Cashew Apple

In Côte d'Ivoire, cashew apples represent waste in plantations due to lack of processing. This study deals with their transformation into jam for a better valorization. Cashew apple jam were analyzed for physicochemical and sensory properties. Proximate physiochemical were determined using standard analytical procedures and the sensory acceptance test was performed by 50 panelists on the following attributes. Proximate result showed that moisture content of cashew apple jam was 26.5±1.77% ; carbohydrate 67.7±02.45%, protein 0.7±0.01%; fat and ash contents were 0.16±0.0 and 2.4±0.01% for respectively. pH and titratable acidity were 3.9±0.01 0.06% respectively. Soluble solids (°Brix) was 25±0.98%. Vitamin C and total sugar contents were 276±4.67 (mg/100g) and 51.87±2.18% respectively. Major minerals in the jam were potassium (2762±43.2 mg/Kg), phosphorus (298±4.1 mg/Kg), magnesium (146±1.1 mg/Kg) and calcium (143±2.21mg/Kg). phytochemical analysis revealed presence of tannins (0.8±0.01%), phenol (0.35±0.02%), oxalate (1.87±0.02%) carotenoids (0.70±0.01%), flavonoid (0.20±0.01%), phytate (1.16±0.03%) Results from sensory analysis showed color (7.88±0.55), consistency (8.22±0.83), sweet (8.44±1.09) odour (5.4±0.36) and general acceptability 5.22. Parameters (acidity, astringency and afteraste) scores are less than 3.

The ethnobotanical study carried out on the fruits of chilli (Capsicum annuum L.), type "Ahalimancou" in the localities of Aniassué, Affalikro, Sankadiokro and the town of Abengourou located in the east of the Côte d’Ivoire had for main objective to assess the levels of knowledge, the mode of use of this pepper by the local populations, as well as the phytochemical analysis of said chilli. Discussion groups and semi-structured individual interviews were carried out in 4 localities to collect information from 650 inhabitants, including 511 women and 139 men. The results showed that the variables gender, age group, ethnicity and level of education significantly influence (p≤0.05) the levels of knowledge and the mode of use, except the independence between the locality, the level of knowledge and mode of use. In addition, women know more about this type of pepper (80.82%) and use it much more in food (99.41%), as well as in the treatment of diseases (95.69%). People aged 60 and over have higher use levels (81.30%) in therapeutic use. The study also revealed that the Agni ethnic group is distinguished from other ethnic groups (Baoulé, Malinké, Attié) by a greater level of knowledge and use in pathology. Depending on the level of education, it appears that people without education know better (71.63%) and use this type of pepper more in the treatment of pathologies (85.39%). In addition, the study showed that the fresh form remains the only form used. With the exception of quinones, phytochemical analysis revealed that this type of pepper contains several pharmacological components depending on the stages of ripeness. Orange and red fruits had a higher content of alkaloids, polyphenols, flavonoids. The green and yellow fruits were highly rich in sterols and polyterpenes. Catechetical tannins were only present in green fruits. The data from our study could strengthen clinical research on the nutritional and pharmacological properties of this type of “Ahalimancou” chilli.

Fire Activity

Biomass burning has become more frequent and widespread worldwide, with a significant proportion occurring in tropical Africa. Fire dynamics have been generally studied at global or regional scales. At local scale, however, fire impacts can be severe or catastrophic, suggesting local analyses are warranted. This study aimed to characterise the spatio-temporal variations of vegetation fires and identify the main fire hotspots in Côte d’Ivoire, a country of West Africa, one of the world’s burn centres. Using MODISderived fire data over a 10-year period (2007–2016), the number of fire days, active fires and fire density were assessed across the entire country. In the southern part dominated by forests, fire activity was low. Three main fire hotspots were identified between 2°30’–8°30’W and 7°00’–10°30’N in the North-West, North-East and Central areas all dominated by savannas. In these areas, Bafing, Bounkani and Hambol regions recorded the highest fire activity where fire density was 0.4±0.02, 0.28±0.02 and 0.18±0.01 fires/km²/year, respectively. At national scale, the annual fire period stretched from October to April with 91% of fires occurring between December and February, with a peak in January. Over the decade, there was a decreasing trend of fire activity. Fire density also was negatively correlated with rainfall >1000 mm for the synchronic analysis, whereas fire density was positively correlated with rainfall in the previous years. Results suggest that the positive relationship between the previous year’s rainfall and fire activity could operate on a cycle from 1 to 4 years.

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.

The North-East region (Bounkani) of Côte d'Ivoire is the least watered region of the country with an average annual rainfall of 945 mm. The rainfall deficits observed in Côte d'Ivoire since 1970s could constitute a real threat to the environment and to water resources in general, and to dam lakes in particular. The main aim of this study was to follow the evolution of the dam lakes in the region over the years, i.e,(1986, 2002 and 2017) with reference to their spatial distribution (their densities and their limnological ratios). The approach adopted consisted of mapping and monitoring through remote sensing technology which involves processing satellite images for automatic extraction of these agropastoral structures on the various images. The results showed that these dam lakes were unevenly distributed both at the level of the departments and the watersheds, with 73.43% in the Black Volta and 28.57% in the Comoé. The density was higher in Doropo and varied from one department to another from 1986 to 2017, for the department of Bouna, it ranged from 9.34.10-4 to 3.74.10-3 per km2. The departments of Doropo and Tehini showed 1.51.10-3 to 1.01.10-2 per km2 and 1.05.10-3 to 4.53.10-3 per km2 respectively. Nassian department displayed a value of 1.42.10-3 per km2 and remained constant from 2002 to 2017. Like the density, Doropo Department had the highest limnological ratio which changes from 7.09.10-5 to 2.71.10-4 per km2 over the same period. The mapping of these agropastoral structures showed 18 agropastoral structures where 57 (28.07%) were functional or even contained water in the dry season in the region in 2017 including 2 in Nassian; 4 in Tehini; 9 in Doropo and 3 in Bouna.

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.

Based on an inquiry on the ground and geostatistics prossessing, this task analyses the problematic of aridity and the perception done by the peasant populations of the ‘’ North -East quarter’’ region of IVORY COAST. We come to know from these analyses that the dryness is a reality in this part of IVORY COAST. Indeed, starting with the indexes of NICHOLSON and MC KEE that is the test of PETTIT and the monthly climatic balance, agricultural and meteorological dryness have been determined to all the studied stations. Mainly the meteorological dryness is much more intensive in this sector of BOUNA and DABAKALA. As to agricultural dryness, it has been heavier in BOUAKE,KATIOLA, DABAKALA and BOUNA respectively. The test of FISHER has justified the variation of the dryness apprehension in the space. Thus, the dryness can be grasped by different ways (four ways) according to the inquired places. However, the peasant populations cannot distinguish the differences between meteorological and agricultural dryness clearly.

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.
