Abstract

The detection and quantification of hogwash oil in soybean oils by means of absorption spectroscopy is presented. Three types of soybean oils were adulterated with different concentrations of hogwash oil. The spectra were measured in the visible band using a white LED and a low-cost spectrometer. Then, the visible spectra were sliced into two bands for modeling a simple setup made of two LEDs only, and the best LED couple was experimented. The successful results indicate potentials for implementing a smartphone-compatible device for a quick assessment of soybean oil quality.
