Abstract

In this study, chemometric method has been used in determining the oil quality. The samples used were olive oil, sunflower oil and butter from two different brands. Two different conditions were applied, either it was fresh or fried. Titratio, a conventional method was used to determine free fatty acids content (FFA), iodine value (IV), and peroxide value (PV). Twelve samples were then used for analysis and their FTIR spectra were measured at 4000-400 cm-1. The computer stimulation was used to process the data based on their pattern recognition which optimized by principal component analysis (PCA) and partial least squares (PLS). PCA model was used to distinguish the properties between fresh and fried oil. The PLS model was used to predict the value for validation test in comparison with conventional results. Results showed the validation value for fresh oil was 0.90. This indicated the chemometric method was in agreement with conventional method.
