TOTOX Value
TOTOX values of canola oil samples are shown in Table 3. The obtained results determined green tea extracts whether free or encapsulated in liposome was acted in the form of an effective antioxidant and was while green tea extract liposomes were stronger in the retarding oxidation rate than free extracts. The lowest TOTOX value related to green tea extract liposome at 600 mg/L. Shahidi and Wanasundara reported TOTOX values, in the treated canola oils with canola extract, were lower than control (Shahidi and Wanasundara., 1997).
