Phenotypic, physicochemical, sensory, and functional attributes of cocoa (Theobroma cacao L.) from Brazilian Amazonian floodplain and upland ecosystems

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Cocoa (Theobroma cacao L.) from the Brazilian Amazon plays an important role in national production. While most cocoa is cultivated in upland systems, floodplain ecosystems represent a traditional and distinct production environment that may influence bean composition and quality.
