Chemical and LC-MS-based lipidomics analyses revealed changes in lipid profiles in hairtail (Trichiurus haumela) muscle during chilled storage.

Chemical and liquid chromatography-mass spectrometry (LC-MS)-based lipidomics techniques were used to investigate the alternations of lipid profiles in hairtail (Trichiurus haumela) muscle after chilled storage for six days. The chemical results showed that the peroxide values (PVs) and thiobarbituric acid reactive species (TBARS) content in the muscle increased significantly, from 0.43 meq/kg of lipids and 0.

Investigation of the changes in the lipid profiles in hairtail (Trichiurus haumela) muscle during frozen storage using chemical and LC/MS-based lipidomics analysis.

Chemical and LC/MS-based lipidomics strategies were performed to explore the alterations of lipid profiles in hairtail (Trichiurus haumela) muscle during 120 days of frozen storage. Chemical results indicated that the PV and TBARS values in hairtail muscle significantly increased during 120 days of frozen storage. Lipidomics results detected 1223 lipids in hairtail muscle assigned to 26 lipid categories, including 261 triglycerides (TGs), 251 phosphatidylcholines (PCs), 153 phosphatidylethanolamines (PEs), and 66 diglycerides (DGs).

Effect of kappa-carrageenan oligosaccharides on myofibrillar protein oxidation in peeled shrimp (Litopenaeus vannamei) during long-term frozen storage.

Protein oxidation during chilling and frozen storage has recently attracted great attention due to its consequences on protein solubility and functionality. In this study, the effects of kappa-carrageenan oligosaccharides on myofibrillar protein oxidation in peeled shrimp (Litopenaeus vannamei) during frozen storage were investigated by assessing the content of the carbonyls, total sulfhydryl, dityrosine, and surface hydrophobicity. We also examined the means of antioxidant activity in vitro, degradation of muscle proteins, and integrity of tissue structure.

Depuration of Cadmium from Blue Mussel (Mytilus edulis) by Protein Hydrolysate-Fe Complex: The Role of Metallothionein.

Unlabelled: Metallothionein (MT) plays a major role in the detoxification of toxic metal ions in mussel. This study served to investigate the effects of prepared protein hydrolysate-Fe (PH-Fe ) on depuration of cadmium salt (Cd ) from blue mussel (Mytilus edulis). The results indicated that Cd concentrations in control ranged from 46.
