Attribute #2:
OFSP is nutritionally superior to white-fleshed varieties
The results of the analysis of consumers WTP for
OFSP sweet potato-based biofortified biscuit are presented in Table 2 along with WTP for the dominant competing brand.
Implemented in drought-prone areas of Zambezia Province, where most households produce sweet potato but where nutrition is poor and Vitamin A intake is low, the programme promoted
OFSP, complemented by BCC messages and marketing.
Initial studies found positive responses in terms of people's consumption, and are currently being followed with programmes such as a USAID/HortCRSP project looking at how to incorporate sweet potatoes into more diverse food preparations--to improve economic welfare for farmers, processors, and others in the supply chain, as well as so boost
OFSP consumption (HortCRSP 2010, 2012).
The purpose of this study was to establish the effect of storing
OFSP roots under different conditions on their carotenoid content, microstructure and in vitro bioaccessibility.
Those low in zinc bioavailability (0-46%) were, fried African black nightshades, samosa, stewed green grams,
OFSP and tea.
[17] The nutritional composition of the
OFSP and the WFSP is shown in Table 1.
Most studies are currently focusing on nutritional and socioeconomic benefits of
OFSP but little effort has been directed towards enhancing food safety along the
OFSP puree value chain that has gained prominence in Kenya.
However, the Root and Tuber Improvement and Marketing Programme (RTIMP) and other partners have made tremendous strides at introducing
OFSP and other high yielding cultivars particularly with resistance to the sweet potato virus disease.
Also, that mentioned study found that orange-fleshed sweet potato (
OFSP) could make a major contribution to tackling vitamin A deficiency in affected countries where sweet potato is commonly consumed.
