Polyphenols from halophytes and modified atmosphere packaging improve sensorial and biochemical markers of quality of common dolphinfish (Coryphaena hippurus) fillets.
Quality and shelf-life of whole and filleted Coryphaena hippurus, stored with modified atmosphere packaging (MAP) and natural antioxidants from halophytes (HAL), were investigated. Fillets were divided into control, simply sealed in trays; MAP, preserved by modified atmosphere (45% CO2, 50% N2, 5% O2); and MAP-HAL, pretreated with antioxidants and preserved by MAP. Whole and filleted fish were stored at -1 ± 0.5°C for 18 days. The quality of the samples was analyzed at the time of packaging and after 3, 6, 9, 12, 15, and 18 days. The MAP and MAP-HAL groups maintained the best sensorial profile, pH, and drip loss with respect to the untreated fillets. Higher levels of total volatile basic nitrogen (TVB-N) and oxidized proteins were observed in untreated samples with respect to the MAP and MAP-HAL groups. The principle component analysis revealed a different quality profile for untreated and MAP-treated fish.
