This study aimed at determining the chemical composition and physico-functional properties of flour from Ivorian taro (Colocasia esculenta, cv yatan) corm as affected by boiling time. The change in boiling time led to a significant (p<0.05) reduction in the iodine affinity of starch, total carbohydrate, total phenolic compound, reducing and total sugars contents, whereas the moisture content, water absorption capacity, water solubility index, paste clarity and foam capacity increased significantly (p<0.05). The crude fat, crude fibre, crude protein and total ash contents were not affected by the change in boiling time. The flour of Ivorian taro corm is a good source of carbohydrate, fiber and ash. It contained a fair amount of crude protein and showed a high water absorption capacity and iodine affinity of starch. Within this flour, calcium, iron, sodium, zinc and copper had the lowest values while phosphorus, potassium and magnesium had the highest values. Significant correlations were observed between such constituents and physico-functional properties as moisture and water solubility index; crude fat and iodine affinity starch; total carbohydrate and paste clarity; total phenolic compound and forming capacity. PCA showed that FRTC was located at the left of the score plot, while FBTC20, FBTC35 and FBTC50 had a positive score in the first principal component. © Maxwell Scientific Organization, 2011.

The Tanoé-Ehy Forest, identified by the Centre Suisse de Recherches Scientifiques en Côte d'Ivoire (CSRS) as a top priority site for primate conservation in West Africa is prone to high anthropogenic pressures: poaching, uncontrolled harvesting of natural resources, logging and agricultural clearings. Unlike traditional policies of conservation of ecosystems characterized by the exclusion of local communities, a pilot program for community management of this forest was initiated in September 2006 with local residents. A good understanding of socio-economic and anthropological factors underpinning the relationships of the local communities with the forest is required to understand the determiners of success and sustainability of such a program. In a qualitative approach, with comprehensive, functionalist, and interactionist analysis tools, this study demonstrates how the existence of the Tanoé-Ehy Forest is crucial for the preservation of livelihoods for local residents and the maintenance of their sociocultural references. The study thus demonstrates that the conservation value of the Tanoé-Ehy Forest extends beyond the specificity of its biodiversity and finally gives clues for a proper consideration of the socio-anthropological dimension of the conservation of this heritage. © Didié Armand Zadou, Inza Kone, Vincent Kouassi Mouroufie, Constant Yves Adou Yao, Epiphanie K.

The search for new sources of oil with improved characteristics has focused our attention on the characterisation of Irvingia gabonensis seed kernel oil. Physicochemical analysis have revealed the following assets: refractive index (1.42 ± 0.00), free fatty acids (2.3 ± 0.8%), peroxide value (3.33 ± 0.57 meq O2/kg), iodine value (32.43 ± 1.22 g I2/100 g), saponification value (233.75 ± 2.60 mg KOH/g), unsaponifiable matter (1.5 ± 0.02%), carotenoids (63 ± 0.01 mg β-carotene/100 g) and phospholipids (2.1 ± 0.01%). Absorbance of this oil decreased abruptly in the range of UV-B and UV-A wavelengths. Gas chromatography analysis showed that the major fatty acids were saturated, being mainly composed of lauric (C12:0, 39.35 ± 0.01%) and myristic acids (C14:0, 20.54 ± 0.01%). Nevertheless, an unusually high amount (6.44 ± 0.02%) of linolenic acid was also noted. Mass spectrometer analysis of volatile compounds highlighted the presence of various aromatic and aliphatic organic compounds. I. gabonensis seed kernel oil also showed oxidative stability at 60 C after 12 days of storage with maximum peroxide value of 34.66 meq O2/kg. In view of these interesting characteristics, I. gabonensis seed kernel could be used as an alternative source of oil for lipid industries. © SAGE Publications 2012 [br]Los Angeles, London, New Delhi and Singapore.

Purpose: To investigate the seed oils of Corchorus olitorius and Hibiscus sabdariffa for their antioxidant and antimicrobial potential. Methods: The physicochemical characteristics of oil of the plant seeds were determined using standard methods while their volatile compounds were analyzed by gas chromatography coupled with mass spectrometery (GC-MS). The antioxidant activity of these oils was determined using 2,2-Diphenyl-1- picrylhydrazyl (DPPH) free radical scavenging method, and their antimicrobial effect was determined by agar dilution method. Results: Phospholipids, carotenoids and phenols contents of the studied seed oils were approximately 2.0 %, 100 mg/100g and 6.7 mg/100g, respectively. GC-MS analysis of the volatile compounds showed the presence of various aromatic and aliphatic organic compounds while the antioxidant activity of the oils was in the range of 0 to 5 g/l, which was higher than that of ascorbic acid. The seed oils also showed antimicrobial activity against Staphylococcus aureus, Aspergillus fumigatus and Trichophyton mentagrophytes with minimal inhibitory concentrations (MIC) of 250.0 and 62.5 mg/ml for C. olitorius and H. sabdariffa seed oils, respectively. Conclusion: C. olitorius and H. sabdariffa seed oils showed pronounced antioxidant and antimicrobial activities. These characteristics should be exploited for possible applications in the food supplement, pharmaceutical and cosmetic industries. © Pharmacotherapy Group, Faculty of Pharmacy, University of Benin, Benin City, 300001 Nigeria.
