High inhibition of linoleic acid peroxidation indicates a high antioxidant activity. Noodle 30BFN, which exhibited the highest inhibition, was significantly (p < 0.05) higher than were conG and conN but not different from (p > 0.05) 30BFG (Table 3). The significantly higher antioxidative activity in BF-incorporated noodles was attributed by the higher content of the TP and the strong antioxidative ability of phenolic compounds present in BF. Inhibition of linoleic peroxidation in noodles was also increased by addition of 10% oat b-glucan. However, the antioxidative ability is not as great as in BF. This is because oat (caffeic and ferulic acids) has only a weak antioxidative activity (Osawa, Ide, Su, & Namiki, 1987) compared to banana.
