Abstract

In order to improve the properties of myofibrillar protein-based film from silver carp (Hypophthalmichthys molitrix), nanofibrillated cellulose (NFC) at 3 levels (1, 3 and 5%) was used. Optimum treatment was determined by evaluating the mechanical, physical and optical properties as well as scanning electron microscopy analysis (SEM). Cellulose nanoparticles had no effect on tensile strength but reduced the elasticity of film (p≤0.05). Water vapor barrier property (WVP) and other physical properties of the films were improved by addition of nanofibrillated cellulose at 1%, but decreased at higher concentrations (p≤0.05. Based on SEM, low concentrations of nanoparticles showed more homogeneous dispersion and films had a smoother and better cross-sectional area compared to the higher levels of nanoparticles. Generally, low levels of nanoparticles could be effective to improve the mechanical and physical properties of myofibrillar protein - nanofibrillated cellulose films.
