Embodiment 1

[0030] Test tobacco leaves: the upper tobacco leaves, the 14th to 16th leaves.

[0031] The tobacco leaves roasted according to the process conditions in Table 1 were used as control samples, and the tobacco leaves obtained by roasting according to the process conditions in Table 2 were used as test samples.

[0032] Table 1 Existing process conditions baking parameters

[0033]

[0034] Note: the upper, middle and lower tobacco leaves in the existing curing process all use the process parameters in Table 1.

[0035] Table 2 Upper leaf roasting parameters

[0036]

[0037] The test results of the ammonia release of the control and test samples are shown in Table 3.

[0038] The detection result of ammonia release amount of sample after table 3 baking

[0039] deal with

[0040] It can be seen from Table 3 that the process provided by the present invention has a significant reduction effect on the ammonia release. Compared with the existing baking process, t...

Embodiment 2

[0054] Test tobacco leaves: the middle tobacco leaves, the 9th to 11th leaves.

[0055] The test was carried out according to the method of Example 1. The existing baking process parameters are shown in Table 1, and the setting of the test baking process parameters is shown in Table 7.

[0056] Table 7 Middle leaf roasting parameters

[0057]

[0058]See Table 8 for the detection results of the ammonia release of the control and test samples.

[0059] The detection result of the ammonia release amount of the sample after table 8 roasting

[0060] deal with

[0061] It can be seen from Table 8 that the process provided by the present invention has a significant reduction effect on the ammonia release. Compared with the existing baking process, the ammonia release is reduced from 7.93 μg / g to 6.78 μg / g, a drop of 14.50%.

[0062] The appearance quality of the cured tobacco leaves was evaluated, and the cured whole kang tobacco leaf samples were graded according t...

Embodiment 3

[0075] Test tobacco leaves: the lower tobacco leaves, the 4th to 6th leaves.

[0076] The test was carried out according to the method of Example 1. The existing baking process parameters are shown in Table 1, and the setting of the test baking process parameters is shown in Table 12.

[0077] Table 12 Lower leaf roasting parameters

[0078]

[0079] After the tobacco leaves were cured according to the parameters in Table 12, the ammonia discharge of the test tobacco leaves and the reference tobacco leaves was measured, the grade structure of the tobacco leaves was graded, the sensory quality was evaluated and smoked, and the tobacco leaves were purchased and priced. All indexes of the tobacco leaves were better than those of the comparison tobacco leaves.

Abstract

The invention discloses a modulating process method for reducing a release amount of ammonia in the flue-cured tobacco. By dividing a tobacco flue-curing stage into six continuous stages and setting different wet and dry bulb temperatures, heating rates, relative humidity and baking time for six stages, the release amount of ammonia after tobacco leaves are flue-cured is obviously reduced. Through the adoption of the flue-curing process provided by the invention, not only can the release amount of ammonia in the flue-cured tobacco be reduced obviously, but also the class structure of the tobacco leaves is enabled to be promoted, the proportion of first-class tobacco is increased, smoking quality of the tobacco leaves is promoted, the fragrance quality and the fragrance quantity is improved obviously, irritation and offensive odor are reduced, the price of the baked tobacco leaves is enabled to be risen and the economic value of the tobacco leaves is increased.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf preparation, and relates to a method for curing flue-cured tobacco, in particular to a method for reducing the amount of ammonia in flue-cured tobacco. Background technique [0002] Ammonia is an alkaline gas in the atmosphere, which mainly comes from amino acids, proteins, nitrates, ammonium salts, amides, alkaloids and nitrogen-containing heterocyclic compounds in the process of tobacco leaf preparation and fermentation. Ammonia in mainstream smoke exists in both the gaseous and particulate phases. In cigarettes, an appropriate amount of ammonia is necessary for cigarettes with more carbohydrates and organic acids, but excessive ammonia will produce strong irritation, causing smokers to constrict their throats, feel coughing, and have acrid nose and tongue. Unbearable feeling, long-term inhalation will cause serious harm to the human body. [0003] In order to further promote the implemen...
