Antioxidant Action of Phytic Acid in Processed Fish Waste and Cooked Fish Sausages

ABSTRACTThe study evaluated the efficiency of phytic acid (PA) for stabilization of processed fish waste (PFW – ventral muscle and vertebral column without fins) and its use as a substitute for pork in cooked sausages. The PA and sodium erythorbate (0.05%) was compared by quantifying hydroperoxides. PFW stabilized with 0.05% PA was used to replace pork (0, 25, 50, and 75% PFW) sausage formulation. All formulations showed a difference in texture in comparison to control, which had higher levels of hydroperoxides. Phytic acid has antioxidant action on PFW, optimized in 0.05%. PFW can substitute up to 25% for pork in cooked sausages.KEYWORDS: Aquaculturefish productmechanically separated meatoxidative stability AcknowledgmentsThe authors are thankful to the financial assistance provided by the Foundation Coordination for the Improvement of Higher Education Personnel (CAPES) by means of a Master's degree scholarship, and to the National Council for Scientific and Technological Development (CNPq) for granting a research productivity scholarship to Professor Leila Picolli da Silva.
