Which trio of metrics are researchers employing to assess the quality and oxidation status of extracted Nile perch oils?

Answer

Peroxide Value (PV), Anisidine Value (AV), and Total Oxidation (TOTOX)

Assessing the quality and safety of fish oils, especially those extracted from by-products like the fat pads of Nile perch, relies on standardized chemical measurements to detect oxidation, which leads to rancidity. Researchers specifically evaluate these oils using three key metrics: the Peroxide Value (PV), which measures the initial stages of primary oxidation products; the Anisidine Value (AV), which quantifies secondary oxidation products such as aldehydes; and the Total Oxidation (TOTOX) value, which is derived from both PV and AV to give a comprehensive measure of overall oxidative history. The text indicates that successful extraction processes result in low PV and AV values (with AV being below the standard of 20 meq/kg), demonstrating that the omega-3 rich oils maintain high stability and are suitable for human consumption.
