“…FTIR spectroscopy coupled with chemometrics has been used for authentication of high priced oils including authentication extra virgin olive oil from palm oil (Rohman and Che Man, 2010), authentication virgin coconut oil from palm oil (Rohman and Che Man, 2009), sesame oil from corn oil (Nurrulhidayah et al, 2014), beef fat from dog meat (Rahayu et al, 2018), and authentication of fish patin oil from palm oil (Putri et al, 2019). However, there is a limited study on the application of FTIR spectroscopy in combination with chemometrics for authentication of pumpkin seed oil (PSO).…”

The adulteration practice of high price oils such as pumpkin seed oils (PSO) with lower ones could be motivated by economic gains. The objective of this study was to apply FTIR spectroscopy in combination with chemometrics of multivariate calibrations and discriminant analysis for the authentication of PSO. A total of fifteen oils were scanned using FTIR spectrophotometer at mid-infrared regions (4000-650 cm -1 ) and subjected to principal component analysis (PCA) using absorbance values at whole mid-IR regions to know oil having a close similarity to PSO in terms of FTIR spectra. Two multivariate calibrations namely principle component regression (PCR) and partial least square regression (PLSR) along with FTIR spectra modes (normal, derivative-1, and derivative-2) were optimized to get the best prediction models. In addition, discriminant analysis (DA) was used for classification of PSO and PSO adulterated with oil adulterant. The results showed that among 15 oils, sesame oil (SeO) had the closer score plot in terms of the first principle component and second principle components with that of PSO. Based on the statistical parameters selected (higher R 2 and lowest errors), FTIR spectra in derivative -1 mode at wavenumbers of 1800-663 cm -1 were selected for quantification of PSO in SeO with coefficient of determination (R) values of 0.9998 and 0.9994 in calibration and validation models, respectively. The values of root mean square error of calibration (RMSEC) and root mean square error of prediction obtained were 0.003% and 0.006%, respectively. DA using 10 principle components could clearly discriminate PSO and PSO adulterated with SeO with accuracy levels of 100%. FTIR spectroscopy in combination with chemometrics could be an effective means to detect the adulteration of PSO with SeO.

“…The peak intensity at 3012 cm −1 was proportional to the unsaturation levels in the oils, with a greater intensity at 2922 and 2852 cm −1 , indicative of higher levels of saturation [ 1 ]. Weak features at 1653 cm −1 (C=C stretching), 924 cm −1 (=C-H deformation), and 864 cm −1 (C-C stretching) were visible in the IR spectra of SO, CLO, O3C, and FO [ 38 , 39 ].…”

This study uses Raman and IR spectroscopic methods for the detection of adulterants in marine oils. These techniques are used individually and as low-level fused spectroscopic data sets. We used cod liver oil (CLO) and salmon oil (SO) as the valuable marine oils mixed with common adulterants, such as palm oil (PO), omega-3 concentrates in ethyl ester form (O3C), and generic fish oil (FO). We showed that support vector machines (SVM) can classify the adulterant present in both CLO and SO samples. Furthermore, partial least squares regression (PLSR) may be used to quantify the adulterants present. For example, PO and O3C adulterated samples could be detected with a RMSEP value less than 4%. However, the FO adulterant was more difficult to quantify because of its compositional similarity to CLO and SO. In general, data fusion improved the RMSEP for PO and O3C detection. This shows that Raman and IR spectroscopy can be used in concert to provide a useful analytical test for common adulterants in CLO and SO.

“…Chemometric technique as a good solution for analyzing mixed compounds that have overlapping spectra profiles. The advantages of quantitative chemometric analysis techniques are that mixed compounds can be analyzed without a separation procedure, the technique is very easy to apply, very sensitive, useful, and very cheap compared to other analyzes (Putri et al, 2019;Serva et al, 2021).…”

Melati belanda flowers have two varieties that look different, namely from the shape of the flowers. The first variety has the shape of an elongated flower and the second variety has the shape of a rounded flower. So that, this difference in the shape of the flower will allow generating different activities. The purpose of this study was to identify the distinctive spectra of these two varieties. The method used is a fingerprint analysis of UV-VIS spectroscopy combined with chemometrics for the identification and authentication of varieties of Melati belanda. The results of the analysis of PLSR Combretum indicum Varr. B against Combretum indicum Varr. M on a spectrum of 218.86-252.54 nm, The first derivatization of RMSEC 2.39; R2 0.9975; RMSEP 6.92; R2 0.9939 and RMSEC 5.63; R2 0.9868. Meanwhile, with a wavelength of 253,260 – 299,020, a normal model of RMSEC 2.01 was obtained; R2 0.9983; RMSEP 1.89; R2 0.9985 and RMSEC 1; R2 0.9772. So can be concluded below UV-VIS spectroscopic fingerprint analysis combined with chemometrics is able to identify the authentication of the Combretum Indicum Varr. B against the occurrence of adulteration of flowers Combretum Indicum Varr. M at a wavelength of 253.260 – 299.020 nm of normal models.
