Six okra varieties (F1 Yodana, Kirikou, Volta, Yeleen, Kousko and Local) sold and consumed in Daloa (Côte d’Ivoire) were evaluated with regards to the nutritional, antioxidant and mineral contents. The result of the study revealed that the proximate composition in dry weight basis was significantly (P < 0.05) varied and ranged: dry matter 87.83-92.33%, crude protein 13.65-22.63%, crude fat 2.78-3.94%, crude fiber 21.08-26.70%, crude ash 7.16-10.59%, carbohydrate 39.28-54.25%, and energy value 274.78-297.97 kcal/100 g. Volta had the highest content in both protein and fat. Yeleen had the highest ash content, Local had the highest fiber content, while Kirikou presented the highest content in both carbohydrate and energy values. The phenolic content ranges from 111.42 to 156.00 mg/100 g while the vitamin C ranges from 25.30 to 49.60 mg/100 g in dry weight basis. Volta had the highest content in both phenolic and vitamin C. The mineral contents (mg/100 g) in dry weight basis were also significantly (P < 0.05) varied. Potassium was the most abundant macro-element (1642.71-2519.84) followed by calcium (460.80-767.72), magnesium (345.46-432.70) and Iron (0.42-3.18) in all the varieties. Interrelationships between the parameters analysed and the different okra varieties were investigated by principal component analysis (PCA). PCA revealed differences between the okra varieties and classified them into three groups on the basis of the measured parameters: Group 1 (F1 Yodana, Volta and Local), Group 2 (Kirikou and Kousko) and Group 3 (Yeleen). This study provided important information about the nutritional composition of okra from Daloa, which can help to increase production and consumption of these nutrient-rich vegetables and will help reduce the nutrition-related disorders in Africa.

Mushroom cultivation has been started in Côte d’Ivoire. Awareness of the nutritional and medicinal importance of mushrooms is not extensive. In this study, the nutritional values of dietary mushrooms Pleurotus ostreatus, that are very popular among the cultivated mushrooms in Côte d’Ivoire have been determined. The samples were obtained and analysed for proximate, mineral, vitamin, amino acids and fatty on dry weight basis using standard methods. These mushrooms were rich in minerals content (Cu= 36.35% ; Iron= 52.65 % ; Magnesium= 47.84 % ; Sodium= 14.50%) and contained a lower amount of calcium (9.85%), phosphorus, potassium, and zinc. We also note the presence of vitamin A (0.19%), vitamin C (17.48%) and those of group B (B1, B2, B3, B6 and B9). The amino acids contents ranged from 1.17% for alanine and lysine, 1.7 % for leucine and 0.07% to serine. The mushrooms are rich in lipid with the presence of linoleic acid, linolenic acid, oleic acid, palmitic acid and stearic acid. Data of this study suggest that mushrooms are rich in nutritional value.

Aims: The study aimed to evaluate the nutritional and anti-nutritional factors composition of the Solanum torvum fruit. Place and Duration of Study: Department of Food Sciences and Technology, Biocatalysis and Bioprocessing laboratory of Nangui Abrogoua University (Côte d’Ivoire), between June 2019 and March 2020. Methodology: Proximate composition, mineral element profile and phytochemical composition of fresh and boiled S torvum berries were investigated. The S torvum fruit were harvested fresh. One part was cooked in boiling water for 25 min while the other part did not undergo any treatment. These two samples were dried in an oven at 45°C for 72 hours, ground and analyzed according to official analytical method. Results: The results indicated that the boiling caused the loss of nutrients except moisture, fibers and lipids. It was noted a significant reduction of nutrient and anti-nutrients content of berries after boiling. Boiled berries showed a higher energy value (57.07 Kcal) than fresh ones (53.12 Kcal). Despite the boiling, S torvum berries showed high levels of polyphenols (142.54 mg GAE/100g DW (dry weight)), carotenoids (12.96 mg βCE/100g DW), vitamin C (12.03 mg/100 g FW), fibers (6.88%) and ash (7.23%). Minerals analysis of S torvum berries indicated that it is rich in potassium (2046.77 mg/100 g DW), calcium (340.92 mg/100g DW), phosphorus (238.71 mg/100g DW) and magnesium (234.97 mg/100g DW) with high predicted bioavailability for calcium, magnesium and zinc. S torvum fruit contains also iron (7.97 mg/100g DW) and zinc (8.10 mg/100g DW) which are essential for organism. Conclusion: These data indicated that this Solanum torvum fruit consumed in East of Côte d’Ivoire could constitute a potential good source of nutrients for local population.

Vitex Doniana

Black plum, the fruit of Vitex doniana, was harvested in three (3) regions belonging to different climatic zones in northern Côte d'Ivoire. Biochemical characteristics of the pulps were studied in order to highlight their nutritional potential and the variability of this composition according to study areas. From the conventional biochemical analyzes used, it appears that the fruit pulp is acidic and mostly made up of water. It is rich in sugars and has antioxidant power between 18.63 ± 0.02 and 35.54 ± 0.01 µg.mL -1. There is also the presence of polyphenols (166.67 ± 0.01 – 196.67 ± 0.01 mEq A.G./100g) and vitamin C (14.34 ± 0.02 – 15.05 ± 0.07 mg/100g). Ashes consist of minerals such as magnesium, potassium and calcium. The analysis of the variance showed that the mean of the parameters studied are significantly different from one region to the other, except the ash rate and vitamin C content. In view of its nutritional quality, black plum presents itself as an interesting fruit to be taken into account in the prevention of certain dietary imbalances and which can even intervene at low cost in the treatment of certain pathologies.

Food and feeding behavior of P. leonensis was studied by analyzing the stomach contents of 864 individuals caught in the two main catchment areas in Taabo Lake, notably, at Taabo city and Antonio. Food items data were analyzed by using the three following methods: Relative Importance Index (IRI), Food Index of Geistdoerfer (Q) and Principal Component Analysis of Occurrence Index. The results of our study showed, that P . leonensis is zooplanktonophagus. Its diet also includes Diptera (Ceratopogonidae, Chaoboridae), Ephemeroptera (Baetidae, Libellulidae), Trichoptera and Hymenoptera (Formicidae). The Food Index of Geistdoerfer indicates, that the diet of this Fish species is composed of two main preferential preys: Copepods and Cladocerans. Furthermore, Chironomidae are frequent secondary preys and the others items are secondary order complementary preys. At least, the results of the principal component analysis of items occurrences show, that the prey frequency is function of P. leonensis catchment area or sub-area in Taabo Lake, and evolve inversely, according to climatic seasons. © 2019 International Formulae Group.

The great diversity of agroecological factors that cover the yam production area in Côte d’Ivoire can be a source of morphological variability within Scutellonema bradys species, responsible for yam dry rot. This study aims at identifying the morphological group(s) of S. bradys which infect(s) yam Dioscorea cayenensis-rotundata. Two hundred ten yam tubers for sale in food markets in the Autonomous District of Abidjan were sampled from traders. After extraction and identification, a morphological characterization was carried out on S. bradys populations using morphological descriptors. Yam tubers sampled from food markets came from three agroecological zones namely dry tropical savannah, semi-deciduous dense forest and transitional forest areas. Morphometric variables and ratios used individually did not help identify morphological groups. Principal component analysis, however, performed with the most discriminating variables and ratios revealed three morphological groups named "large", "medium" and "small" in males and females and confirmed by the agglomerative hierarchical clustering. Each group consisted of a rate greater than 48% of individuals from a given agroecological zone. Three morphological groups of S. bradys are associated with yam dry rot in Côte d’Ivoire. Pathogenic and molecular characterization of the morphological groups would be necessary with a view to researching control methods.

The aim of this study was to evaluate the chemical composition and mineral bioavailability of T. tetraptera fruit pulp, an aromatic wild edible plant, using standard methods. The pulp were extracted from mature dried fruits obtained from plants at Awabo (5°30’14.2”N and 4°01’30.6”W) and Loviguié villages (5°48’24.5’’N and 4°20’15.8”W), all in south-eastern Côte d’Ivoire. The results of chemical analysis revealed that T. tetraptera fruit pulp contains carbohydrates (63.73±0.51%), crude protein (7.01±0.66%), crude fat (1.18±0.01%), ash (5.38±0.18%), fibre (11.78±0.02%), moisture (40.52±0.18%) and an energy value of 254.74±0.15 kcal/100g. Besides, the results showed a relative high amount of vitamin A (2.11±0.02%) and vitamin B9 (261.78±0.01 µg/100g) while vitamin E, B1 and B2 in trace concentration. Otherwise, the phytochemical analysis (mg/100g) based on dry weight revealed an appreciable amount of total phenol (2407.10±8.36), flavonoids (14.29±0.56), tannins (55.11±0.44), catechin (392.93±1.01) and also carotenoids (108.19±7.42 µg/100g). Organic acids profile (mg/100mL) showed citric acid (175.06±0.02) and salicylic acid (109.85±0.01) as major organic acids. Mineral composition (mg/100g) on dry weight basis revealed that potassium (1303.67±0.58) is the most abundant followed by phosphorus (303.33±5.77), calcium (187.33±0.58) and magnesium (141.33±0.57). Furthermore, the Phytates:Zn, Phytates:Ca, Oxalates:Ca and Phytates*Ca:Zn molar ratios recorded were all below than recommended threshold values, implying a bioavailability of zinc and calcium. These data indicate that the pulp of this fruit could be a good source of ingredient for both medicine and food industries in production.

Bacterial disease is a major biotic constraints of mango production in Côte d'Ivoire. The objective of this study is to assess the distribution of mango bacteriosis disease in mango production areas in northern Côte d'Ivoire. This study focused on 720 mango trees, of the Kent variety, spread over 20 orchards. These orchards are located in the Bagoué, Tchologo and Poro regions in northern Côte d'Ivoire. The study consisted of determining the incidence and severity of bacterial disease on the leaves and fruits of mango trees. Data on the incidence and severity index of bacterial disease on leaves and fruits were subjected to descriptive analysis followed by PCA. Then, the ascending hierarchical classification (CAH) and multivariate analysis completed the data analysis. The results obtained did not reveal any dissimilarity of the presence of the bacterial disease in the three (3) regions studied. On the other hand, a predominance of the severe or major type of bacterial disease over the level of slight or marginal contamination has been demonstrated. None of the three main regions (Poro, Tchologo and Bagoué) of mango production in Côte d'Ivoire appears to be the center of bacterial disease dispersion at the current stage of bacterial disease progression. The level of incidence and severity of this disease is similar between fruits and leaves. The Principal Component Analysis and the Ascending Hierachical Classification completed by the MANOVA made it possible to structure the mango orchards into three (3) homogeneous groups. Group 2 orchards (VB4, VB8, VB7 and VF2) presented a moderate level of incidence and severity on leaves and fruits.
