Objectives: Dacryodes edulis is tropical multi-purpose tree, which produces fruits for human consumption. Unfortunately, this fruit grown in Côte d'Ivoire is still unknown to the public and is the subject of very few studies. The present study aims to characterize D. edulis fruits starting from their morphological to chemical properties. Methodology and Results: Ripe fruits were collected from 3 sites (CNRA-Azaguié, Azaguié-Blida and GrandMorié). The morphological characteristics measured (weight, length, diameter and pulp thickness) and identified 2 Ivorian safou varieties: D. edulis var. edulis and D. edulis var. parvicarpa. The proximate composition was as follow: moisture (43.02-46.80%), protein (18.66-20.20%), lipid (48.39-52.66%), ash (0.83-1.40%), crude fibre (2.70-3.13%), carbohydrate (14.66-17.82%) and vitamin C (3.06-3.36%). Based on the mineral analysis, the results showed that the most abundant mineral was calcium (531.31-1337.02 mg/kg), followed by potassium (552.39-646.05 mg/kg), zinc (130.48-136.18 mg/kg), sodium (51.54-108.01 mg/kg), magnesium (23.13-73.18 mg/kg), manganese (25.96-26.86 mg/kg) and iron (4.91-8.67 mg/kg). Most of high levels of nutrient content were observed in D. edulis var. edulis. Conclusions and application of findings: Dacryodes edulis fruits are potential source of essential nutrient for Ivorian people and its oil could be used to develop cosmetic products.

La qualité des farines infantiles utilisées pendant la période de sevrage du nourrisson est d'une grande importance. Le but de cette étude était de mettre au point une formulation d'une farine infantile fabriquée à partir de maïs enrichie au safou. Pour ce faire, différentes compositions de farines de maïs et de safou ont été préparées : les farines composées FC 1 (maïs 90% + safou 10%), FC 2 (maïs 80% + safou 20%), FC 3 (maïs 70% + safou 30%) et FC 4 (maïs 60% + safou 40%). Les caractéristiques physico-chimiques, microbiologiques et organoleptiques de ces farines ont été déterminées selon les méthodes standards. Les résultats ont révélé que l'incorporation de la poudre de safou à la farine de maïs a amélioré significativement les paramètres biochimiques notamment la teneur en protéines et la valeur énergétique des différentes farines composées. Les charges microbiologiques détectées dans ces farines ont été inférieures aux critères microbiologiques applicables aux farines infantiles. Toutes les bouillies préparées à partir des farines composées ont été appréciées. Toutefois, la farine FC 3 a regroupé tous les critères d'une bonne farine infantile. Cette formulation pourrait alors être recommandée pour les nourrissons, contribuant ainsi à lutter contre la malnutrition infantile.

Trema guineensis is a woody plant distributed in tropical forest of which leaf and bark extracts are traditionally used for the treatment of various diseases including fever, bronchitis, and gastrointestinal disorders. Previous studies have highlighted their antibacterial activity. So, present work was designed to examine the phytochemical and antifungal properties of aqueous crude extract of T. guineensis leaves. The bioactive components extracted from leaves were tested against pathogenic fungi using the agar tube dilution method. Antifungal activity of aqueous leaves extracts was carried out against selected pathogenic fungal strains as Aspergillus fumigatus, Cryptococcus neoformans and Candida albicans. The phytochemical analysis of the aqueous crude extract revealed the presence of secondary metabolites widely reported as antifungal such as flavonoids, saponins, quinones, alkaloids, polyphenols. The results showed that the aqueous crude leaves extract of T. guineensis was effective in inhibiting the fungal growth and were active against A. fumigatus, C. neoformans and C. albicans with MIC and MFC ranged from 20 to 200 mg/mL and 100 to 400 mg/mL, respectively. The efficient antifungal activity of T. guineensis from the present investigation revealed that aqueous leaf crude extract of the selected plant had a moderate potential to inhibit the growth of pathogenic fungal strains. This finding showed that the aqueous extract of T. guineensis exerted an antifungal effect on C. albicans, A. fumigatus and C. neoformans and supports its traditional use in herbal medicine.

Extra-intestinal pathogenic E. coli (ExPEC) strains are usually able to cause infections in anatomical sites outside of the intestinal tract and are associated with urinary tract infections, neonatal meningitis and septicemia. ExPEC, like commensal E. coli, can colonize

“Soumbara” is a fermented product sold in the markets of several West African countries. In the markets, it is sold in several formats (granulated, powder, and paste). The objective of this study was to evaluate the microbiological and physicochemical characteristics of these three types of “Soumbara” sold in the Korhogo markets. For this purpose, a preliminary survey followed by a sampling of 54 samples of “Soumbara” was carried out. The microorganism load count was carried out according to microbiological standards. The pH, titratable acidity, and moisture content were measured, respectively, with a pH meter, by dosing with sodium hydroxide solution and by differential weighing after passing the sample through the oven. The pH of the different samples is around 6. The moisture content is higher in “Soumbara” paste (20-24.7%) than in powdered (7.3-9.3%) and granulated (8.6-10.7%) “Soumbara.” The acidity rates are between 0.07 and 0.13%, 0.2 and 0.3%, and 0.08 and 0.1%, respectively, for the granulated, powder, and paste types. Mesophilic aerobic germ loads (6.17-8.38 log10 cfu/g) for all three types of “Soumbara” are above the standard. Total coliform (1.13-2.96 log10 cfu/g), mould (0.86-2.52 log10 cfu/g), and yeast (0.33-1.53 log10 cfu/g) loads are below standard. The microbiological quality of the three types of “Soumbara” is unsatisfactory. Overall, “Soumbara” powder is the most contaminated, followed by granulated and paste “Soumbara.” “Soumbara” must be added during culinary preparations in order to avoid possible public health problems.
