Starch is an important source of energy in human nutrition. It is also widely used as a processing aid in several food and non-food industries. Starch in wheat flour contributes to the development of optimal bread crumb and crust texture. It is also responsible for physical deterioration of bread quality through staling. Starch is mainly extracted from starch-rich plants such as cereals, root and tuber crops and legume... Read more.

Variable sensorial quality of attieké (a fermented cassava product like couscous) is mainly due to different types of artisanal starters used for fermentation of cassava dough. Biochemical properties of eleven lactic acid bacteria identified as Lactobacillus plantarum strains isolated from these traditional cassava starters were evaluated in vitro. Three of these isolates (Lp 210, Lp 140 and Lp 19) presented... Read more.

Despite enormous body of literature on household food insecurity and its determinants in the non-green belt of Ethiopia, such a research is scanty or nonexistent in the ‘green famine’ belt. The objective of this study was to examine factors determining household food insecurity in the ‘green famine’ belt of Ethiopia. Logistic regression model was employed to analyze the data collected... Read more.
