The myosin heavy chain partially disappeared, suggesting the formation of cross-linked proteins.
The gel strength of MP was not affected by the addition of 0.1 g/100 g SP (P > 0.05) whereas it started to decrease when SP was added up to 0.5 g/100 g, regardless of the NaCl concentration.
The cooking loss of the MP gel was reduced efficiently when SP was added,
even at a low concentration (0.1 g/100 g).
A further reduction of cooking loss was observed when SP concentration was increased.
The smooth microstructure of the gel surface was observed in samples containing SP,
showing the lower cooking loss
of fish myofibrillar protein gel.
