« Soumbala » is traditionally used in Burkina Faso as a food condiment in different communities. This study was conducted to evaluate « soumbala » manufacturing process on its nutritional value in two communities. During this descriptive and analytical study, samples were taken in the « Gouin » and « Moose » communities. The results show that, the humidity rate was higher in « soumbala » and waste in the « Gouin » processus, whereas in the « Moose » one, the highest humidity rate was observed after the cooking step and in peeled boiled seeds. The ash level was higher in raw seeds and after cooking step in the « Gouin » community whereas in the « Moose » community, it was higher in raw seeds and waste. The pH determination showed a progressive increase in pH values during the « soumbala » manufacturing process in the two communities. Mineral elements assays showed a slight variation in grades along the « soumbala » manufacturing process. For biochemical analysis, lipids content increased during the « soumbala » production; protein levels increased a little at the early stages of « soumbala » manufacturing process in both communities and carbohydrates contents were higher in waste in the « Moose » community, whereas in the « Gouin » community, the highest contents were found in the raw seeds. The aflatoxins determination in « soumbala » showed levels below the detection limit of the used method. These results showed that it was imperative that approved standard protocols be adopted to maintain the nutritional quality of « soumbala » wherever it is produced.

The aim of the present study was to assess the microbial quality of five ready-to-eat food such as bread, pasta, rice with sauce, beans and milk sold in five localities of Burkina Faso namely, Ouagadougou, Bobo-Dioulasso, Dakola, Cinkansé and Niangoloko. One hundred and one samples were collected and microbial quality were assessed by evaluating the food hygiene indicators such as total aerobic mesophilic flora, total coliforms, thermotolerant coliforms, yeast and mould. Food safety indicators such as Escherichia coli, Salmonella, coagulase-positive staphylococci, Clostridium perfringens and Bacillus cereus were also tested for contamination. Samples were tested according to ISO guidelines for all parameters. The results showed that 74 (73.27%) of samples were satisfactory while 15 (14.85%) were acceptable and 12 (11.88%) were not satisfactory according to international standards. Among the food safety indicators sought, Escherichia coli was detected in two samples and Bacillus cereus in four samples. Most of the analyzed food exhibited good hygiene behavior within the acceptable limits and the highest of not satisfactory rate was observed in milk powder and rice with sauce. Ouagadougou samples recorded the highest number of not satisfactory samples. Despite the general quality was satisfactory, the presence of specific microorganisms such as coliforms is indicative of the poor hygiene surrounded these foods. It is therefore necessary to train and follow up the vendors in the handling of equipment, hand-washing practices and selling environment hygiene for better improvement of the quality of the street foods.

The aim of the present study was to assess the microbial quality of five different types of food such as bread, pasta, rice with sauce, beans and milk sold in five localities of Burkina Faso. One hundred and one (101) samples were collected and microbial quality were assessed by evaluating the food hygiene indicators such as total aerobic mesophilic flora, total coliforms, thermotolerant coliforms, yeast and mould. Food safety indicators such as Escherichia coli , Salmonella , coagulase-positive staphylococci, Clostridium perfringens and Bacillus cereus were checked too. All samples were analyzed under ISO methods.

La carence en vitamine A constitue un problème de santé publique dans les pays en développement et affecte en particulier les jeunes enfants et les femmes en âge de procréer. Le but de cette étude était d'évaluer l’application de la politique nationale en matière de production et d’importation, des huiles végétales raffinées, d’enrichissement obligatoire en vitamine A au Burkina Faso, à travers la détermination de la teneur en vitamine A et de l'indice de peroxyde des huiles végétales vendues sur le marché. Cette étude transversale a été menée dans cinq villes sélectionnées selon la densité de la population. Cinquante-neuf échantillons d’huile ont été achetés dans ces villes pour évaluer la teneur en vitamine A, l'indice de peroxyde et leur conformité aux normes nationales et internationales. Dans l'ensemble, 76,27% des huiles n'étaient pas suffisamment enrichies en vitamine A. Pour l'indice de peroxyde, 3,39% des huiles n'étaient pas conformes. Globalement, 77,97% des huiles n'étaient pas conformes pour ces deux paramètres. Au regard de ces résultats il est nécessaire d’intensifier la lutte contre la mise à la consommation des huiles non enrichies en vitamine A au Burkina Faso. English title: valuation of the vitamin A content and the peroxide value of vegetable oils commonly sold in markets in Burkina Faso Vitamin A deficiency is a public health problem in developing countries and particularly affects young children and women of childbearing age. The aim of this study was to assess the implementation of the national policy on the production and importation of refined vegetable oils and mandatory vitamin A fortification in Burkina Faso, through the determination of the vitamin A content and peroxide value of vegetable oils sold on the market. A cross-sectional study was conducted in five cities selected according to population density. Fifty-nine oil samples were purchased in these cities to assess vitamin A content, peroxide value and compliance with national and Codex standards. Overall, 76.17% of the oils were not adequately fortified with vitamin A. For the peroxide value, 3.39% of the oils did not comply. Overall, 77.97% of the oils did not comply for these two parameters. In view of these results, it is necessary to intensify the fight against the consumption of oils not enriched in vitamin A in Burkina Faso.
