In order to determine the physicochemical and organoleptic indicators of orito banana (Musa acuminata AA) rachis, treated with whey, a completely randomized design was applied with seven treatments: natural (control) and fermented (0, 1, 4, 8, 15 and 30 d). Results showed the highest (P <0.05) pH values on day zero (4.91); crude protein on days eight (16.12 %), 15 (16.07%) and 30 (16.07 %); total phenols on day 30 (323,361.91 μMol GAE/100 g DM) and antioxidant activity on day eight (29,595.62 μMol TROLOX/100 g DM). Silage had a sweet smell (days zero and one) and a mild acidity (days four, eight, 15 and 30). It showed a light brown color and solid consistency. It is concluded that, through orito banana rachis fermentation, improvements were achieved for contents of crude protein, total phenols and antioxidant activity, which makes possible to obtain a functional food that can be used for animal feed.
Key words: animal feed, fermentation, total phenols, banana residues
