Importance of proteins and mitochondrial changes as freshness indicators in fish muscle post‐mortem

Journal of the Science of Food and Agriculture, Volume 105, Issue 10, Page 5163-5172, 15 August 2025.
Abstract Evaluating protein and mitochondrial alterations post‐mortem can contribute to determining correlations between fish‐processing parameters and ultimate fish muscle quality. The myofibrillar protein alteration during rigor mortis directly affects the texture of fish muscle.
