Biotransformation of plantain pseudostem fibres using local enzyme sources; analysis of their potential as commercial poultry feed

Plantain pseudo-stem fibres (PPS) were valorized in this study by subjecting to simultaneous saccharification and fermentation (SSF) and afterwards, their complex carbohydrates and monosaccharides, mycotoxins, protein qualities, and free radical scavenging potentials were compared to those of commercial poultry feeds (CPF). The SSF of PPS was achieved using digestive juice of the snail; Archachatina marginata, and yeast, while standard methods like HPLC-UV, HPLC-DAD, monosaccharides and mycotoxin kits, and UV-VIS spectrophotometry were used for analysis. The cellulose, hemicellulose, pectin, lignin, extractives, and acetyl contents of PPS were significantly (p?1, B₂, G₁, and G₂), citrinin, fumonisin B₁, and B₂, ochratoxin A and B contents of SSF-PPS were equivalent to those for CPF. Patulin (5.52×10^?4?µg/kg) and zearalenone (7.76×10^?6?µg/kg) contents of the SSF-PPS were lower than those for CPF (1.50×10^?3?µg/kg and 1.13×10^?5?µg/kg respectively). The total amino acids (TAA), total non-essential and essential amino acids (TNEAA and TEAA), total basic and branched chain amino acids (TBAA and TBCAA) of the SSF-PPS were higher than those of the PPS and CPF while the free radical scavenging potentials of the SSF-PPS were mostly concentration dependent, and showed significantly higher ABTS, DPPH, Ferric, OH, lipid peroxide, and superoxide radical scavenging potentials than the standards used. This study has shown that the valorization of the agricultural residue using SSF, improves carbohydrate, protein, mycotoxins, and in-vitro antioxidant properties suitable enough for poultry feeding.
