Tanzanians challenged to invest in orange fleshed sweet potatoes

Scientists and researchers made the call when speaking at the just-concluded 8th Annual Sweet Potato for Profit and Health Initiative (SPHI) exhibition held in Dar es Salaam. Director general for the Commission for Science and Technology (Costech) Dr Hassan Mshinda said such potatoes can be used as an ingredient in baking to replace 20-60 per cent of wheat flour in baked products.
