| Summary: | In this study, the atmospheric cold plasma treatment is carried out at two different powers of 50 and 60 W for two different exposure durations of 30 and 45 min. The treatment had not resulted in a significant difference between the control and plasma-treated samples in values like saponification value, triacylglycerol value, acid value, and free fatty acid value. While there was about a 3% increase in the melting point from 34.1 ± 0.17 °C to 35.23 ± 0.25 °C after 60 W of treatment for 45 min, there was around a 0.9% increase after 50 W of treatment for 30 min. The peroxide value and anisidine value started increasing slowly immediately after cold plasma treatment but still, the values were within the range. There was a significant decrease in the iodine value (56.31 ± 0.26 g of I2/100 g of oil to 51.56 ± 0.01 g of I2/100 g of oil) due to the cold plasma treatment. The TOTOX value which represents the oxidative stability of the palm oil had increased from 12.77 ± 0.93 for the control sample to the maximum value of 16.38 ± 0.28 which was for the 60 W power treatment for 45 min.
