Functional Properties and Rheological Behaviour of Haddock (Melanogrammusaeglefinus) Protein Isolates under Various Storage ConditionsAbstract:Fish protein isolates (FPI) were extracted from haddock (Melanogrammus aeglefinus)cut-offs using the pH-shift method. Fresh and frozen stability and rheological behaviour ofhaddock protein isolates (HPI) containing 20% protein (pH 6.4) and different amounts ofsalt and sucrose and also polyphosphate stored at +2, -18 and -24˚C were studied. Theresults indicated that in fresh FPIs added salt and sucrose to the test samples increasedWHC, but significantly (p0.05) but it decreased Brabender viscosity(P
