In terms of texture properties, post-mortem hardness, cohesiveness, elasticity, chewiness and gumminess were decreased day by day, whereas stickiness, Fmax, Fmin and Fmax-Fmin were significantly increased (p <.05). According to SDS-PAGE results, a decreased value on MHC was determined (p <.05). Texture properties and SDS-PAGE results were found different among groups (p <.05). Correlation between chewiness, gumminess, MHC and hardness; between chewiness and gumminess; between Fmin, Fmax-Fmin and Fmax; between Fmin and Fmax-Fmin were significant. As a result of the study, S. fontinalis exhibited least deterioration in comparison with other species and it was determined that SDS-PAGE results and texture properties support each other.trueMHC | myofibril protein | SDS-PAGE | texture | troutArticle10.1111/are.142812-s2.0-85070073414
