Coffee cultivated in Latin America, southern Asia, and tropical Africa, undergoes a complex process to reach its final form. The fruit, consisting of multiple layers, includes the mucilage, an inedible outer layer with a bitter taste, and the bean, the edible part known as coffee parchment. Farmers employ various post-harvest methods, such as wet, dry, or semi-dry processing, to separate the bean from the fruit.
Among these, the wet method, utilizing fermentation, is the most prevalent, facilitated by enzymes, acids, and alcohols produced by microorganisms. Fermentation, a metabolic process utilizing sugar and producing diverse metabolites, significantly influences the chemical composition of coffee beans and, consequently, their cupping quality. Roasting also holds a pivotal role, affecting taste and aroma by altering volatile compounds present in green coffee. Additionally, roasting induces caramelization, enhancing flavor, while managing fat oxidation is crucial to maintain coffee quality.
This study aims to investigating the impacts of fermentation and roasting on key chemical compounds in coffee, aiming to discern their influence on overall coffee quality
