ABSTRACT This paper aimed to investigate whether the type of fish residue used for extraction of myofibrillar proteins (MP) impacts the technological properties of biodegradable films. The MPs were extracted from two types of Gilded cat-fish (Brachyplatystoma rousseauxii) residues: (1) carcass with muscle attached from the production of mechanically separated meat (MSM) and (2) parings from fillet trimming (PAR). The percentage composition and color of the MPs from MSM (P-MSM) and parings (P-PAR) significantly differed, mainly regarding the ash and lipid contents. The presence of these non-protein compounds in P-MSM led to the formation of films with inferior technological and thermal properties, which indicates the type of residue used impacted the film properties.
