Application of biotechnology in improving the quality of low-grade tobacco leaves
摘要
The high occupancy rate and low utilization rate of low-grade tobacco leaf resources in China have been recognized as major challenges for the tobacco industry. Excessive content of macromolecular substances in tobacco leaves is one of the key factors leading to inferior quality of tobacco leaves. Using biotechnology to degrade these macromolecular substances, balance chemical components and increase aroma substances is one of the effective ways to improve the quality of low-grade tobacco leaves. In recent years, the application of enzyme technology and microbial technology in improving the quality of tobacco leaves has become a research hotspot in the industry. The influence of macromolecular substances such as starch, protein, pectin and cellulose in tobacco leaves on quality was introduced, and the mechanisms and related research progress of enzymes and microorganisms in tobacco fermentation were sorted out and summarized, aiming to provide reference and inspiration for further promoting the development of this field.
