Problems solved by technology

The above patents use biological compound enzymes to treat tobacco stems, which effectively improves the smoking quality of tobacco stems, but the activity of the compound enzymes is limited to a certain extent. The treatment method is a combination of multiple enzymes. It is easy to be degraded by protease, resulting in loss of activity. It takes several hours to process too long, which cannot meet the needs of continuous production

Abstract

The invention discloses a method by combining biological enzyme and microwave expansion technologies to improve quality of tobacco stems. The method comprises the following steps of preparing a biological enzyme treatment liquid by composite enzyme and natural extracts, soaking the tobacco stems by the biological enzyme treatment liquid, partially degrading lignin, cellulose, pectin and the like, hydrolyzing large-molecule matters, and promoting the synthesizing, conversion and accumulation of small-molecule compound; utilizing the microwave expansion to improve the fragrance components of the tobacco stems, so as to realize the loose physical structure of the tobacco stems and effectively improve the filling value. The method has the advantages that a novel concept is provided for the comprehensive treatment of the tobacco stems, the process is simple, and the operation is easy; the offensive odor of the treated tobacco stems is obviously reduced, the fragrance is obviously improved, the comfortability is improved, and the significant meanings on the improvement of smoking quality of the tobacco stems, effective utilization of tobacco resources, reduction of injury and decrease of tar are realized.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing and relates to quality improvement of tobacco stems, in particular to a method for improving the quality of tobacco stems by combining biological enzyme treatment and microwave expansion technology. Background technique [0002] The tobacco stem is the component part of the tobacco leaf, which accounts for about 25% of the tobacco leaf. However, the content of cellulose in tobacco stems is high, the components such as sugar and alkali are relatively low, and the macromolecular substances such as starch and protein contained in tobacco stems make the tobacco stems have many miscellaneous gases and heavy odors, and the aroma and taste are not enough. And due to the lack of proper preparation methods, a large amount of tobacco stems are discarded every year, which not only causes environmental pollution, but also wastes resources. Therefore, the full utilization of tobacco stems has becom...
