Phytate degradation in composite wheat/cassava/sorghum bread: Effects of preincubation of Pichia kudriavzevii TY13 and presence of yeast extract

December 2022

Diet based on whole cereal flours is associated with a high prevalence of iron deficiency anemia and zinc deficiency in low/middle-income countries. Such flours contain high content of phytate that chelates minerals such as iron and zinc, making them unavailable for absorption by humans. To improve the mineral absorption, a phytate:iron molar ratio <1 and a phytate:zinc molar ratio <5 is needed to be achieved....

Physicochemical parameters of Blighia sapida (K.D. Koenig) oil extracted in Togo

October-December 2022

Oils extracted from Blighia sapida fruits are usually consumed without any information on its chemical composition. However the bad quality of oil can be a source of toxicity. Thus, the aim of this study is to investigate the physicochemical quality of the oil extracted from B. sapida from Togolese flora. To reach the goal of the study, mature and immature of B. sapida arils were used for oil extraction by the solvent...

Variation of some growth, agronomical and biochemical parameters of Vigna unguiculata (L. Walp) under salinity stress

November, 2022

The variation of some growth, agronomical and biochemical parameters of Vigna unguiculata (L. Walp) under salinity stress were investigated in the greenhouse and farm conditions. Plants were subjected to 0, 50, 100 and 200 mM NaCl. The increases of NaCl in the culture medium significantly (P< 0.001) decreased the growth parameters (number of leaves, noose diameter, leaf area and stem height), dry biomass (roots,...

Increasing soil condensation capacity for agricultural purposes

November 2022

The issue of water scarcity in many parts of the world, especially in arid and semi-arid regions, is a major dilemma. The amount of moisture for plants is not comparable to rain, but in arid areas, it is a huge contribution to plant water supply. In this research, the effect of using Peltier to improve soil condensation by performing several tests was studied in order to investigate the possibility of increasing soil...
