Abstract

Keting fish (Mystus gulio) is a local fish from Indonesia. The quality of keting fish oil needs to be maintained to avoid counterfeiting. The use of Fourier transform infrared (FTIR) spectroscopy can be developed for quantitative analysis of keting fish oil (KFO) in binary mixtures with palm oil (PO) and patin fish oil (PFO). In this present research, PLS and PCR models were used to construct a multivariate calibration for the KFO content in the binary mixtures analyzed at fingerprint region frequencies of 1500-1000 cm-1. The results showed that PLS with second derivative FTIR spectra was well suited for quantitative analysis of KFO-PFO with a value of the coefficient of determination (R2) = 0.997 and the error expressed as root mean square error of calibration (RMSEC) = 0.0204. Meanwhile, R2 0.999 and RMSEC values obtained for KFO in a mixture with PO were and 0.0133. In general, FTIR spectroscopy serves as a suitable technique for the determination of KFO in mixtures with other oils.

Abstract

This research aims to see the quality of red fruit oil (RFO) before and after being treated with activated carbon and bentonite. The quality of red fruit oil can be seen from the analysis of physicochemical characterization determination, which includes the determination of acid value (AV), peroxide value (PV), saponification value (SV), iodine value (IV), and p-anisidine value (PAV). In this study, AV RFO ranged from 9,22-10,23 mg KOH/g, PV RFO ranged from 5,57-7,56 meq/kg, SV RFO ranged from 96,57-110,24 mgKOH/g, IV RFO ranged from 70,00-70,83 gI2/100g, and PAV RFO ranged from 5,97-7,00 meq/kg. The purification of RFO using activated carbon and bentonite significantly (p<0,05) affected the physicochemical characteristics of the oil, where the process succeeded in improving the quality of RFO by reducing acid value, peroxide value, saponification value, and p-anisidine value and increasing iodine value.
