New research into Amazonian cocoa reveals that its value may extend beyond flavor alone.Chocolate from the Amazon is already known worldwide for its distinctive taste, but new research suggests it may offer even greater value. Scientists at São Paulo State University in Brazil found that post-harvest methods, especially fermentation, along with careful selection of cocoa varieties, can enhance both flavor and nutritional content. These improvements could help expand the product’s appeal in global markets.
“Unlike soybeans, corn, and wheat, which are priced by volume, cocoa is one of the few agricultural products where quality is much more significant in determining price. In this study, we saw that Amazonian cocoa has the potential to excel in both areas. That’s why we selected the best cultivar and post-harvest practices to achieve nutritional and flavor quality,” said Renato de Mello Prado, a professor at the Faculty of Agricultural and Veterinary Sciences (FCAV) at UNESP’s Jaboticabal campus who led the study.
Funded by FAPESP, the research took place at the Frederico Afonso Experimental Station, part of the Executive Committee of the Cocoa Farming Plan in Rondônia, Brazil. The team examined nine cocoa clones using two processing approaches: traditional fermentation and pre-drying without fermentation.
The project brought together researchers from several institutions, including the Brazilian Agricultural Research Corporation in Porto Velho, the Federal University of Rondônia , and the Federal University of Amazonas.
Fermentation and Nutritional Trade-Offs
“Fermentation is an important process in chocolate production. Without it, the cocoa bean doesn’t develop the color and aroma we know, but there’s a significant nutritional cost to this process,” says Edilaine Istéfani Franklin Traspadini, a FAPESP postdoctoral fellow.
“For that reason, we suggest creating blends that combine fermented and unfermented beans as a strategy to balance flavor and nutritional value. This strategy could increase the value of Amazonian cocoa in the chocolate market, following a very similar approach to that of the coffee sector,” she says.
