    The objective of this work was to determine the susceptibilities of starches from Nigeria’s high yielding local varieties of cassava and maize crops to α-amylase. Amylose/amylpectin content of each starch samples was determined. Susceptibilities to α-amylase were studied. The amylose/amylopectin content of the four starch samples varied; amylose content of starch from maize varieties was higher than those of cassava. Large differences in enzymes susceptibilities were observed when studied within 4 h with white maize having the highest value of dextrose equivalent of 42%, followed by yellow maize 37.5%, and cassava varieties, okoyawo 27.3% and odongbo 24.75%.Keywords: Odongbo, Okoyawo, α-amylase, amylase, amylopectin.African Journal of Biotechnology Vol. 12(29), pp. 4663-466
