Evaluation of chemical and functional properties of fish mince Fish mince, made from cut-offs and frames from filleting processing, is often used as raw material for fish protein ingredients. The chemical and physicochemical properties of the material are therefore important. These properties can vary between species and are influenced by the treatment the mince has been through i.e. fresh or frozen. Fresh and frozen saithe mince made from cut-offs and frames were studied. Evaluations were made on chemical composition, water holding capacity and water mobility (T2 transversal relaxation times) of the fish minces. The fresh mince had slightly higher water content than the frozen mince. The water holding capacity was significantly higher (p
Figure 3.4 Water holding capacity of the fresh and frozen saithe mince produced from cut-offs and frames from filleting processing lines. Evaluation on the quality of fish protein isolate from rest raw materials of cod, saithe and Arctic char filleting process The quality attributes of fish protein isolates (FPI) made from rest raw materials (cut-offs) of filleting processes of cod (Gadus morhua), saithe (Pollachius virens), and Arctic char (Salvelinus alpinus) were determined based on the Codex Code of Practice for frozen surimi (FAO/WHO 2005). The results were compared to the attributes of conventional surimi and other fish protein isolates made from fish fillets. The results indicated that although quality attributes of these products, such as: gel strength, gel forming ability and whiteness were considerably different from conventional surimi, or FPI made from fresh fillets, it is still a good source of protein for manufacturing products which do not need a high level of gel strength, such as fish burgers, fish nuggets and other ready to eat fish products. The texture, taste and flavour of FPI products, which were produced in this study, were acceptable but they could be improved by adjusting different ingredients and spices according to the target market. Based on these results, the second study was performed. 31
