- UNESP researchers evaluated nine cocoa clones under fermented and pre‑dried postharvest systems at the Frederico Afonso Experimental Station in Rondônia.
- Fermentation cut bean sugars by over 95% and tannins by nearly 50%, while boosting amino acids, antioxidant enzymes, potassium and magnesium.
- Unfermented beans retained higher phosphorus and calcium, minerals linked to bone and cardiovascular health.
- Glycine betaine and proline were detected in cocoa beans for the first time, providing powerful antioxidant activity.
- Clone CCN 51 displayed a balanced profile across fermentation, while Clone EEOP 63 was the most productive and Clone EEOP 96 retained high phenolics when unfermented.
- Blend strategy of combining a fermented base with a proportion of unfermented beans is proposed to deliver both traditional chocolate flavor and enhanced health benefits.
Why it matters: Cocoa growers and chocolate makers stand to gain higher prices as the blended beans command premium flavor and health benefits, while consumers receive a more nutrient‑rich product; the study’s findings could shift market demand toward Amazonian cocoa over lower‑quality beans.
