dc.description.abstractFISH AND FISH PRODUCTS ARE CHARACTERIZED FOR HAVING A SHORT SHELF LIFE. NONTHERMAL PROCESSING TECHNIQUES SUCH AS HIGH HYDROSTATIC PRESSURE (HHP) HAVE INCREASINGLY BEEN EMPLOYED TO EXTEND SHELF LIFE OF FOOD PRODUCTS. THE AIM OF THIS STUDY WAS TO EVALUATE CHANGES ON FLESH PHYSICOCHEMICAL SPOILAGE PARAMETERS (PH, TOTAL VOLATILE BASES (TVB-N), TRIMETHYLAMINE (TMA), THIOBARBITURIC ACID (TBA), AND COLOR) OF PALM RUFF (SERIOLELLA VIOLACEA) FILLETS IN PRE- AND POST-RIGOR CONDITIONS, SUBJECTED TO TWO DIFFERENT HHP CONDITIONS: 450 MPA AND 550 MPA, FOR 3 AND 4 MIN EACH. UNPRESSURIZED AND PRESSURIZED FILLETS WERE KEPT IN CHILLED STORAGE (4 ± 1°C) FOR 26 DAYS TO ASSESS THE EFFECT OF HHP ON SHELF LIFE. PH AND TBA VALUES INCREASED AFTER HHP TREATMENT AND WITH STORAGE TIME FOR BOTH UNPRESSURIZED AND PRESSURIZED SAMPLES. THIS IS ATTRIBUTABLE TO PRESSURE-INDUCED LIPID OXIDATION. LIGHTNESS (L*) VALUES INCREASED WITH PRESSURE, WHERE FISH FILLETS HAD A COOKED APPEARANCE. TMA AND TVB-N VALUES DECREASED AFTER HHP TREATMENT COMPARED TO THE UNPRESSURIZED SAMPLES, SHOWING THAT HHP TREATMENT IS AN EFFICIENT METHOD TO MAINTAIN THE QUALITY OF PALM RUFF FILLETS. THERE WAS NO CLEAR DIFFERENCE BETWEEN PRE- AND POST-RIGOR IN THE PARAMETERS EVALUATED.
