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

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....

Analysis of different extraction solvents: Influence on some properties of aerial yam (Dioscorea bulbifera) starch

Starch was extracted from aerial yam (Dioscorea bulbifera) using water, sodium hydroxide, ammonium oxalate, and oxalic acid as extraction solvents, oven-dried at 45°C for 24 h, and milled to flour. The starch obtained was evaluated for yield, chemical and functional properties using standard procedures. The sensory attributes of the starch cooked pastes were also determined. Aerial yam extracted with oxalate gave...
