Validation study of Free Fatty Acids and Peroxide Value determination made by Universities in Republic of Korea
The reliability and availability of CDR FoodLab® system for determining acid value (AV) and peroxide value (POV) were assessed
during the hydrolytic rancidification and lipid oxidation of edible oils.
The CDR FoodLab® system based on spectrophotometry was compared to the official methods, ISO 660 (AOCS Cd 3d-63 or AOCS Ca 5a-40 or AOAC 940.28 ) and ISO 3960 ( AOCS Cd 8b-90 or AOAC 965.33) protocols, based on manual titration employing the standard mixture for the simulated
oxidation models and edible oils during the thermally induced oxidation at 180°C.
Considering ISO protocols with a probability of human error in manual titration, the rapidness and simplicity of the reagent kit based on spectrophotometry make it a very good alternative to monitor the lipid
oxidation of edible oils and lipid-containing foods.
