Characterisation of high added value compounds in wastewater throughout the salting process of codfish (Gadus morhua)
In Portugal Atlantic codfish (Gadus morhua) is dry-salted with food-grade marine salt for 6 days. During this process, codfish incorporates salt and drains away water up to 22%(w/w) of its weight, which contains important compounds, such as free amino acids, peptides and proteins. Hence, the chemica...
