AI Technical Summary

Technical Problem

The fermentation process of tobacco leaves is lengthy and uncontrolled, making it difficult to effectively improve the quality of tobacco leaves. Existing microbial enhanced fermentation technologies also face the problem of strain colonization difficulties.

Method used

Tobacco leaf fermentation was carried out using Bacillus pseudomycoides. Biological agents were prepared and mixed with tobacco leaves for fermentation treatment, and culture conditions were optimized to enhance the aroma of tobacco leaves and reduce off-flavors.

Benefits of technology

It significantly enhances the aroma characteristics of tobacco leaves, improves overall quality, shortens fermentation time, reduces the irritation and off-flavors of tobacco leaves, and enhances the sweetness and flavor of tobacco leaves.

Abstract

The application relates to Bacillus pseudomycoides, a biological agent, a tobacco product and a preparation method thereof. The Bacillus pseudomycoides has a preservation number of CGMCC No. 36124. The strain has strong total amylase and beta-amylase activities. By applying the Bacillus pseudomycoides to intensified fermentation of tobacco leaves, the aroma characteristics of the tobacco leaves are enhanced, and the overall quality of the tobacco leaves is improved, thus providing an effective biological technology means for a tobacco fermentation process.
