Mechanism on texture change of Wuchang bream (Megalobrama amblycephala) muscle during live transportation was explored by UPLC-QTOF-MS. The shear force (hardness) of fish muscle decreased gradually as the transportation time was extended from 3 to 24 h, with a maximum decrease of 43.49 %. With the extension of the time, the cellular and ultrastructure of fish muscle fiber were gradually disrupted. There was a significant difference between metabolites of the samples after transporting for 6, 12, 24 h versus 3 h, with organic acids and their derivatives upregulated while nucleotide metabolites downregulated. The texture deterioration might be related to metabolism of amino acids, purine, histidine, and choline. The results showed that the deterioration of Wuchang bream texture during live transportation might be mainly related to the changes of the above metabolic pathways caused by oxidative stress, which resulting in the destruction of the muscle cells and fibers.

4-Hydroxy-2-nonenal (HNE), a reactive compound produced during the peroxidation of polyunsaturated fatty acids, is implicated in numerous diseases and the degradation of food quality. Although the detection of HNE in meat has a long history, methods for detecting HNE in freshwater fish are inadequate due to the significant influence of matrix differences (i.e.

This experiment aimed to investigate the effects of emodin on the total bacterial count and immune response in various tissues of Wuchang bream infected with . The experimental diets were made by supplementing emodin at 0, 30, 100, and 150 mg kg to basal (control) diet, respectively, and fed to fish with an initial weight of 50.4 ± 2.

The broad application prospect of fish gelatin makes the traceability and identification of fish gelatin imminent. High performance liquid chromatography and high-resolution mass spectrometry (HPLC-MS/MS) was used to identify fish gelatins in seven commercial cyprinid fishes, namely, black carp, grass carp, silver carp, bighead carp, common carp, crucian carp, and Wuchang bream. By comparison with theoretical mammalian collagen (bovine and porcine collagen), the common and unique theoretical peptides were found in the collagen of grass carp, silver carp, and crucian carp, respectively.

To provide scientific support for improving the muscle quality of blunt snout bream, ultrahigh performance liquid chromatography, texture analyzer, and optical electron microscopy were applied to explore the effects of respite time (0, 24, 48, and 72 h) on the muscle quality of blunt snout bream before live transportation. The energy compounds (ATP and glycogen) of muscle significantly decreased with the respite time (p < 0.05).
