Cadmium mitigation in cocoa

The main agricultural, biotechnological, and post-harvest strategies for reducing cadmium (Cd) concentrations in the cultivation and processing of cocoa (Theobroma cacao L.), one of Latin America's most representative products, are reviewed. The study, focusing on Ecuador and other countries that produce fine aroma cocoa, evaluates techniques such as microbial bioremediation, phytoremediation with hyperaccumulator plants, the use of organic amendments and biochar, as well as post-harvest practices such as mucilage drainage and prolonged fermentation. The results highlight the effectiveness of combining biological and technological solutions to reduce cadmium bioavailability, improve bean quality, and comply with international food safety standards, contributing to more sustainable and competitive cocoa production.
