HYDROCARBONS

Coconut (Cocos nucifera) is a widely consumed tropical fruit highly valued for its nutritional and therapeutic qualities, with its oil as a major component used in food, cosmetics, and traditional medicine. Recently, polycyclic aromatic hydrocarbon (PAH) contamination of edible oils has led to concerns regarding the safety of coconut oil, especially its processing and storage practices. The aim of this study was to identify the concentrations of PAHs in some coconut oil products available in Edo State, Nigeria, to assess potential contamination and associated health risks. Coconut oil samples were collected from major markets in Edo State and analyzed using gas chromatography-mass spectrometry (GC-MS) following solvent extraction, sample cleanup using silica gel, and rotary evaporation concentration. The analysis showed that PAH levels in all tested coconut oil samples were below the detection limit (<0.05 mg/kg), indicating no significant contamination. This suggests that the processing methods and storage conditions of the sampled oils were sufficient to prevent PAH formation. The findings emphasize the importance of continued monitoring and adherence to best practices in oil extraction, storage, and distribution to maintain product safety and protect consumers who may not have sufficient knowledge.
