Abstract

The invention discloses a curing process suitable for flue-cured tobacco variety NC-YATAS6 tobacco leaves. The curing process harvests mature fresh tobacco leaves of the NC-YATAS6 variety for baking, and the curing includes the yellowing period, withering period, and color fixing The early stage, the late stage of color fixation and the dry gluten stage. The fresh tobacco leaves of the NC-YATAS6 variety are roasted by the process of the present invention. Compared with the conventional roasting process, the chroma is fuller, and the average price of the tobacco leaves is much higher than that of the conventional process technology. At the same time, the tobacco leaves obtained by adopting the curing process of the present invention not only have excellent curing quality and better smoking quality, but also improve the industrial usability of the cured tobacco leaves, significantly increase the economic benefits, and are easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco, and in particular relates to a curing process suitable for NC-YATAS6 variety tobacco leaves. Background technique [0002] Tobacco is an annual or limited perennial herb belonging to the genus Nicotiana in the family Solanaceae, native to South America and cultivated all over the world. Flue-cured tobacco is the tobacco type with the largest cultivation area in my country and the world, and is the main raw material for the cigarette industry. The NC-YATAS6 variety tobacco leaves are the male sterile first-generation hybrid of flue-cured tobacco. [0003] NC-YATAS6 variety tobacco, the plant type is tower type, the leaf shape is oblong, the leaf color is green, the stem and leaf angle is medium, and the main vein is medium in thickness. Its main agronomic and botanical characters, the overall appearance quality and overall sensory quality of the cured tobacco leaves are comparable to t...
