Abstract: | The freezing of sardine mince gels produced slight alterations in texture, microstructure and degree of chemical aggregation of proteins, irrespective of freezing temperature (– 18°C or – 40°C). The most noticeable changes took place during frozen storage 3 mo, particularly in gels frozen at – 18°C which were strongly affected by storage temperature (– 12°C or – 18°C), unlike those frozen at – 40°C. Better gel integrity was found in those frozen at – 40°C, where cavities were more numerous, but smaller and more evenly distributed than in gels frozen at – 18°C. |
