Literature review of cocoa drying technologies and their role in increasing added value

Cocoa is a major Indonesian export commodity, yet predominantly exported as raw beans, limiting value addition. This review examines cocoa drying technologies and their translation into economic value. Proper drying reduces moisture to safe levels, prevents fungal contamination and aflatoxin, and preserves quality attributes such as flavor and polyphenols. Temperature control (optimum 50–55°C) is critical to avoid defects like case-hardening. Traditional sun drying is cost-effective and develops desirable flavor but suffers from inconsistency and contamination risk. Mechanical methods offer speed and control but can reduce quality if mismanaged. Hybrid solar and greenhouse dryers achieve higher efficiency, faster drying, and more consistent quality, leading to higher-grade beans. Drying directly impacts economic value through bean grade, market price, and premium market suitability, especially when integrated with fermentation and storage. However, adoption of advanced dryers is hampered by high costs, limited technical knowledge, and structural constraints. Emerging innovations such as energy-efficient systems, circular use of by-products, and digital agriculture offer sustainable opportunities. Optimizing drying technology is therefore essential for enhancing cocoa quality, value addition, and Indonesia’s global competitiveness.
