Cassava (Manihot esculenta Crantz) has been considered
to be the major human food crop with a high
content of cyanogenic glycosides (Osuntokun, 1969).
Cassava roots form the important staple food for more
than 500 million people (Brocas, 1987) mostly in the
tropical countries such as Africa, Asia and Latin
America. Nigeria is one of the world’s largest producers
of cassava and it has been estimated that about 70% of
the cassava grown in Nigeria is channeled into ‘gari’
manufacturing (Olayide et al., 1972).
