Treatment method for improving tobacco quality

Abstract

The invention discloses a treatment method for improving tobacco quality, and relates to the technical field of tobacco processing. The treatment method for improving tobacco quality comprises the following steps of: performing supercritical CO2 extraction on tobacco, refining an extract and then carrying out molecular distillation to obtain various fractions, performing sensory evaluation, retaining fractions having positive effects on sensory quality, discarding fractions having negative effects on sensory quality of tobacco, also reasonably blending various beneficial fractions according tothe characteristics and design objectives of the tobacco, and then backfilling the extracted tobacco with the blended fractions, thus reaching the purpose of tobacco upgrading. According to the treatment method for improving tobacco quality, the sensory quality of tobacco can be obviously improved, offensive odor of the tobacco is remarkably reduced, stimulation is reduced, the aroma quality andaroma volume are remarkably improved, the strength is moderate, and the aftertaste is more comfortable.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a treatment method for improving the quality of tobacco leaves. Background technique [0002] The quality of tobacco leaves is the most important factor affecting the quality of cigarette products. It can be said that good cigarette products cannot be separated from good tobacco leaves. my country is the world's largest producer of tobacco leaves, but the output of high-quality tobacco leaves is limited and cannot meet the needs of cigarette production. It relies heavily on imported high-quality tobacco leaves, which has resulted in a shortage of high-quality tobacco leaves and a backlog of low-quality tobacco leaves , a contradiction that cannot be effectively utilized. With the rapid consumption upgrade of the cigarette product market in recent years, this contradiction has become increasingly prominent and has become the biggest bottleneck restricting the developmen...

Problems solved by technology

The process of this method is relatively simple, and the treated tobacco leaves can be used directly. However, during the dry cleaning process, although some substances that have a negative effect on the quality of the tobacco leaves are eluted, some substances that contribute to the aroma quality in the tobacco leaves are also greatly lost. Tobacco leaves with insufficient aroma will cause flat aroma after washing and cannot achieve real quality improvement

In addition, the subcritical fluid used in this method is one or more mixtures of propane, butane, tetrafluoroethane, and dimethyl ether. These substances are flammable, explosive, and extremely volatile, which poses a production safety hazard.
