Tobacco leaf curing process capable of improving curing quality of flue-cured tobacco variety KRK26

Abstract

The invention relates to a tobacco leaf curing process capable of improving the curing quality of a flue-cured tobacco variety KRK26, belonging to the technical field of flue-cured tobacco modulation processes. The curing process comprises the following steps of: regulating the humidity at low temperature to yellow tobacco leaves; stabilizing the temperature and removing moisture for withering; ventilating and dewatering for drying the leaves; and controlling the temperature and the humidity to dry leaf ribs. In the invention, the method of keeping the tobacco leaves at lower temperature to reduce water evaporation in the tobacco leaves and guarantee the water content of the tobacco leaves is adopted to solve the problems of less water and difficult yellowing of the tobacco leaves of the KRK26 variety in the yellowing period; the dry-bulb temperature is between 41 DEG C and 44 DEG C, and the tobacco leaves can be sufficiently dewatered and shrunk to reduce the cell membrane turgor; the tobacco leaf cell membranes cannot be broken between 45 DEG C and 48 DEG C so as to smoothly fix the color; and in the whole process of tobacco leaf curing, the wet bulb temperature is controlled tobe between 34 DEG C and 38 DEG C so as to actively promote the decomposition and the conversion of macromolecular substances and the synthesis of flavoring substances. The invention has the advantages of simple and convenient operation, safety and insurance, can ensure that the tobacco leaves of the variety KRK26 can be smoothly yellowed, timely subjected to color fixing and subjected to rib drying in good time and improves the tobacco leaf curing quality.

Description

Technical field: [0001] The invention relates to a tobacco leaf curing process capable of improving the curing quality of flue-cured tobacco variety KRK26, and belongs to the technical field of flue-cured tobacco modulation technology. Background technique: [0002] KRK26 is a male sterile hybrid bred by Zimbabwe Tobacco Research Institute by crossing MSK326 and RW. No. race), root-knot nematode, bacterial wilt, its yield potential is medium to high, and the quality of tobacco leaves is good. [0003] In 2007, the Yunnan Academy of Tobacco Agricultural Sciences introduced the KRK26 variety. After plot comparison tests and large-scale test demonstrations, the results showed that the tobacco plants grew neatly in the field, the plant type was ideal, the tobacco leaf yield was high, the quality was good, and the quality characteristics Outstanding, resistant to many diseases, deeply loved by the tobacco industry. [0004] KRK26 variety, the appearance color of the tobacco lea...

AI Technical Summary

Problems solved by technology

[0005] In 2009, a trial planting of 30,000 mu was conducted in China's tobacco areas, and the field growth was gratifying and a scene of high yield; however, a major problem occurred during the curing process of tobacco leaves: 30% to 40% of the tobacco leaves of this variety could not be roasted

Furthermore, the Chinese baking process adopts "dry bulb temperature and wet bulb temperature, jumping baking together". , shorten the life activity process of tobacco leaf cells, starch, protein, chlorophyll, and a series of macromolecular substances are not fully decomposed, resulting in insufficient formation of aroma precursor substances and poor roasting quality

[0010] The KRK26 variety tobacco leaf curing process of the present invention, through literature search, does not see the public report identical with the present invention
