Abstract:
The frog represents an important food resource for the people of the city of Man (Cote d'Ivoire). For conservation purposes, frogs often go through a smoking-drying stage before being put on the market. The microbiological tests allowed the detection of the presence of Total Aerobic Mesophilic flora, staphylococci, total coliforms, Escherichia coli as well as Salmonella sp. at respective averages of 4.8.106 CFU/g, 5.105 CFU/g, 1.23.106 1.79.104 CFU/g, 4.97.104 CFU/g. The values obtained are not satisfactory, they exceed the required standards, and this is due to the poor storage conditions, and the lack of hygiene of the traders. The water content was determined by the method of A.O.A.C (2008), the content of total carbohydrates and lipids were determined respectively by the method of Munsen and Walker [1], and by the method of Folch, Lees and Stanley (1957). The average water content of the analyzed samples is 5.5%, the lipid content is 6.66 g/100 g and the carbohydrates are in trace amounts. Minerals were determined by x-ray fluorescence spectrometer. The results reveal the presence of Iron, Manganese, Potassium, Zinc, Calcium, and Phosphorus.
