Web1 okt. 2024 · Determining the peroxide value (PV) of edible oils is essential because PV is one of the most typically used quality parameters to monitor lipid oxidation and control oil quality. Many approaches have been developed to determine the PV of oils. Among them, iodometric titration is the commonly used method for PV determination. WebIodometric Titration Principle H2O2 oxidizes iodide to iodine in the presence of acid and molybdate catalyst. The iodine formed is titrated with thiosulfate solution, incorporating a starch indicator. H2O2 + 2 KI + H2SO4 → I2 + K2SO4 + 2 H2O I2 + 2 Na2S2O3 → Na2S4O6 + 2 NaI Scope of Application
