Preliminary flue-curing method for Honghua Dajinyuan tobacco leaves, obtained tobacco leaves and application thereof

Abstract

The invention belongs to the field of tobacco curing, and particularly relates to a preliminary flue-curing method for Honghua Dajinyuan tobacco leaves. The method comprises the steps that fresh Honghua Dajinyuan tobacco leaves are subjected to six-stage flue-curing, and the six-stage flue-curing includes a yellowing earlier stage, a yellowing intermediate stage, a yellowing later stage, a fixation earlier stage, a fixation later stage and a stem drying stage, wherein the flue-curing temperature of the yellowing earlier stage is 32-33.5 DEG C, and the difference between the flue-curing temperature and the wet bulb temperature is 0.5-1 DEG C. The invention further relates to the tobacco leaves obtained through the method and application thereof in tobacco products. The preliminary flue-curing method can improve the Honghua Dajinyuan grade quality, the auxiliary set tobacco proportion is decreased, the average price of Honghua Dajinyuan flue-cured tobacco is increased, and the appearancequality, the chemical composition and sensory quality of the flue-cured tobacco are improved.

Description

technical field [0001] The invention belongs to the field of tobacco preparation, and in particular relates to a method for primary curing of Honghua Dajinyuan tobacco leaves, and also relates to the tobacco leaves prepared by the method and the application of the prepared tobacco leaves in tobacco products. Background technique [0002] At present, the traditional three-stage curing process is still widely used for curing tobacco leaves, and the general operation steps are as follows: [0003] 1) Yellowing stage: After ignition, the baking temperature rises to 34°C-36°C at a rate of 1°C / hour, and the wet bulb temperature is kept at 1°C-1.5°C lower than the dry bulb temperature (baking temperature) until 85°C More than 80% of the tobacco leaves in the bottom shed turn yellow; raise the curing temperature to 40°C-42°C, and keep the wet bulb temperature at 36°C-37°C, so that the tobacco leaves turn yellow and soften; [0004] 2) Color-fixing stage: the baking temperature rise...

AI Technical Summary

Problems solved by technology

The inventors of the present invention have found that: if the traditional three-stage curing process is used to initially roast the safflower big gold yuan tobacco leaves, many secondary smokes such as blue and black smoke, variegated smoke, and blue and yellow smoke are often roasted, which seriously affects the quality of the tobacco leaves.
