopyrene. Compared with the existing baking process, the release of benzopyrene is reduced from 11.1ng / g to 8.6ng / g, a decrease of 22.5. %.

[0062] The appearance quality of the flue-cured tobacco leaves was evaluated, and the samples of the whole kang-cured tobacco were graded according to the national standard 42 of flue-cured tobacco, and the pro...

Embodiment 3

[0075] Test tobacco leaves: middle leaves, 9th to 11th leaves.

[0076] The test was carried out in the manner of Example 1. The existing baking process parameters are shown in Table 1, and the baking process parameters set in this test are shown in Table 12.

[0077] Table 12 Test baking parameters

[0078]

[0079]

[0080] After the tobacco leaves are roasted according to the parameters in Table 12, the benzopyrene release amount of the test tobacco leaves and the comparative tobacco leaves are measured, the grade structure of the tobacco leaves, the sensory quality evaluation and the tobacco leaf purchase pricing are carried out, and the results are the same as those of Example 1 and Example 2. The same, both show that all the indicators of the test tobacco are better than the comparison tobacco.

Abstract

The invention discloses a baking process method for reducing the release amount of benzopyrene in flue-cured tobacco. A tobacco curing process is partitioned into six stages, the dry-bulb temperature is set to gradually raise between 35 DEG C and 68 DEG C, the wet-bulb temperature is 33-42 DEG C, the temperature raising rate is 0.2-0.8 DEG C / h, the relative humidity is 22-87 percent and falls in sequence, the baking time is 13-57 hours, and the first four stages are shorter in baking time while the last two stages are longer in baking time. The six stages are carried out continuously. After baking, the release amount of the benzopyrene in tobacco leaves is lowered by over 20 percent than that of benzopyrene in a blank control, the grade structure of the tobacco leaves is improved, the sensory quality of the tobacco leaves is improved, and the quality and amount of aroma are improved greatly. Moreover, irritation and offensive odor are reduced, the price of the baked tobacco leaves is higher, and the economic value of the tobacco leaves is raised.

Description

Technical field [0001] The invention belongs to the technical field of tobacco leaf preparation, and relates to a flue-cured tobacco baking method, in particular to a modulation process for reducing the release of benzopyrene in the flue-cured tobacco by adjusting the process parameters during the tobacco leaf baking process. Background technique [0002] Benzo[a]pyrene is a typical fused ring aromatic hydrocarbon in flue gas. Polycyclic aromatic hydrocarbons are the products of incomplete combustion of tobacco under high temperature and oxygen-deficient conditions. The organic fragments generated by the pyrolysis of various organics are formed through a complex polymerization process. There are more than one hundred types of fused ring aromatic hydrocarbons in smoke. About 30 carcinogenic fused ring aromatic hydrocarbons have been identified in cigarette smoke. The most typical one is benzo[a]pyrene, which has the highest carcinogenicity. , Followed by fused ring aromatics suc...
