Interaction Among Microbiota, Chemical Composition, and Quality Variations in Coffea arabica Across Altitudinal Gradients During Wet Processing

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Fermentation significantly altered the dominant bacterial genera from Sphingomonas and Pleomorphomonas (before fermentation) to Weissella and Lactobacillus (after fermentation), while Cladosporium and Fusarium remained the dominant fungal genera. Notably, non‐volatile compounds in de‐pulping coffee beans and volatile compounds of roasted coffee beans ...
