Method for treating tobacco stems through biological enzyme, prepared cut stems and prepared cigarettes

Abstract

The invention provides a method for treating tobacco stems through biological enzyme, prepared cut stems and prepared cigarettes. The method comprises the steps that (1), the tobacco stems are pretreated, pressed and cut to obtain the cut stems; (2), compound enzyme liquid is sprayed to the cut stems; (3), the cut stems are spread in a fermentation device and then fermented, multiple layers of material supporting plates are distributed in the fermentation device, and the spreading thickness of the cut stems on each layer of material supporting plate is controlled to be 30-600mm; and (4), the cut stems are expanded and dried to obtain the finished cut stems. By regulating the spreading thickness of the cut stems, the spreading thickness is increased so that the cut stems per unit weight canbe in a low-oxygen environment, enzyme related to the internal toughness of the cut stems is passivated, and the breakage rate of the cut stems is obviously decreased on the basis that the sensory quality of the cut stems is kept stable; the breakage rate of the prepared cut stems is low, the wood gas, irritation and burning sensation of the cut stems are significantly reduced, and aroma components are significantly increased; and the cut stems are applied to the cigarettes, and the processing quality and sensory quality of the cigarettes are improved.

Description

technical field [0001] The invention relates to a method for treating tobacco stems with biological enzymes, and the prepared shredded stems and cigarettes, belonging to the technical field of tobacco processing. Background technique [0002] Shredded stems are shredded tobacco products prepared from tobacco stem raw materials through a series of processes. Shredded stems have the characteristics of low tar and nicotine content and good filling performance. They are one of the main fillers in cigarette formulations and play an important role in cigarette formulations. [0003] From the perspective of biomass, any biochemical process and metabolism cannot do without the participation of enzymes. In recent years, in the process of tobacco processing, adding enzyme preparations can shorten the aging time of tobacco and change the internal chemical composition of tobacco. [0004] Generally, the cut stem preparation process includes: tobacco stem rehydration (stem washing), st...

AI Technical Summary

Problems solved by technology

However, the shredded stems prepared by the existing technology and equipment have high crushing rate, poor uniformity, unstable quality, relatively rough quality, and the sensory quality of shredded stems is not good.
