Despite the large scale production of commercially processed
products of sweet potato in several countries of the world, agroprocessing
of sweet potato in South Africa is limited to producing frozen
vegetables (roughly 2000–3000 tons) while small volumes (roughly
500–1000 tons) are dehydrated (DAFF, 2011). There is a vast scope for
stimulating production and reducing post-harvest losses through
agro-processing of biofortified sweet potato. Sweet potato can for example
be dried/dehydrated (e.g. flour, flakes, chips), frozen (e.g. French
fries), canned (e.g. baby foods) or used as an ingredient in confectionary
and bread (Oke & Workneh, 2013).
