Mango Juice

Mango seeds are discarded as waste after the extraction of mango juice. This study aims to valorise the kernels oils of mango (Mangifera indica). In this study, the kernel of four mango varieties (Amelie, Brooks, Kent and Keitt) that are grown and processing in north of Cote d’Ivoire investigated were used. The oils of these kernels were extracted by Soxhlet at 80 °C. Their physicochemical properties were determinate using standard methods. Physicochemical properties of the kernels oil were: specific gravity, 0.80±0.08 to 0.93±0.01; refractive index (50 °C), 1.43±0.07 to 1.47 ± 0.10; iodine value, 44.84 ± 0.05 to 59.41 ± 0.03 g I2 /100 g; peroxide value, 0.50 ± 0.00 to 1.90 ± 0.00 meq.O2/kg; acid value, 2.00 ± 0.00 to 7.65 ± 0.01 mg of KOH/g and saponification value, 167.53 ± 0.04 to 188.44 ± 0.04 mg KOH/g. Results revealed that these kernels oil contained a significant presence of oleic (31.14 ± 0.27 to 37.19c ± 0.23) and stearic (20.11 ± 0.12 to 40.43 ± 0.03) fatty acids. All these interesting characteristics confirm their usefulness for different nutritional and industrial applications.

Mango Peel

Mango almond and peel flours are a potential source of nutriment. In this study, the proximate composition and mineral element profile of four varieties of mango flour that are grown and processing in north of Cote d’Ivoire investigated. The data can be used as a reference when these flours are used for further processing in a variety of products. The peels and almonds were harvested fresh, dried in an oven at 50°C for 72 hours, ground and analysed according to standard procedures. Results showed carbohydrate, crude protein, total lipid, crude fibre, ash contents and vitamin C of the couple “peel – almond” flours were found to be 83.83-76.16%, 2.48-6.54%, 2.79-13.45%, 9.97-7.67%, 4.25-3.10% and a considerable amount of vitamin C of 307.67–304.85 mg/100g, respectively. They also contained important minerals such as calcium at 1204.45-1064.82 mg/100g, magnesium at 257.46-243.81 mg/100g, and potassium was the major at 1883.65-1617.66 mg/100g, regarding peels and almonds flours, respectively. Mangoes varieties such as Amelie, Kent, Keitt and Brooks have the potential to be a good source of nutrition for humans and animals.

Blighia Sapida

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.

Objective: The aim of this work was to determine the processing aptitude of maize varieties into food products to be promoted in Côte d’Ivoire. Methodology: Three dishes have been developed from ten maize varieties (MAAN16, PGBR, PGB18, AAA3, KF18, CJB, KO/Na4, KO/Na3, KO/Wa6, and EV99MRP). The sensory criteria used for the acceptability of the food products were the taste, the flavor and the color. Prior to the preparation of maize flour based food, like cakes, cooked flour paste (tôh) and semolina porridge,  the biochemical and physicochemical characteristics (moisture content, fat, protein content, ash content, carbohydrate, total sugar and reducers and pH) and functional characteristics of maize were determined. Hedonic   and descriptive tests were performed   with 30 and 15 panelists respectively. Results: The maize varieties presented good nutritional and technological potentialities because of their high content in essential compounds likely to influence the organoleptic characteristics of the processed food.  The lowest starch content was MAAN16 with 38.58 ± 0.45% dw and the highest was CJB with 71.85 ± 0.56% dw. The lowest protein content is 5.56 ± 0.17% dw at CJB and the highest protein content is 13.66 ± 0.33% dw in KO/Na3. The lowest fat content is 3.87 ± 0.12% dw (in KO/Na4) and the highest is 12.56 ± 0.50% dw (in MAAN16); the lowest carbohydrate level is 63.27 ± 0.01% dw (in MAAN16) and the highest is 74.92± 0.03% dw (in CJB). The acceptability of the cakes, the cooked flour paste and the semolina porridge depended on the maize variety. Foods prepared from maize varieties CJB, KO/Na3, KO/Wa6, MAAN16 and PGBR were the most appreciated by tasters.

Honey is a syrupy substance produced by bees, highly rich in monosaccharides (glucose, fructose), which give it a sweet flavor. In Côte d’Ivoire, there is very little information on the honey that is produced. The current work is to our knowledge the first of its kind. Its main objective is to assess the quality of the honey produced in nine localities in Côte d'Ivoire in terms of their physicochemical composition. All of the physicochemical characteristics (refractive index, total acidity, pH, viscosity, electrical conductivity and diastase index were within the limits established by the Codex Alimentarius Commission. The moisture content did not exceed 19.4%, which would indicate that the honey samples have long-term storage capacity and resistance to fermentation. The results were also distinguished by a high sugar content (78.60 - 83.80% of dry matter of honey), mentioning their maturity and nutritional value. In addition, the sucrose content was between 2.14 and 7.61%. Honey's total acidity index found between 7.50 and 24.20 meq/kg, is a proof of their bactericidal activity. The low HMF content (< 60 mg/kg) of most of samples taken reflects their good technological treatment and good quality. The content of fat (0.41 to 0.78 mg/100g) and protein (0.88 to 3.50%) certifies their acceptable nutritional qualities, with a significant energy value (from 396.39 to 402.70 kcal/100g of honey). Thus, the honey collected on Ivorian territory actually meets the requirements of the standards proposed by the Codex Alimentarius Commission.Keywords: Natural honey, physical parameters, physicochemical characteristics, nutritional properties, Côte d'Ivoire.
