Fecha de publicación: | 2022 | Editor: | Elsevier | Citación: | Food Chemistry: X 16: 100479 (2022) | Resumen: | Physicochemical, proteomics, and bioinformatics analyses were conducted to investigate protein profiles in Trichiurus haumela under frozen (120 d) and chilled (6 d) storage. Springiness, chewiness, myofibrillar active sulfhydryl content, and Ca2+-ATPase activity significantly decreased, suggesting that cold stress altered muscle proteins. Compared with fresh hairtail (FH), 66 common differentially abundant proteins (DAPs) had lower abundances in chilled (3 d; CSH) and frozen (120 d; FSH) hairtail, including myosin binding proteins, filamins, actinin, troponin, and muscle-restricted coiled-coil protein. Gene Ontology (GO) annotation showed DAPs were mainly involved in cellular process, cellular anatomical entity, intracellular, and binding items. Eukaryotic orthologous group (KOG) analysis revealed that changes in cytoskeleton and energy production and conversion functions dominated during cold storage, degrading the myofibril and connective tissue structures and the physicochemical performance of muscle tissues. This study presents deep insights into the protein alternation mechanisms in hairtail muscle under cold stress | Descripción: | 9 pages, 4 figures.-- Under a Creative Commons license | Versión del editor: | https://doi.org/10.1016/j.fochx.2022.100479 | URI: | http://hdl.handle.net/10261/282247 | DOI: | 10.1016/j.fochx.2022.100479 | ISSN: | 2590-1575 |
