Mango Peels

Aims: This study aimed to quantify the bioactive compounds and the antioxidant activity of mango peels and kernels from two main varieties (Kent, Keitt) cultivated in Côte d’Ivoire. Study Design: Processing of mango varieties, determination of bioactive compounds content of mango peels and kernels, evaluation of antioxidant activity of mango peels and kernels. Place and Duration of Study: Felix Houphouet-Boigny University, Biotechnology Laboratory (March to September 2019). Methodology: Ripe mango (Mangifera indica L) fruits from Kent and Keitt varieties were processed to obtain peels and kernels powders. Methanolic extracts of peels and kernels were used to determine the content of phenolics, flavonoids and tanins while hexanic extracts were used to determine the content of carotenoids and phytosterols. DPPH scavenging and ferric reducing power tests were used to evaluate antioxidant activity of peels and kernels. Results: Total phenolics content of kernels of Kent (4371.22 ± 24.98 mg/100g dw) and Keitt (4037.93 ± 20.43 mg/100g dw) were higher (P ˂ 0.05) than those of peels from the two varieties (2564.37 – 3082.07 mg/100g dw). The values for carotenoids content of peels varied from 37.53 to 57.74 μg/g dw while those of kernels varied from 1.48 to 3.46 μg/g dw. Based on DPPH test The IC50 values ranged from 0.2 to 0.7 mg/mL with the highest antioxidant activity reported for kernels from Kent variety. The absorbance at 700 nm was found to be 0.4 for kernel of Keitt variety and 0.3 for ascorbic acid at a dose level of 0.03 mg/mL. Conclusion: Peels and kernels from Kent and Keitt varieties are potential sources of bioactive compounds especially phenolics, tanins, carotenoids and phytosterols. These valuable bioactive compounds in mango by-products may have greater application in the food, cosmetic and pharmaceutical industries.

Aims: The objective of this work was to contribute to the valorization of 3 local cucurbit oilseeds species grown in 2 producing regions of Côte d’Ivoire, namely the Kabadougou and the Moronou. Thus, a comparative study on the main nutritive and bioactive compounds of these cucurbits was conducted. Methodology: Mature dried seeds of Citrullus lanatus sp, Lagenaria siceraria Molina Standl, and Cucumeropsis mannii Naudin, locally named respectively Wlewle, Bebou and Nviele, were collected in the 2 regions, dehulled and processed for analyses. Standard procedures of AOAC, AFNOR and FAO were used for the determination of the nutritive and bioactive compounds. Results: Wlewle species exhibited the highest content of lipids (51.07±1.32%), energy caloric value (584.05±4.13 kcal/), polyphenols (141±23.97) and flavonoids (0.19±0.02) content. Nviele species had the highest protein (38.90±0.93%) and reducing sugar (70.62±1.03 mg/100 g) content. Bebou species exhibited the highest ash content (3.91±0.38%) and total soluble sugars (3.42±0.19%). Flavonoids content was similar for each species regardless of the region. Pearson’s correlation analysis revealed (p< 0.01) that energy caloric and lipid were directly correlated but conversely with protein. Direct correlation was also observed between polyphenols and lipid content in Wlewle and Nviele varieties, while in the Bebou, this trend was observed with protein. Despite their small shape, Wlewle species provide higher caloric energy upon consumption.

<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>

Sweet potato is an important food security crop in Sub-Saharan Africa. In Côte d’Ivoire, the roots are widely consumed as supplementary staple food or secondary food. The present study is conducted to highlight the nutritive composition, antinutrients and β-carotene contents of local sweet potatoes consumed in Côte d’Ivoire. The nutritive properties and antinutritive factors of these sweet potatoes were investigated using standard methods. Results confirmed the energetic value (363±1.63-374.08±0.56 kcal/100 g DM) of whole sweet potato flour, mainly due to its high carbohydrate content (86.75±0.40%-90.87±0.12%). Whole flour recorded low contents of moisture (4.50±0.10-6.30±0.15%), lipids (0.63±0.08-1.94±0.95%) and proteins (0.94±0.36-1.91±0.15%). The antinutritive factors ranged from 55.84±0.13 to 70.52±0.07 mg/100 g DM and 52.30±5.81-92.44±11.10 mg/100 g DM for oxalates and phytates, respectively. The mineral contents were: magnesium (49.37±1.09-540.87±0.82 mg/100 g DM), calcium (50.28±1.14-110.53±0.79 mg/100 g DM), phosphorus (25.12±1.04-42.75±0.82 mg/100 g DM), potassium (906.25±0.33-1625±0.61 mg/100 g DM), and iron (5.62±0.84-26.89±0.76 mg/100 g DM). The sweet potato flours highlighted polyphenols and antioxidant activity varying from 92.80±98.20±1.72 to 224.46±0.86 mg GAE /100 g DM, and 31.03±0.52-58.63±0.60%, respectively. While β-carotene levels of flours varied from 0.19±0.08 to 22.71±0.67 µg/g DM for white to orange cultivars. At the whole, the orange fleshed sweet potato cultivars recorded an appreciable amount of minerals (magnesium, iron and calcium), polyphenols and greater antioxidant activity. This indicates that these sweet potato cultivars may present a potential asset for their using as natural antioxidants to prevent chronic diseases and undernourishment caused mineral deficiency. The results also showed that the orange-fleshed varieties may contribute for vitamin A deficiencies alleviation in children of rural areas of Côte d’Ivoire.

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.
