Abstract: Fermentation is an important process in determining the quality of cocoa beans. Therefore, studies to determine the rate of fermentation of cocoa beans non-destructively and rapidly are needed. This study aimed to develop a robust model using Vis-NIR and PLS-DA to differentiate cocoa bean samples with different fermentation levels. The PLS-DA calibration and prediction classification model showed reliability (Rel) values above 75% and 73%. Accuracy (Acc) of calibration and prediction were higher than 90% and 87%, respectively. A reliable and robust model has been created, which allows determining the rate of fermentation of cocoa beans non-destructively and rapidly.
