Physiochemical and nutritional characterization of Vitex payos (Lour.) Merr. (Verbenaceae): An indigenous fruit tree of Eastern Africa

October 2012

In the dry areas, indigenous fruits become important staples when cereals harvested are inadequate to support populations. Farmers in these areas have identified many of the handicaps in domestication but there is still need for inputs from the food industry into identification of the desirable traits and characteristics of potentially novel food. The purpose of this study was to assess the nutrient content of one...
