Conclusions
Cooking loss of fish MP gel mediated by MTG at 1.8 g/100 g NaCl
was higher than at 2.6 g/100 g NaCl.
However, it could be reduced effectively by the addition of fish SP.
When fish SPwas incorporated with fish MP, the lightness and blueness of MP gel increased, while
the redness reduced.
Gel strength of MP mixed with SP at 1.8 g/100 g NaCl was higher than at 2.6 g/100 g NaCl.
The gel strength was not affected by the addition of 0.1 g/100 g SP, whereas a reduction of gel strength was observed for SP contents higher than 0.5 g/100 g.
In conclusion, application of fish SP at low concentration (1 g/100 g) could reduce the cooking loss of fish protein gel without negative effect on gel strength.
