From the present investigation it can be concluded that the nutritional value of the fish cracker (FC) and cassava cracker (CC)can be enhanced by green banana flour (GBF) substitution for cassava starch. Crackers containing greater amount of GBF showedincreasing antioxidant capacity including Ferric-reducing power and superoxide radical scavenging capacity. Although use of GBF compromised the textural properties of these crackers, the prod-ucts with not more than 40 g substitution level by GBF from 100 g cassava starch in CC and not more than 15 g in FC were found acceptable by the panelist. Further investigations should be per-formed to evaluate the quality change of these crackers during storage and the effect of GBF substitution on protein digestibility.
