Etude diagnostique des pratiques de friture du thon du mets «Garba» consommé dans la ville d’Abidjan (Côte d’Ivoire)

Abstract

L"objectif de l"étude était d"évaluer l"impact des pratiques de friture du thon du mets «Garba» sur la qualité sanitaire de l"huile de friture. Les pratiques de friture et les taux en composés néoformés ou polaires des huiles ont été déterminés dans les restaurants des communes de Cocody, Yopougon et Abobo à Abidjan. L"étude a revélé que la vente de ce mets est une activité d"hommes (94,9%) n"ayant aucune formation academique (62,8%) pratiquant la friture dans les conditions variées. Trois groupes de vendeurs ont été identifiés selon les pratiques adoptées. Le 1 er groupe est caractérisé par une pratique utilisant des températures inférieures à 160 °C et les huiles contiennent des composés néoformés inférieurs à 25%. Le 2 ème utilise des températures de friture comprises entre 160 °C et 180 °C avec des huiles réutilisées contenant 25 à 75% de composés néoformés. Le 3 ème groupe fait la friture à 180 °C et les huiles réutilisées contiennent 75%. La majorité des huiles analysées contiennent des taux en composés néoformés supérieurs au taux seuil de 25% fixé par le décret français n° 86-857 du 18 juillet 1986. Il ressort de cette étude qu"il y a un risque d"atteinte à la qualité sanitaire de ce mets et par conséquent à la santé des consommateurs.

Validation of an UV-Visible spectrophotometry assay method for the determination of chlorpheniramine maleate tablets without prior extraction

“…Their consequences in terms of public health explain that a number of countries, encouraged by the WHO, have set up national laboratories for quality control of medicines. Unfortunately, due to lack of resources, the latter could not check the quality of all pharmaceutical products circulating in the countries (WHO, 2017;Djibrine et al, 2018;Diabaté et al, 2018;Ihaku et al, 2019). In the treatment of allergy, Chlorpheniramine Maleate, also known as Chlorphenamine Maleate is considered by the World Health Organization (list updated in April 2013) as an essential drug thanks to its effectiveness and lower cost and, is distributed worldwide as a generic compound (Hall and Hall, 2014;Djambeu, 2015).…”

Peroxide Index, Trans Fatty Acids, Acrylamide and Polycyclic Aromatic Hydrocarbons (Pah) Contents in Frying Oils and Fried Tuna Fish Involved in “Garba” Production in Côte d’Ivoire

“…Group 3 is dominated by restorers whose oils contain more than 30% neoformed compounds. Their frying oils are reused until blackening before adding new oil at temperatures from 160˚C to over 180˚C for frying times of 11 to 20 minutes [10].…”

“…Indeed, the use of edible oil at high temperature induces degradation of major components, notably fatty acids which lead to oil oxydation, polymerisation, isomerisation and hydrolyse [9]. Moreover, the overuse of oil leads to the production of a rate of 10% to 40% of frying-induced compounds in fried oil during Garba production marketed in Abidjan [10]. These compounds which appear during heating can be absorbed by the fried products in permanent way.…”

“…This deterioration would come from the initial quality of the oils, most often of an unknown nature, or from different practices such as the application of temperatures from 160˚C to 180˚C, numerous reuses, but also from the frying environment. Indeed, the restaurateurs of this dish adopt the practice of overusing oil with oil additions during frying with traditional open fryers[10]. This common practice in gargotes according to[17], of continuous and repeated use of frying oil is adopted to reduce restaurant owners' expenses.…”

Development and validation of a UV-Visible method for the determination of the active principle Efavirenz in tablets

“…Besides, there is an actual increase in the resistance of usual drugs against infectious diseases. Those combined situations have created a heavy burden on healthcare systems in African countries considering the fact that most of the time there is no quality control performed on the drugs and food entering and or present the market in those countries (Tittikpina, 2013;WHO, 2018;Maïwore et al, 2018;Djibrine et al, 2018;Diabaté et al, 2018;Ishaku et al, 2019). Medicines used against viral infections, caused by HIV-AIDS and hepatitis, are not an exception to this counterfeit.…”
