Abstract

Pepsin-soluble collagen (PSC) from the skin of Nile tilapia (Oreochromis niloticus) was used for the obtention of collagen scaffolds, and their structural and physico-chemical properties were described. The PSC extraction yield was 18.3%, and the type I collagen was identified from it; the PSC scaffolds were successfully elaborated by electrospinning. The Fourier transform infrared spectrum confirmed that the triple helix structure was maintained before and after the electrospinning process. The differential scanning calorimetry analysis revealed high PSC temperature denaturation (38°C) and PSC scaffolds (30°C). These findings show that PSC can be an effective source of collagen for the PSC scaffold obtention and be further used as a potential biomaterial.
