This study was conducted to evaluate the effectiveness of tea seed oil (TSO) compared with the addition of some antioxidant substancessuch as BHA, BHT, d-α-tocopherol during storagetime(at 60C for 12 days according to the Schaal experiment, 2010) for susceptible oils such as linseed oil (LSO) and walnut oil (WNO). Peroxide (PV) and Para-anisidine (P-av) values were monitored during oxidation of the two oils at 0and 12 days of storage. The Totox value has assessed the formation of LSO first and second oxidation products after 12 days of storage in the control and formula supplemented with 0.02% BHA + BHT, 0.03% tocopherol, 3% TSO, 6% TSO respectively 176.06; 139.3; 154.38; 138.34 and 110.31. In WNO, this value was 204.56 respectively; 173.12; 177.93; 170.46 and 154.29. In this study, TSO was shown to have higher potential than BHA, BHT, tocopherol when blended with 6% TSO. Blending 3% TSO had preservation effect as good as BHA + BHT at the concentrations of 0.0 2% and D-α-tocopherol at 0.03% in inhibiting the oxidation of LSO and WNO.
