Abstract This work was aimed at assessing the effectiveness of electronic nose to monitor off‐flavor associated with lipid oxidation as a supplementary tool human sensory panel assessment. Therefore, correlations between and analysis were determined. Also GC analyses chemical oil samples run characterize analyzed well‐described parameters. Refined rapeseed subjected an accelerated storage test for 12 days 60 °C ambient temperature in which it stored retail plastic bottles up 6 months. PCA data elevated related analysis, similarities sample clustering observed. For room temperature, showed greater sensitivity than nose. Prediction models based on PLS able predict quality changes during ranging from 0.721 0.989 0.849 0.881 ( p <0.05), respectively. PV p‐AV well predicted basis both (0.989, 0.998 temperature; 0.907, temperature) (0.973, 0.993 0.939, 0.886 temperature). Applicability technology verify rancidity be promising control oils.
