A processing method for preparing shredded stems with low crotonaldehyde release

Abstract

The invention belongs to the technical field of tobacco processing, and in particular relates to a processing method for preparing cut stems with small crotonaldehyde release amount. According to the method, tobacco stems are adopted as the raw material, and the method comprises the steps of water-washing pre-treatment, spraying of yeast aqueous solution to the tobacco stems, fermentation treatment, tobacco stem pressing and shredding treatment. According to the processing method, through the matched use of the fermentation procedure and the amino acid adding procedure, on one hand, the content of crotonaldehyde precursor is reduced, on the other hand, the release of crotonaldehyde is inhibited, and thus the technical purpose of reducing the release amount of crotonaldehyde is well realized. Further, due to the adoption of biological enzyme and the adding of the amino acid component, the foreign flavor of cut stems is effectively removed, meanwhile, the maillard reaction product in the smoke is increased, and the sensory quality of cigarettes is improved and stabilized. The processing method has the advantages that the processing method is simple, the operation is convenient and rapid, the cost is low, the safety is high, the large-scale and industrialized application is facilitated, and the method has the significant application value for improving the quality of cigarettes and expanding the application range of cut stems.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a processing method for preparing shredded stems with low crotonaldehyde emission. 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 blended...

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
