Résumé

Effects of various freezing methods on the biochemical and physical properties of surimi, were examined. Stress values increased up to 3 months and then decreased. Strain values significantly decreased over time, except freeze-dried surimi stored at -18°C. Yellowness of the freeze-dried surimi stored at 22°C increased significantly during storage. In addition, salt-extractable proteins (SEP) decreased while dimethylamine (DMA) increased. Freeze-dried surimi showed the highest SEP and the lowest DMA values after 9 months of storage. At 6 and 9 months, development of proteins with smaller molecular weights was observed, indicating proteolytic degradation during frozen storage.
