Stability and cytotoxicity of DPPH inhibitory peptides derived from biodegradation of chicken feather

The antioxidant activity and cell viability of feather hydrolysates obtained with the Bacillus licheniformis were evaluated using an in-vitro model. results indicate that feathers-derived peptides under 3 kDa have IC50 values 5.03 ± 0.215 mg/mL by DPPH assay. Although preserved after applying diverse heating (from 20 to 100 °C), they lost their strongly acidic or alkaline conditions. Antioxidant mixed bioactive (MFBPs) partial purification was amount 0.169 0.004 radical scavenging Also, MFBPs within range from 0.0048 5.0 mg/mL, illustrated no cytotoxicity gingival fibroblast blood lines. In light our results, value-added could be useful in different food products as a future functional ingredient potency.
