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, saving energy, improving efficiency, etc., but the release of harmful substances such as phenol is not paid attention to, and there are no related patents and literature reports. On the premise of ensuring the quality of tobacco leaves, reducing the release of phenol is of great value for improving the safety of cigarette smoking and the quality of cigarettes

Embodiment 1

[0051] The flue-cured tobacco in this embodiment selects the middle leaves (9-11 leaves) of the cultivar Yunyan 85 in Fengdu County, Chongqing as the test object, and the fresh tobacco leaf samples come from the same tobacco field and the same farmer, so the transplanting period, harvesting and field management The measures are the same, the soil water and fertilizer are uniform, and the growth of tobacco leaves is normal and consistent. The roasting is carried out in the local intensive barn. When weaving the poles to load the tobacco, it is ensured that the fresh weight of each pole is basically the same, and the distance between the upper, lower, left and right poles in the kang is balanced and consistent. Tobacco leaves cured under the existing process conditions were used as control samples, and the test samples of the present invention were cured according to the parameter conditions provided in Table 1 below. After the curing, the phenol release amount of the sample tob...

Embodiment 2

[0065] The upper leaves (13-15 leaf positions) of the cultivar Yunyan 85 in Fengdu County, Chongqing were selected as the test object, and the selection of fresh tobacco leaf samples and the preparation of the baking test were the same as in Example 1. The test samples of the present invention were baked according to the parameter conditions provided in Table 5 below. After the curing, the phenol release amount, appearance quality and internal quality of the sample tobacco leaves were analyzed and tested.

[0067]

[0068] See Table 6 for the detection results of the phenol release amount of the samples. It can be seen that the process provided by the invention has an obvious effect on reducing the release of phenol, and compared with the existing baking process, the release of phenol can be reduced by 45.70%.

Embodiment 3

[0078] The upper leaves (13-15 leaf positions) of the cultivar Yunyan 85 in Fengdu County, Chongqing were selected as the test object, and the selection of fresh tobacco leaf samples and the preparation of the baking test were the same as in Example 1. The test samples of the present invention were baked according to the parameter conditions provided in Table 9 below. After the curing, the phenol release amount, appearance quality and internal quality of the sample tobacco leaves were analyzed and tested.

[0081] See Table 10 for the detection results of the phenol release amount of the samples. It can be seen that the process provided by the invention has an obvious effect on reducing the release of phenol, and compared with the existing baking process, the release of phenol can be reduced by 31.57%.

Abstract

The invention discloses a baking technology method capable of reducing the phenol release amount in flue-cured tobaccos. The technology method includes the following steps that A, the flue-cured tobaccos are prepared; B, six continuous braking stages are needed for baking the flue-cured tobaccos and include four short-period baking stages and two long-period baking stages, and the requirements are that the dry-bulb temperature of baking is 28 DEG C -70 DEG C, wet bulb temperature of braking is 20 DEG C-50 DEG C, relative humidity is 20-95%, and baking time is 4 h -72 h; C, in the six baking stages, dry bulb technology temperature and wet bulb technology temperature are continuously increased, the temperature rate is 0.1 DEG C-5 DEG C / h, and baking time is 4 h-72 h; D, the flue-cured tobaccos low in phenol content are obtained after baking. Through the technology conditions, the phenol release amount can be reduced by 20-50%, and appearance quality and interior quality are better than those of flue-cured tobaccos baked through an existing technology. The baking technology method has the advantages of being significant in effect and very high in operability, and chemical agents and cost addition are not needed.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf preparation, and in particular relates to a curing process capable of reducing the release of phenol in flue-cured tobacco. Background technique [0002] The content of phenolic substances in flue-cured tobacco is significantly higher than that of air-dried tobacco leaves prepared under the same conditions. Phenolic substances such as phenol are harmful to human health. Studies have shown that phenol has a strong stimulating effect on the skin and respiratory mucosa. One of the important factors of tobacco safety, so reducing the release of phenol in tobacco leaves is an important topic to reduce the harm of tobacco. [0003] Tobacco phenol is mainly produced by pyrolysis of lignin and cellulose in tobacco leaves. At present, the means and methods to reduce phenol in tobacco mainly include filter stick adsorption technology, auxiliary material and formula design, and adjustment of silk making...
