Abstract

The aging is a crucial stage in tobacco processing, which contributes to the reduction of impurities and irritation, and the stabilization of the internal chemical composition of the leaves. However, it usually takes a long time (2-3 years) for the nature aging process of tobacco (20 °C-30 °C, relative humidity of 65-75%), which seriously affects the processing efficiency of tobacco. Microorganisms play an important role in the change of chemical composition and characteristic aromatic substances of tobacco. Acinetobacter, Sphingomonas Aspergillus, Bacilli, and Pseudonocardia is the main microorganism in the aging process of tobacco, which increasing the aromatic substances (such as alcohols, ketones, and esters) by the action of the enzymes and metabolites, and degrade the harmful components (such as alkaloid, nicotine and nitrosamines in tobacco). This review systematically summarizes recent advancements in understanding the primary microbial composition and the changes in chemical composition during tobacco aging. This knowledge is helpful for screening functional strains, and control the process of tobacco aging by the inoculation of these strains.

烤烟老化过程中微生物组成的变化及其对化学成分的影响

陈化是烟草加工的关键阶段，它有助于减少杂质和刺激，并稳定叶片的内部化学成分。但烟叶的自然老化过程（20℃-30℃，相对湿度65-75%）通常需要较长的时间（2-3年），严重影响烟叶的加工效率。微生物在烟草化学成分和特征芳香物质的变化中起着重要作用。不动杆菌、鞘氨单胞菌、曲霉菌、芽孢杆菌和假心菌是烟草老化过程中的主要微生物，它们通过酶和代谢物的作用增加芳香物质（如醇类、酮类、酯类），降解烟草中的有害成分（如生物碱、尼古丁、亚硝胺类）。本文系统地综述了烟草老化过程中主要微生物组成和化学成分变化的最新研究进展。这有助于筛选功能菌株，并通过接种这些菌株来控制烟草的老化过程。
