Aims: This study aims to evaluate the physicochemical properties of palm kernel oil extracted from traditional varieties in the Mountain district, West region of Côte d’Ivoire. Study Design: Palm kernels were collected from women crude palm oil producers in three departments of the western part of Cote d'Ivoire. In each department, 50 kg of palm kernel were purchased per supplier. Place and Duration of Study: This study was carried out June to September 2017.The collected almonds of palm kernels were carried out at the Biochemistry and Food Sciences Laboratory of the Félix Houphouët-Boigny University, Abidjan. Methodology: The palm kernel oils were extracted by maceration and their physicochemical properties were determinate using standard methods. Results: The results obtained show that the values for the physicochemical parameters of palm kernel oils from the three departments were similar and fell in those of the standards of Codex Alimentarius 2019. However, physicochemical parameters statistically vary (P<0.05) between the departments. The yields of oils extracted fluctuated between 39.64 ± 2.14 % and 52.26 ± 1.16 %. The refractive index ranges between 1.453 ± 0.01 and 1.454 ± 0.002. The relative density varies between 0.90 and 0.91. The level of insoluble impurities ranged from 0.06 to 0.09 %. The moisture and volatile matter content varied between 0.62 ± 0.05 to 1.94 ± 0.07 %. The acid value and free fat acid percentage varies from 6.37 ± 0.65 to 8.54 ± 0.57 mg KOH/g and 3.20 ± 0.31 to 4.29 ± 0.28 %, the saponification value ranges between 216.02 ± 8.96 mg KOH/g and 248.16 ± 2.40 mgKOH/g, iodine value varies from 17.52 ± 0.43and 19.05 ± 0.95 g of iodine per 100 g of fat and peroxide value range between 6.02 ± 1.13 to 8.38 ± 1.00meq O2 kg of fat. The study of the lipid composition of these fats showed significant presence of fatty acid and unsaponifiable. The major fatty acids are lauric acid (50.50 - 51.00 %), myristic acid (18.35 - 18.80 %) and oleic acid (12.80 - 13.92 %). Conclusion: Given the results, palm kernel oils from the three departments exhibited good physicochemical properties, a clear indication that palm kernel oil could be used as edible and non-edible products in many homes and at various levels of industries in Côte d'Ivoire. There is limited information available about palm kernel oil from the western region of Côte d'Ivoire now and this study systematically researched on it, which can provide useful information for Ivorian oil palm industry.

In this work, comparative study of physicochemical properties and fatty acids of dried arils (DA) oil and those roasted (RA), of Blighia sapida from Côte d’Ivoire have been done using usual methods. The results showed that the crude fat obtained were 59.08± 0.02 g/100 g for dried arils (DA) and 60.51 ± 0.12 g/100 g for roasted arils (RA) respectively. Physicochemical properties of these oils were equal approximately, except level of saponification (241.19 mg KOH/g (DA) against 216.8 mg KOH/g (RA)); acid value (7 mg KOH/g (DA) and 6.28 mg KOH/g (RA)) and ester acid 234.19 mg KOH/g (DA) against 210.65 mg KOH/g (RA) where variances analysis showed that there was significant difference (p<0.05). On the other hand, refractive index, pH, moisture value, relative density and Free fatty acid were respectively; 1.465 (DA) and 1.475 (RA); 5.625 (DA) and 5.8 (RA); 1.757 (DA) and 1.9 (RA); 0.093 (DA) and 0.103 (RA), 3.52 mg KOH/g (DA) and 3.03 mg KOH/g (RA). The color of both oils was yellow. Fatty acid profile of these arils oils revealed that values of DA and RA were equal approximately (variances analysis showed that there was no significant difference (p<0.05)). These arils oils contained high levels of unsaturated fatty acids, 64.10 % (DA) and 65.17 % (RA), especially linolenic acid 20.02 mg/100 g (DA) and 22.18 mg/100 g (RA); linoleic acid 15.37 mg/100 g (DA) and 16.83 mg/100 g (RA) and Oleic acid 12.76 mg/100 g (DA) and 13.21 mg/100 g(RA). The saturated fatty Acids, accounted for 35.90% (DA) and 34.83% (RA) were constituted by palmitic acid with 18.02 mg/100 g (DA) and 18.11(RA) which were higher values. The values of stearic acid were 7.1 mg/100 g (DA) and 7.9 mg/100 g (RA) and 1.85 mg/100 g (AD) and 1.9 mg/100 g (RA) mg/100 g for myristic acid respectively. These results showed that the arils oils of Blighia sapida fruit from Côte d’Ivoire have highly nutritive fat content because rich in essentials fatty acids. These oils may be suitable for soap making and edible (margarine). The oils extracts exhibited good physicochemical properties and could be useful as edible oils and for industrial applications.

Les populations de la ville de Daloa en Côte d’Ivoire consomment majoritairement les eaux de forages au détriment de l’eau fournie par la société agréée. Ainsi, cette étude des eaux de forages a pour objectif l’évaluation de ses caractéristiques physico-chimiques. Elle a permis de mesurer au niveau de quinze forages les paramètres tels que le pH, la conductivité électrique, la température, le nitrite, le nitrate, l’ammonium, le sulfate, le bicarbonate, le calcium, le magnésium et le potassium. Les valeurs moyennes sont comparées aux normes relatives à la qualité de l’eau de boisson. L’analyse statistique multivariée dont l’Analyse en Composantes Principales (ACP) et la Classification Hiérarchique Ascendante (CHA) a été également appliquée à l’ensemble des paramètres mesurés. Il ressort des résultats que l’eau des forages est légèrement acide avec un pH moyen de 6,0 ± 0,5. Elle est faiblement minéralisée avec une conductivité électrique moyenne de 246,2 ± 162,6 μS/cm. Une forte corrélation est signalée entre la conductivité électrique et les paramètres suivants : nitrate, ammonium, bicarbonate, calcium, magnésium, sodium et potassium. La classification des forages est gouvernée par les valeurs de conductivité et de pH qui permettent de regrouper les forages selon leur qualité physico-chimique. Les eaux des forages de Daloa sont conformes aux directives de l’OMS.Mots clés : Daloa, eau de forage, norme, paramètres physico-chimique, qualité de l’eau. English title: Physicochemical characteristic of ground water for domestic use in the town of Daloa (Midwest, Ivory Coast)   The population of Daloa (third largest city in Côte d’Ivoire) mainly consume borehole water to the detriment of water provided by approved company. Thus, the quality of borehole water is evaluated from their physicochemical characteristics in this study. The study carried out in various districts of the city made it possible to measure for fifteen boreholes the physicochemical parameters such as pH, electric conductivity, temperature, nitrite, nitrate, ammonium, sulphate, bicarbonate, calcium, magnesium and potassium. The average values are compared with the standards relating to drinking water quality. The Multivariate statistical analysis whose Principal Components Analysis (PCA) and hierarchical clustering (HC) were also applied to the whole of the measured parameters. The results show that the borehole water is slightly acid with an average pH of 6,0 ± 0,5. It is slightly mineral-bearing with an average electric conductivity of 246,2 ± 162,6 μS/cm. A strong correlation is announced between electric conductivity and the following parameters: nitrate, ammonium, bicarbonate, calcium, magnesium, sodium and potassium. The classification of borehole controlled by this value of conductivity and pH which makes it possible to gather borehole according to their physicochemical quality. The physicochemical parameters of borehole water from Daloa are in conformity with the directives of WHO.Keywords: Daloa, borehole water, standard, physicochemical parameters, water quality.

Nutritional Potential

African eggplant Solanum aethiopicum var. striped toga is a vegetable-fruit widely consumed in Côte d'Ivoire. However, observations have shown that the cortex was removed from the pulp during culinary preparations for various reasons. The objective of this study is to contribute to the valorization of this eggplant by showing the nutritional interest of the cortex and the pulp. The samples used in this study were collected in a market garden located south of Abidjan. After separating the cortex from the pulp, they were ground into powder and used for physicochemical analysis. The results concerning physicochemical parameters showed that the ripe pulp (Pm) compared to the ripe cortex (Cm) contained more total sugars (165±0.7 versus 107±0.70 mg/100 g DM). Whereas, the unripe pulp Pnm contained significant amounts of polyphenols and tannins compared to the unripe cortex (636±0.25 versus 328±0.04 mg/100g DM for total polyphenols; 577±0.09 versus 171±0.21 mg/100 g DM for tannins). Oxalate contents decreased in ripe parts of the fruit (Pnm: 332±2.52 and Cnm: 131±1.00 mg/100g DM in unripe eggplant versus Pm: 157.75±1.52 and Cm: 55±0 .00 mg/100g DM in ripe eggplant). Also, Solanum aethiopicum var. striped toga could play an important role in human nutrition because of their nutrients content, thus contributing to better health.
