Several experiments with stressing and storage of cod under different temperature conditions have been carried out. The results show that cod can be stressed with a clear physiological stress response without effect on reduced quality. The interaction between handling stress and storage conditions show that the storage temperature and time were more important for the quality of the fish than the stress that the fish had been subjected to. Differences in protease activity between stressed and unstressed groups were found - this may be of importance for further processing of the fish. Significant differences in yellowness and hardness between control fish and stressed fish were found by a trained panel.
Goals:
(1) To determine the effects of handling stress combines with storage conditions on quality of farmed cod, and to determine which biochemical changes that are important for the resulting sensory quality; (2) Determine effect of handling stress on cod quality using several defined quality criteria Investigate possible interactions between handling stress and storage conditions; (3) Determine which proteins and protease activities that are important for the quality.
