Example Embodiment

[0032] Example 1

[0033] A roasting method for improving the degradation rate of tobacco leaf protein includes the following steps:

[0034] A. Harvesting: Harvesting fresh tobacco leaves of K326 variety with proper maturity.

[0035] B. Weaving cigarettes: the same rod and the same quality, the same part, and the density is appropriate;

[0036] C. Furnace: Put the tobacco leaves collected in step A into the roasting barn, the same quality as the furnace, and all the packs are full;

[0037] D. Yellowing: including early yellowing, middle yellowing and late yellowing. In the early yellowing period, the temperature of the dry bulb is increased from 27°C to 34°C, and the wet bulb temperature is adjusted from 26°C at a heating rate of 1.5°C / h. To 33℃, stabilize the dry and wet bulb temperature, bake for 16h; then enter the middle of yellowing stage, increase the dry bulb temperature to 38℃ and adjust the wet bulb temperature to 35℃ (the The endopeptidase activity that degrades protein ...

[0048] Example 3

[0049] A roasting method for improving the degradation rate of tobacco leaf protein includes the following steps:

[0050] A. Harvesting: harvesting fresh tobacco leaves of the K326 variety of suitable maturity; the fresh tobacco leaves are the middle leaves of the tobacco plant; the specific performance of the mature tobacco leaves is that the leaf color of the tobacco leaves is light yellow, the main veins are all white and shiny, and the branch veins turn white. The tip and edge of the leaf are rolled down, the leaf surface is wrinkled, there are mature spots, and most of the hairs are off;

[0051] B. Rod weaving and furnace loading: weave the harvested tobacco leaves and put them into the barn for baking; the principle of weaving rods is that the rods are of the same quality, the same position, and the density is appropriate; The principle of loading the furnace is the same quality of the furnace, and the loading is full; the loading density of the said barn ...

Abstract

The invention discloses a curing method for improving the protein degradation rate of tobacco leaves. The curing method comprises the following steps: A. harvesting; B, weaving a rod and charging thatfurnace; C, flue-curing: the flue-cured tobacco leaves are flue-cured after the oven is charged, and the flue-cured tobacco leaves can be obtained through the yellowing period, the color fixing period and the dry rib period. The method of the invention has extremely great significance for ensuring the high-quality raw material supply of the cigarette industry by regulating the curing time, optimizing the curing process, improving the protein degradation rate of the tobacco leaves, regulating the protein content, and improving the quality of the bulk curing tobacco leaves.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco curing, and in particular relates to a curing method for improving the protein degradation rate of tobacco leaves. Background technique [0002] Protein is one of the important components of tobacco and is closely related to the quality of tobacco. The degradation of proteins in plants is generally believed to be firstly acted by endopeptidases, which hydrolyze proteins into polypeptides, and then hydrolyze polypeptides into amino acids by exopeptidases, among which exopeptidases are divided into Aminopeptidase and Carboxypeptidase. During the roasting process, the protein can be degraded, and the amino acids produced can produce aroma substances that are beneficial to the quality of tobacco by reacting with reducing sugars or directly degrading them. If the protein content of the tobacco leaves is high after roasting, the intensity of the smoke will be too high, the aroma and taste w...
