Aims: The study aimed to evaluate the nutritional and anti-nutritional factors composition of the Solanum torvum fruit. Place and Duration of Study: Department of Food Sciences and Technology, Biocatalysis and Bioprocessing laboratory of Nangui Abrogoua University (Côte d’Ivoire), between June 2019 and March 2020. Methodology: Proximate composition, mineral element profile and phytochemical composition of fresh and boiled S torvum berries were investigated. The S torvum fruit were harvested fresh. One part was cooked in boiling water for 25 min while the other part did not undergo any treatment. These two samples were dried in an oven at 45°C for 72 hours, ground and analyzed according to official analytical method. Results: The results indicated that the boiling caused the loss of nutrients except moisture, fibers and lipids. It was noted a significant reduction of nutrient and anti-nutrients content of berries after boiling. Boiled berries showed a higher energy value (57.07 Kcal) than fresh ones (53.12 Kcal). Despite the boiling, S torvum berries showed high levels of polyphenols (142.54 mg GAE/100g DW (dry weight)), carotenoids (12.96 mg βCE/100g DW), vitamin C (12.03 mg/100 g FW), fibers (6.88%) and ash (7.23%). Minerals analysis of S torvum berries indicated that it is rich in potassium (2046.77 mg/100 g DW), calcium (340.92 mg/100g DW), phosphorus (238.71 mg/100g DW) and magnesium (234.97 mg/100g DW) with high predicted bioavailability for calcium, magnesium and zinc. S torvum fruit contains also iron (7.97 mg/100g DW) and zinc (8.10 mg/100g DW) which are essential for organism. Conclusion: These data indicated that this Solanum torvum fruit consumed in East of Côte d’Ivoire could constitute a potential good source of nutrients for local population.

Impacts of cooking times (steaming and cooking on embers) on some physico-functional parameters of yam (D. bulbifera) flours cv Dougou-won were determined during 10, 20 and 30 min. Results showed that steaming and cooking on embers increased significantly (P <0.05) the dispersibility (D), water absorption capacity (WAC), paste clarity (PC), water solubility index (WSI), swelling power (SP), least gelation capacity (LGC) and solubility (S) but decreased significantly (P <0.05) foam capacity (FC), wettability (W) and foam stability (FS) of flours (D. bulbifera) cv Dougouwon. Steaming increased significantly (P <0.05) oils absorption capacity (OAC) and bulk density Ekissi et al.; ARJA, 10(4): 1-13, 2018; Article no.ARJA.44741 2 (BD). However, cooking on embers decreased significantly (P <0.05) oils absorption capacity (OAC) but not affected significantly (P <0.05) bulk density (BD). The steaming time (30 min) is recommended to considerably influence the physico-functional parameters of the yam (D. bulbifera) flours cv Dougou-won. Original Research Article
