Problems solved by technology

[0003] At present, the methods and means for reducing the amount of protein released in tobacco mainly use the addition of protease and other biological enzyme preparations in tobacco to promote the degradation of protein. These methods have a more significant effect on reducing protein in tobacco and are also widely used, but This method also has some shortcomings, such as the coordination of biological enzyme preparation and cigarette aroma, the increase of cigarette cost, etc.

Embodiment 3

[0098] In this example, Yunyan 87 is used as the material, and the tobacco leaf samples come from concentrated and contiguous tobacco fields with an area of ​​about 200 mu and a relatively flat terrain. The tobacco leaf transplanting period, fertilization and management measures are basically the same. The growth, development and maturity of the tobacco leaves are normal, and the size, position, nutritional level and maturity of the tobacco leaves are basically the same, and the leaves are in the 9th to 11th positions in the middle. Tobacco leaves with consistent maturity were harvested, and the test tobacco leaves were listed according to the leaf position requirements before harvesting. Based on the classification of fresh tobacco leaves, the same stalk is of the same quality. When loading cigarettes, the pole distance between the upper and lower layers is balanced and consistent to ensure that the fresh weight of a single pole is basically the same.

[0099] Tobacco leaves...

Abstract

The invention discloses a flue-curing process method capable of reducing protein content in the flue-cured tobacco. The process method disclosed by the invention is implemented according to the following steps of: A, preparing the flue-cured tobacco and placing the flue-cured tobacco into flue-curing equipment; B, sequentially carrying out six continuous flue-curing stages comprising four short-time flue-curing stages and two long-time flue-curing stages in the flue-curing process of the flue-cured tobacco; C, after flue-curing, obtaining the flue-cured tobacco with low protein content. According to the invention, on the premise of ensuring quality of the flue-cured tobacco, the step of controlling the content of a protein which is an important nitrogen-containing compound is migrated to the tobacco leave modulating stage, so that the flue-curing process method is helpful for improving chemical quality of tobacco leaves, and thus, damage of smoking to health of human bodies is further reduced. By the process conditions of the flue-curing process method, compared with a flue-cured sample in a conventional method, the flue-cured tobacco leaves has the advantages that the appearance quality, the proportion of medium-class and first-class tobacco and the smoking quality are all improved and the release amount of the protein is reduced by 15 percent to 25 percent.

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 protein content in flue-cured tobacco. Specifically, it is a six-stage curing process of "four short and two long" (that is, four short-time curing stages and two long-term curing stages), which can reduce the risk of contamination of flue-cured tobacco by adjusting the process parameters during the tobacco leaf curing process. Baking process method for protein content. Background technique [0002] In the production of tobacco leaves, under the given tobacco types, varieties, and cultivation conditions, the modulation and processing process is closely related to the changes in the chemical components of tobacco leaves. Protein is the basic component of the protoplasm of all plant cells, and most of the nitrogen contained in biological tissues exists in protein. The protein in tobacco leaves hardly contribute...
