The physicochemical properties of adulterated, unadulterated, crude and bleached palm oil samples were determined so as to access the impact
of additives and bleaching on the oil samples. The adulteration was done by introducing Sudan dyes (azo dyes) in the sample. Physical properties
of the samples, such as Free Fatty Acid (FFA), moisture content, peroxide value, Specific Gravity (S.G) and colour were measured using standard
methods. Fourier Transform Infra-Red (FTIR) Spectroscopy was also carried out on the oil samples to determine the effects of the dye and
bleaching on the chemical composition of the samples. From the results obtained, the values of the physical properties measured were higher in
the adulterated samples than in the unadulterated samples. The value of the Free Fatty Acid (FFA) for Crude Unadulterated Palm Oil (CUPO) was
10.67% and that of th.. Read More»
