Abstract
Banana flower (BF) and pseudostem (PS) are byproducts of banana cultivation and are known to have health beneficial effects. The main objective of this study was to evaluate the dietary fiber composition and antioxidant effect of BF and PS. In the present study, BF and PS were found to be rich in dietary fiber (65.6 ± 1.32 and 28.8 ± 0.98%, respectively). Dietary fiber fractions were extracted and characterized in terms of sugar profile, and antioxidant activities were determined. BF and PS fractions were rich in sugars and showed wide diversity with respect to the nature of the sugars. Hemicellulose A fraction of BF showed high amounts of total polyphenols and total antioxidants, which were 121.8 ± 1.9 and 39.03 ± 0.118 μg/mg extract, respectively. HPLC analysis showed the presence of phenolic acids in hemicellulose A and B fractions of BF. These results indicate that BF and PS are rich sources of dietary fiber associated with polyphenols, which could promote health beneficial effects.
