ABSTRACT: Cottonseed oil is one of the most widely consumed oils in Burkina Faso. Its production evolved from small-scale to industrial production to offer a high-quality refined oil. However, if the refining process is not well controlled, the oil could present a danger to consumers. Therefore, control of the health quality of these oils is necessary. This study was therefore undertaken, and its objective was to evaluate the health quality of cottonseed oils produced in the industrial zones of Ouagadougou and Bobo-Dioulasso, in Burkina Faso. The analyses focused on chemical contaminants and physicochemical quality. The gossypol content was determined by High Performance Liquid Chromatography, and standard methods ISO 3960 and ISO 660 were used to evaluate peroxide value and acid index, respectively. As for chemical contaminants, they were evaluated according to the QuEChERS NF 15662 method for pesticides and by flame atomic absorption for metallic trace elements. The results show an average acid index of 0.23 mg KOH/g, in line with standards, and a peroxide value above the limit in 18.75% of samples, with an average of 7.01 meqO2/Kg. None of the samples contained gossypol, pesticides, lead, or cadmium, thus complying with current health quality standards.
