Embodiment 1

[0051] The verification test was carried out in Anlong, Qianxinan, Guizhou Province in 2017. The variety of flue-cured tobacco tested was Yunyan 87. The tested tobacco leaves were cultivated and managed according to the standardized production of local high-quality tobacco leaves, and harvested according to the maturity standard. The test barn is a standard dense barn.

[0052] 1.1 Experimental design

[0053] Taking the main local baking process as the control, and taking the "Ten Key Stable Temperature Points of Qingtianxiang 442" as the treatment, a comparative experiment was carried out to precisely control the baking process.

Abstract

The invention discloses a baking process of ten key stable temperature points of sweet and fragrant tobacco leaves. Wet key points, full yellowing key points, soft and wilting key points, semi-dry key points of tobacco leaves, key points of main vein turning white, key points of aroma formation, key points of balanced color and key points of tobacco leaves drying Toasting, through this process, the macromolecular substances of the tobacco leaves can be fully degraded, a large number of small molecular substances (aroma precursor substances) are formed, and the tobacco leaves are fully softened and withered. In order to improve the softness of the tobacco leaves, increase the aroma and oil content of the tobacco leaves, and enhance the color of the tobacco leaves , providing a favorable safeguard against stiffness.

Description

technical field [0001] The invention relates to a baking process of "442" ten key point tobacco leaves, belonging to the field of flue-cured tobacco baking. Background technique [0002] Guizhou mountainous sweet-flavored tobacco leaf production areas are distributed in the southwest of Guizhou and the western mountainous area of ​​Wumeng Mountain in the northwest of Guizhou, including: Qianxinan Prefecture, Liupanshui City, Weining County, Hezhang County, and Nayong County of Bijie City, which belong to low latitude, medium and high altitude The hilly and mountainous ecological region is affected by both the Indian Ocean monsoon climate and the Pacific monsoon climate. The rainfall in winter and spring is small, and the rainfall in summer and autumn is heavy. The climate is cool and sunny, and the temperature difference between day and night is relatively large. The field production of Qingtian flavor is vigorous, fully developed, dry matter accumulated fully, and the chara...
