Texture, Nutrition, and Flavor of Different Freshwater Fish Muscles: Comparative Study and Molecular Docking

Summary

This study provides a systematic comparative assessment of muscle quality attributes — including textural properties, nutritional value, and flavour characteristics — across multiple freshwater fish species. Molecular docking methods were applied to explore the mechanistic basis of flavour perception at a molecular level, likely examining ligand–receptor interactions relevant to taste or aroma. The findings contribute to evidence-based criteria for species selection in aquaculture and food quality assessment contexts.

UK applicability

The study focuses on freshwater fish species likely common to Chinese aquaculture and may not directly map onto UK-farmed or commercially relevant species such as trout or carp; however, the analytical framework and nutritional benchmarking methodology are broadly applicable to UK freshwater aquaculture and food quality research.

Key measures

Texture profile analysis (TPA) parameters; proximate composition (protein, fat, moisture, ash); amino acid and fatty acid profiles; flavour compound identification (e.g. free amino acids, nucleotides, volatile compounds); molecular docking binding affinities

Outcomes reported

The study compared physical texture, proximate and micronutrient composition, and flavour compounds across muscle tissues of different freshwater fish species. Molecular docking analyses were likely employed to investigate interactions between flavour-active compounds and relevant receptors or proteins.
