“…There are several methods to test the quality of cooking oil, such as dielectric sensor [1,2], NMR spectroscopy [3], VIS-NIRS [4], Differential Scanning Calorimetric (DSC) [5], FTIR-ATR [6], Gas Chromatography -Flame Ionization [7] and others. Each of these methods has its test parameters to determine the feasibility of a cooking oil product.…”

The interaction between triglyceride molecules in cooking oil can be described by Van der Waals interaction which the potential energy between molecules is fulfilled by the potential energy of Lenard-Jones. This study aims to obtain relative dissociation energy in palm oil and animal oil using electro-optics polarization. In the experiment, we measured the change of light polarization as the sample was induced by potential difference or so-called electro-optics. The relative potential of Lenard-Jones as a function of the relative molecular distance was assumed proportional to the average change of electro-optics polarization as a function of potential difference. The results show that in this experimental condition, palm oil has relative dissociation energy greater by a factor of 100 than animal oils, and it decreases after the sample is heated. The observation of Van der Waals interaction through the electrooptic polarization is a new perception and it relatively can be achieved by using a simpler polarization experiment.

“…Oil quality testing using only one parameter in the form of polar components can be done by methods such as chromatography, dielectric sensors, NMR, and NIR [2]. Whereas Sangdehi [3] and Yavari et al [4] examined the formation of polar molecules, the emergence of free fatty acids during use, and changes in viscosity after consumable oils, using VIS-NIRS spectroscopy. Gerde et al [5] have also investigated oil degradation based on the formation of polar components, free fatty acids, and dienoic acid using NIR Spectroscopy, as the fastest device.…”

An integrated polarizer was designed as an alternative test tool to evaluate quality of cooking oils. Integrated Polarizer was composed of light source with wavelength of 532 ± 10 nm, polarizer, analyser, cuvette, electrodes, and high voltage source. In this research, the tool works based on the fluorescence polarization method. Measurements were made by observing the fluorescence polarization angle changes that occur and by applying an external electric field at the samples using high voltage of 0-9 kV in the parallel plate. The results show that the expired cooking oil has a greater polarization angle than the edible cooking oil. The results also show that the change in the polarization angle will increase in proportion to the increase of the heating time. The condition of saturated fatty acids in each sample has an effect on the change of polarization angle.

The purpose of this research is to extract spectral reflectance characteristics of concretes through basic experiment on concrete specimens and site experiment on actual concrete structures using a field portable spectrometer and a VNIR hyperspectral sensor. A spectrometer (GER-3700) and a VNIR hyperspectral camera (AisaEagle VNIR Hyperspectral Camera) were utilized for extracting spectral characteristics of concrete specimens. Concretes normally show similar patterns that have correlation above 80%, while the highstrengthened concretes display very different results from the normal-strength concretes. We also made a certain conclusion in the laboratory experiment on concrete specimens that both the spectrometer and the VNIR camera vary in spectral reflectance depending on concrete strengths.
