The aims of this study were to determine the descriptive sensory profile and drivers of liking of eight
samples of low-sodium Serra Spanish Mackerel (Scomberomorus brasiliensis) fish burgers. The sensory
profile was determined by 12 trained assessors, and acceptance testing was performed using 243 consumers.
Partial least-squares regression analysis was used to identify the drivers of liking and rejection of
fish burgers (i.e., “Mackerel burger”). The results of the sensory descriptive profile indicated that the
attributes appearance, aroma, and flavor were stronger for the samples prepared from whole minced
fish. Acceptance was also higher for formulations containing whole minced fish. The descriptive terms
that drove consumer preference and determined the acceptance were fish shape, salty taste, umami
taste, fish flavor, herb flavor, and residual artificial flavor, and the term fish shape positively affected the
results. Thus, despite the preparation of a fish-based product with low sodium and high acceptance is
feasible, the drivers of liking should be considered
