This study evaluated the effects of fermentation and drying durations on the physical and chemical quality of cacao beans produced in Brgy. Sto. Niño, Koronadal City, South Cotabato. A 3 x 3 factorial experiment arranged in a Completely Randomized Design with three replications was used. The treatments consisted of three fermentation durations (6, 7, and 8 days) and three drying durations (5, 6, and 7 days). The quality parameters assessed were moisture content, pH, bean weight, bean count, defect percentage (moldy, slaty, and purple beans), bean purity, and bean grade. Data were analyzed using two-way Analysis of Variance and Least Significant Difference tests at the 5% level of significance. Results showed that fermentation and drying durations significantly influenced moisture content, with 7 days of fermentation combined with 6 to 7 days of drying producing moisture levels nearest the safe range for storage. Fermentation significantly affected pH, with 7 days producing a balanced acidity level, while drying significantly affected bean weight and bean count. Defect parameters and bean purity were not significantly affected, and all treatment combinations met Grade 1 standards with more than 90% purity. The study concludes that coordinated fermentation and drying management is essential in stabilizing moisture, improving acidity, and maintaining commercial bean quality. The recommended protocol is 7 days of fermentation followed by 6 to 7 days of drying for consistent Grade 1 cacao beans.
