  ABSTRACT: Sweet potato (Ipomoea batatas) is one of the most important, versatile and unexploited crops in Kenya. The crop is well adapted to smallholder farming systems, inexpensive to produce, relatively drought tolerant and gives high yields even with minimum inputs. Although widely produced in Kenya, sweet potato remains primarily a subsistence crop. Lack of organized marketing, limited consumer interest and low value addition activities are some of the factors that have contributed to low commercialization of the crop. The overall objective of the current study was to investigate the suitability of incorporating sweet potato leaves into the roots to produce nutritious sweet potato flakes with high vitamin A and protein content. Sweet potato roots were cured to increase the endogenous amylase enzyme and then washed and pre-cooked to enable starch hydrolysis to increase sweetness of the flakes and then heated to boiling to enable mashing. Dried sweet potato leaves powder was then added to the mash sweet potato roots at varying percentages and then dried using single drum drier. Addition of sweet potato leaves was found to significantly (p
