Abstract
The quality of food products from cassava are affected by processing
methods and varieties of cassava used which may later affect consumers demand. In this
work, fresh cassava roots of different local varieties (Odongbo, IITA funfun, Olekanga,
and Oko iyawo) were processed into gari and pupuru. The two products were analyzed
for proximate composition, mineral content, chemical and functional properties while
the reconstituted meals from them were evaluated for sensory properties. The highest
value of 2.13% crude protein was obtained for gari samples (Oko iyawo variety) while
the least value was 1.80% (odongbo variety). For pupuru, the highest value was 1.70%
(Oko iyawo variety) while the least was 1.52% (IITA variety). The cyanide content of
gari samples from Oko iyawo had the highest value of 4.08 mgHCN/kg while Olekanga
had the least value of 1.20 mgHCN/kg. For pupuru, Odongbo had the highest cyanide
content of 3.31mgHCN/kg and IITA had the least value of 2.63mgHCN/kg. The mineral
content showed that gari produced from IITA cassava varieties had the highest values in
terms of iron, Copper and Zinc for all the cassava varieties likewise for that of pupuru
except for magnesium where pupuru produced from oko iyawo cassava variety had the
highest value. Gari samples produced from Oko iyawo cassava variety were scored
highest in all the sensory parameters tested that makes the gari the most accepted
whereas that of IITA cassava variety had lowest scored. Also, pupuru produced from
Oko iyawo was scored highest in terms of taste and IITA cassava variety had lowest
scored in terms of aroma, flavor, overall acceptability and appearance. This shows that
gari and pupuru produced from IITA cassava variety were the least accepted.
