A treatment method for reducing the release of crotonaldehyde from shredded stems

Abstract

The invention belongs to the technical field of tobacco processing, and particularly relates to a treatment method for lowering the cut stem crotonaldehyde release amount. The method comprises the steps of uniformly spraying a yeast aqueous solution into cut stems for fermentation treatment, drying the cut stems and the like for taking the cut stems as application objects. According to the method, by means of co-use of the fermentation process, the amino acid adding process and the like, on one hand, the crotonaldehyde precursor content is lowered, and on the other hand, release of crotonaldehyde is inhibited, so that the technical objective of lowering the crotonaldehyde release amount is achieved. Furthermore, by adopting a biological enzyme and adding the amino acid component, foreign flavor of the cut stems is effectively removed, Maillard reaction products in smoke are increased, and the cigarette sensory quality is improved and stabilized. In a word, the treatment method has the advantages of being simple, easy to implement, low in cost, high in safety and the like, large-scale and industrial application is promoted, and important application value is achieved for improving the cigarette quality and expanding the cut stem application range.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a treatment method for reducing the release amount of crotonaldehyde in shredded stems. Background technique [0002] Shredded stems are thin filaments of a certain width made from tobacco stems through a series of processes such as shredding and expansion. They have the characteristics of low tar release, good filling performance, and low cost. They are a commonly used raw material for tobacco production. However, due to the large difference between the chemical composition of the cut stems and the shredded leaves, these differences lead to the shortcomings of the cut stems on the one hand, such as large sensory irritation and obvious miscellaneous gas, and on the other hand, the volatile carbonyls such as crotonaldehyde in the cut stems The release amount is higher than that of shredded leaves, so that the release amount of crotonaldehyde in cigarettes bl...

AI Technical Summary

Problems solved by technology

However, it should be noted that most of these methods are developed and designed for reconstituted tobacco leaves or crotonaldehyde in tobacco leaves, and are not suitable for application in the tobacco stem treatment process. In addition, these treatment processes are relatively cumbersome, so it is difficult to be popularized and applied in the tobacco stem treatment process. , it is still necessary to develop a targeted treatment method for reducing the release of crotonaldehyde for cut stems
