As Prussian carp (Carassius gibelio) is one of the most consumed local fish in Romania, the present study is focused on challenge testing of Nigella sativa fortified Carassius gibelio whole fish muscle sample morphological quality. The challenge testing involved exposure to atypical temperature conditions, other than those anticipated in the food industry, including stress temperature trial (exposure to storage temperature variations) for fresh Carassius gibelio whole fish, supplemented with 0.6% v/w Nigella sativa seed oil (NSSO). Histological evaluation of muscle structure was performed at day 3 of storage, for all samples. Histological assessment of dorsal skeletal fish muscle revealed no significant differences between the NSSO enriched challenged sample groups and the control group, after three days of storage. This study shows promising results for the possible use of Nigella sativa seed oil, as a natural solution for extending shelf life and enhancing the quality of cold-stored fresh Prussian carp.
