A high level of polyunsaturated fatty acid (PUFA) in bandeng oil nanoemulsion (BON) makes it risky to be adulterated using low-quality oils such as palm oil (PO). Authentication of BON is essential to guarantee product quality and safety. Adulterated nanoemulsion is particularly challenging to identify because the surfactant matrix and aqueous phase mask the characteristic odor, color, and specific chemical markers detectable in bulk oils. This research aims to perform the authentication of BON using FTIR spectroscopy combined with chemometrics. Adulteration models were built using palm oil as an adulterant, bandeng oil as a pure component, and nanoemulsion matrix. All samples were analyzed using ATR-FTIR spectroscopy at 4000 – 650 cm-1 wavenumbers. Chemometrics technique, such as principal component analysis (PCA), partial least squares regression (PLSR), and principal component regression (PCR), was performed to separate and quantify BON from adulterant. PCA successfully separated BON from palm oil (PO) as an adulterant. Therefore, PLSR using normal spectra at wavenumbers 1500 - 650 cm-1 had the best value based on highest R2cal value 0.9503; R2pred value 0.8761; lowest RMSEC 0.145; RMSEP 0.245. It can be concluded that FTIR spectroscopy combined with chemometrics was claimed as rapid, accurate, and suitable for authenticating BON from PO as an adulterant in nanoemulsion form.
