Fresh Chilean jack mackerel (T. murphyi) species (70 specimens;
390–420 g weight) were captured in the Pacific Ocean on the coast of
Coquimbo (IV Region, Chile). They were delivered to the laboratory
and individuals were opened within the first 4 h post-mortem headed
and gutted and then, the fish was filleted, cut into pieces (dimensions:
10× 5× 1,5;weight range: 50–55 g),whichwere extracted fromthe dorsal
part of the fish, and placed in flexible high-density polyethylene bags
and vacuum-sealed, and maintained under chilling conditions (~30–
60 min) in a refrigerated room (4 °C) until further HHP processing.
