Issue Ensuring the Safety and Quality of Copra
Diliman Quezon City Page 3 of 13 Among the principal sources of major exposure of humans to PAHs is through consumption of edible oils. This is because edible oils require the drying of vegetable seeds before oil extraction, the resulting combustion fumes may be high in PAHs, which would eventually reach the commercial oil [21, 22].

NMR Determination of Free Fatty Acids in Vegetable Oils - MDPI
In edible oils, FFA are undesirable, as high FFA content results in increased losses during refining, poor flavour quality and stability of the finished edible oil and rancidity of the oil [10,11,12]. At an industrial level, FFA are usually removed from crude oil through a refining procedure, but the process is not 100% efficient.
