Ferric-reducing/antioxidant power (FRAP) of green banana flour(GBF) extracts is 1.76 Fe(II) mmol/g dry basis. GBF extracts can scavenge 98% superoxide anion radicals generated by xanthine oxidase system (Table 4). Total polyphenol content and antioxidant capacity of the fried crackers with GBF of different substitution level is also depicted in Table 4. It can be observed that GBF substitution in the crackers increased the antioxidant capacity,which is important for prolonging the shelf life of the fried prod-ucts. The antioxidative activity in the crackers containing GBF maybe related with phenolic compounds present in GBF. A similarresult has been reported for the noodles containing GBF (Chong &Noor Aziah, 2010; Ovando-Martinez et al., 2009)
