Quality changes of whitespotted conger (Conger myriaster) based physicochemical changes and label-free proteomics analysis during frozen storage.

ABSTRACT: Whitespotted conger (Conger myriaster) muscle proteins were susceptible to oxidative denaturation during frozen storage. The objective of this study was to investigate the alterations in quality through physicochemical analysis and proteomics after whitespotted conger stored at temperatures of -18 °C and -60 °C. The microstructural observation revealed the noticeable variations such as increased interstitial space and fractured muscle fibre with extension of frozen storage time, and the muscle fibre of whitespotted conger stored at -60 °C were more intact than those stored at -18 °C. The raised TVB-N value indicated that the freshness of whitespotted conger decreased during 120-day frozen storage period. Analysis of myofibrillar protein content and SDS-PAGE demonstrated that compare
