In the context of the valorization and the development of local products in Côte d’Ivoire, this study is based on juices samples prepared from the pulp of wild fruits of Baobab (Adansonia digitata), Tomi (Tamarindus indica) and Néré (Parkia biglobosa). The physiochemical characteristics such as dry matter (desiccation, 105°C), mineral (spectrophotometer), ash, fat, fiber and protein (AOAC), Energy (coefficients), vitamins A & C (HPLC), organic acids & total polyphenols (HPLC), carbohydrate (by difference), pH and titratable acidity (titrimetry, NaOH) of pasteurized juices (75°C, 5 min) were investigated. Data showed that the juices have been characterized by low protein (0.21-0.28 %), fat (0.26-0.65 %) and ash (0.20-0.47 %) content and high level of total carbohydrates (21-30 %) and energy (85.83-124.43 Kcal/100mL). Baobab and Tomi juices were distinguished by their high acidity (103-159 meq.g / Kg) while Baobab and Néré juices were characterized by their average fiber content (4-5.30 %). The juices of Baobab, Tomi and Néré are very rich in some minerals (K and Mg) but calcium (Ca) and iron(Fe) are not bioavailable (Oxales/Ca and Oxalates/Fe ˃ 2). The juice of baobab is rich in vit A (80 mg/100mL) and vit C (189 mg/100mL) than the others juices. Catechin was the most phenolic content (52.29-110.32 mg/100mL) where tartric acid was the most organic acid (4.02-6.82 mg/100mL) in the juices. The knowledge of the nutritional value of these juices could contribute to a better understanding of the essential role of these three wild fruits in terms of food and trade.

Aims: Produced in an artisanal way from the fermentation of the seeds of Parkia biglobosa, “Soumbala”, is a condiment very appreciated in several African countries including Côte d'Ivoire. This study was  conducted to assess the microbiological quality and fungal profile of this condiment sold in the markets of nine communes in Abidjan. Study Design: Food safety. Place and Duration of Study: Soumbala's samples were collected in the markets during the month of October 2019 and analyzed at the Laboratory of Microbiology and Food Biotechnology of the Nangui Abrogoua University, Côte d'Ivoire. Methodology: For this purpose, 27 samples of "Soumbala" were taken from the different markets and analysed. The loads of the different microorganisms (mesophilic aerobic germs, total coliforms, moulds) were determined by counting after culture in agar medium. The microbiological quality has been assessed according to Directive 2005/2073/EC. The physico-chemical composition (pH, titratable acidity, moisture content) of "Soumbala" has been determined according to standard methods. The identification of the mould strains isolated from the different samples was carried out using the identification keys. Results: The results of the various physico-chemical parameters obtained ranged from 13.81 to 20.31%, 5.58 to 6.50 and 3.73 to 9.06 % for moisture content, pH and titratable acidity, respectively. The mesophilic aerobic germ loads of 7.21 to 7.70 log10 cfu/g determined in the analyzed samples are above the acceptability limit (6 log10 cfu/g) applied in this study. The maximum loading of total coliforms was 3.92 log10 cfu/g. All mould loads are below the acceptability limit. The mould strains isolated and identified from the identification keys belong to the genus Aspergillus. Conclusion : A public health risk related to the consumption of "Soumbala" could exist if these moulds produced mycotoxin.

Background: “Soumbara” as well as other traditional foods of Côte d'Ivoire are produced in a traditional way. These foods may contain pathogenic and spoilage microorganisms. Aims: The aim of our work was to assess the sanitary quality of “Soumbara” sold in five communes of Abidjan (Côte d’Ivoire), in order to valorize it as a flavor enhancer. Material and Methods: A consumption survey as well as the analysis of some physico-chemical (pH, titratable acidity, Brix degree, moisture, and organic acids) and microbiological parameters (enumeration of MAG, Clostridium, Bacillus, Staphylococci, Salmonella, E. coli, and coliforms) were carried out in five (05) municipalities of Abidjan (Abobo, Yopougon, Port Bouet, Adjamé, and Treichville) on 75 samples. Results: The results of the survey showed that most of the respondents were familiar with “Soumbara” and often consumed it. These consumers stated that they did not experience any discomfort after consuming this food. Physicochemical analyses showed that the water content of the samples of “Soumbara” ranged from 16.50% to 19.28% and the pH varied from 6.32 ± 0.01 to 7.91± 0.02. “Soumbara” contained little follow-through which ranged from 0.10 ± 0.001 to 0.27 ± 0.05. “Soumbara” also contained phenolic compounds such as coumarins, hydroquinones, and caffeic acid. Microbiological analyses had revealed the presence of spoilage and pathogenic germs such as Bacillus, Staphylococcus, and E. coli at high loads exceeding the 2019/229/EC standard. Conclusions: However, due to the high load of spoilage and pathogenic microorganisms, this food eaten by sprinkling directly on the dish, without passing through a cooking process could expose the consumer to a risk of food poisoning. Keywords: Food poisoning, “Soumbara”, Pathogenic and Spoilage Microorganisms.

Cassava occupies an important place in the food security of populations in Côte d'Ivoire. There are many products derived from cassava but«attiéké» remains the flagship product in Côte d'Ivoire. Faced with the productivity challenges, organic fertilization is increasingly used by farmers in order to sustainably increase cassava production. The perspective of our study is to assess the effects of the uncombined use of cowpea and poultry manure as organic soil fertilizers on certain physicochemical and sensory characteristics of «attiékés» of three varieties of cassava. To do this, on an experimental plot installed, cowpea fertilization was tested at planting densities of 62,500; 250,000 and 125,000 plants/ha and poultry manure at rates 5; 15 and 5 t/haon, respectively, the cassava varieties Yavo, BoCou1 and Yacé.The results obtained show that cowpea and poultry manure increased the dry matter content respectively by 3.99 and 3.53 % in the Yavo variety by 3.57 and 18.06 % in the BoCou 1 as well as by 17.43 and 17.64 % in the Yacé. For the other parameters of pH, titratable acidity, total carbohydrates and free glucose, the variations depended on the variety and the level of fertilization. The sensory attributes of attiekes from these varieties grown on fertilized soil have been accepted by consumers in terms of color, smell, taste and consistency. In addition, they were rated less good than the controls obtained without fertilizer due to color, taste and consistency, while in terms of odor, it would be the same rating.

<p>Many standards constitute shea butter trading conditions, but the exploitation of this greasy product is submitted to other industrial exigencies. The aim of this study was to characterize and evaluate the utilization potentiality of the artisanal shea butter produced in Côte d’Ivoire, on the basis of the industrials exigencies. Hence, both beige and yellow artisanal (original and market) shea butters were collected and analyzed. The refractive indexes (1.46 ± 0.00) did not vary while specific gravity at 40 °C (0.86 ± 0.00 - 0.92 ± 0.00), unsaponifiable matter (1.80 ± 0.01 - 3.76 ± 0.02%) and pH values (5.39 - 6.69) showed significant differences from a sample to another. The viscosity was very high at 40 °C (86.78 ± 0.89 - 130.10 ± 0.26 mPas) and decreased with the temperature increasing (40 to 65 °C). The UV-Vis spectrum showed a very weak absorption from 300 to 400 nm (UV-B and UV-A domains) while the near infra-red (NIR) one, revealed peaks at 450 and 700 nm for yellow shea butters only and peaks at 1200, 1400, 1725 and 2150 nm for all the samples. The fatty acids profile highlighted four main fatty acids (palmitic, stearic, oleic and linoleic acids); saturated fatty acids (56.00 ± 0.20 - 63.00 ± 0.20%) were the most important. All these interesting characteristics should arouse attention for using traditional shea butters in food, cosmetic and pharmaceutical industries.</p>
