Green bananaflour (GBF), as a functional ingredient, was used to partially substitute cassava starch intwo types of snacks, viz.fish cracker (FC) and cassava cracker (CC). It is observed that use of GBFincreased the nutritional value including enhancement of dietaryfiber, essential minerals, polyphenolcontent, antioxidant capacity and decreased oil content to varying degrees depending on the substitutionlevel in these two crackers. However, its use compromised the textural properties in terms of the linearexpansion ratio, crispness, bulk density, porosity and color. Sensory evaluation showed that the productswith not more than 40 g substitution level by GBF from 100 g cassava starch in CC and not more than 15 gin FC were acceptable by the panelists
