Description
Sebastián Piedrahíta-Pérez and co-authors studied how to wash cadmium out of cocoa waste flour in 2024. Cadmium is a toxic metal that cocoa pods can absorb from soil. Pods came from two regions of Colombia, Antioquia and Casanare, and the team mapped where the metal sits in the pod.
Pods from Casanare held nearly twice the cadmium of pods from Antioquia, and about half the metal sat in the pod husk. A scoring matrix picked citric acid as the best wash. At the best settings, the wash removed over 95 percent of the metal. A voltage signal helped judge contact time. The process could add value to cocoa waste at scale.
