4. Discussion
This study investigated the effect of HP treatment on a range of
quality parameters in cod, mackerel and salmon and showed that
HP treatment affects both hardness, lightness and protein denaturation
in the different fish species. However, the effect on these
factors are not much affected by fish species, which suggests that
HP induced changes in structural proteins and thereby affects only
parameters like texture, lightness and water holding capacity, and
do not depend on amounts of fat or the muscle composition.
The effects of HP on liquid loss and water holding capacity were
minimal in all species, which may be caused by the severe
