Understanding cassava varietal preferences through pairwise ranking of gari-eba and fufu prepared by local farmer-processors
Within communities in Osun and Imo States of Nigeria, farmerâprocessors grew and processed a diverse set of improved and landrace cassava varieties into the locally popular foods, gari, eba and fufu. Local and 15 main varieties were grown in a 'mother and baby trials' design in each state. Mother trials with three replications were processed by farmerâprocessors renown in their community for their processing skills. Baby trials were managed and processed by other farmerâprocessors. The objective was to identify food quality criteria to inform demandâled breeding to benefit users, especially women, given their key roles in processing. Farmerâprocessors evaluated the overall quality of fresh roots and derived food products through pairwise comparisons. Improved varieties had higher fresh and dry root yield. Overall, landraces ranked first for quality of gari and eba, but several improved varieties were also appreciated for good quality. Landraces in Osun had higher gari yield and a higher swelling power compared to improved varieties. Colour (browning), bulk density, swelling power, solubility and water absorption capacity were the criteria most related to food product ranking by farmerâprocessors. Evaluation of varieties under farmerâprocessors' conditions is crucial for providing guidance to breeders on critical selection criteria
Effect of water yam (Dioscorea alata) flour fortified with distillers spent grain on nutritional, chemical, and functional properties
It was envisaged that the inclusion of treated distiller â s spent grain ( DSG ) to
yam fl our might increase its nutritional value, with the aim of reducing nutritional
diseases in communities consuming yam as a staple. Hence, yam fl our
was fortifi ed with DSG at 5â35%. The effects of this fortifi cation on the
nutritional, chemical, and functional properties of yam fl our were investigated.
The result showed a signifi cant increase ( P 0.001) in fat, ash, protein, total
amino acids, total dietary fi ber, and insoluble dietary fi ber contents of the blends
as DSG increased except for starch and soluble dietary fi ber contents, which
decreased. The functional properties showed a signifi cant ( P 0.001) reduction
with DSG inclusion. The inclusion of DSG increased both the tryptophan and
methionine contents of the blends. Therefore, the DSG fortifi ed yam fl our could
contribute to quality protein intake in populations consuming yam as a staple,
due to its indispensible amino acid content
