Good public health depends in part on a healthy diet. In Senegal, where oil is the main dish, the quality of the oil remains a key issue. The objective of this study was to assess the biochemical quality of selected edible oils marketed in Senegal by determining the various chemical indices. Samples of four oil varieties (Jadida, Jador, Bon Appétit, and Chef Aïda) were collected from Dakar markets. The results showed that, with the exception of Chef Aïda oil, the oils studied met Codex Alimentarius standards for saponification, iodine, acid, ester, and peroxide values. Chef Aïda oil had an acid index of 5.61 mg KOH/g, exceeding the Codex limit of 4.0, while other oils remained within safe thresholds, indicating a possible deterioration in the quality of this oil. An acid index above the Codex limit suggests hydrolysis of triglycerides, potentially producing free fatty acids associated with rancid flavor and reduced shelf-life. The findings reflect data from specific batches and may not represent brand-wide quality.
