Coffee is a critical agricultural commodity and is used to produce premium beverages enjoyed by people worldwide. The microbiome of coffee beans has proven to be an essential tool that improves the flavor profile of coffee by creating aromatic flavor compounds through natural fermentation. This study investigated the natural microbial consortium during the wet process fermentation of coffee onsite in Thailand in order to identify the correlation between microbial diversity and biochemical characteristics including flavor, aroma, and metabolic attributes. Our study found 64 genera of bacteria and 59 genera of yeast/fungi present during the fermentation process. Group of microbes, mainly yeast and lactic acid bacteria, that predominated in the process were significantly correlated with preferable flavor and aroma compounds, including linalyl formate, linalool, cis-isoeugenol, trans-geraniol, and (-)-isopulegol. Some of the detected metabolites were found to be active compounds which could play a role in health.
咖啡是一种关键的农产品,用于生产全球人们喜爱的优质饮品。咖啡豆的微生物群已被证明是一种重要工具,它通过自然发酵产生芳香风味化合物来改善咖啡的风味特征。本研究调查了泰国当地咖啡湿法加工发酵过程中的天然微生物群落,以确定微生物多样性与包括风味、香气和代谢特性在内的生化特征之间的相关性。我们的研究发现,在发酵过程中存在64属细菌和59属酵母/真菌。在这个过程中占主导地位的微生物群,主要是酵母和乳酸菌,与较好的风味和香气化合物显著相关,包括甲酸芳樟酯、芳樟醇、顺式异丁香酚、反式香叶醇和(-)-异胡薄荷醇。一些检测到的代谢物被发现是可能对健康有作用的活性化合物。
