RT Journal Article T1 Açaí extract powder as natural antioxidant on pork patties during the refrigerated storage A1 Bellucci, Elisa Rafaela Bonadio A1 dos Santos, João Marcos A1 Carvalho, Larissa Tátero A1 Borgonovi, Taís Fernanda A1 Lorenzo Rodríguez, José Manuel A1 Silva Barretto, Andrea Carla da K1 3309.21 Alimentos Proteínicos K1 3309.03 Antioxidantes en Los Alimentos K1 3309.22 Refrigeración AB The current trends among consumers are pushing for the use of natural antioxidants options. Açaí fruit is rich onpolyphenolic components but no studies have been carried out to evaluate their effect in meat products. Theobjective was to investigate the effect of açaí extract on refrigerated pork patties quality. Five treatments weredone: without antioxidant (CON), Sodium Erythorbate 500 mg.kg − 1 (ERY), Açaí Extract: 250 (AEL), 500 (AEM),750 mg.kg − 1 (AEH). Açaí extract did not affect the proximate composition, pH and cooking parameters. Theconcentrations of açaí extract studied increased antioxidant activity and reduced lipid oxidation (0.379, 0.293,and 0.217 vs. 0.889 mg MDA.kg− 1 for AEL, AEM, AEH vs. CON, respectively). However, only the AEL treatmentdid not affect the color parameters, showing the best option for the application on pork patties. Thus, açaí extractat 250 mg.kg− 1 can be used as a natural antioxidant replacing sodium erythorbate to preserve the quality ofrefrigerated pork patties PB Meat Science SN 03091740 YR 2022 FD 2022-02 LK http://hdl.handle.net/11093/4646 UL http://hdl.handle.net/11093/4646 LA eng NO Meat Science, 184, 108667 (2022) NO CYTED | Ref. 119RT0568 DS Investigo RD 28-abr-2025
