Stability Assessment of KO Emulsion under Accelerated Oxidation Conditions
To assess the stability of the emulsion, lipid oxidation experiments were conducted by placing two sets of emulsions in sealed screw-cap glass tubes covered with aluminum foil. These samples were then incubated for 30 d in an incubator at a temperature of 50 °C to accelerate the oxidation process. At intervals of 5 d, samples were analyzed to monitor the production of primary lipid oxidation products. Measurements were based on the peroxide value (POV) and acid value (AV). The analysis followed the guidelines provided by the American Oil Chemists’ Society (AOCS) official method AOCS Cd 8-53 (AOCS,1998).
