Effect of ozone treatment on peroxide values. Values are presented as mean ± standard deviation (n = 2). CTR—control.
| Sample | Ozonation time | Peroxide Value 1 |
|---|---|---|
| CTR | 0 | 3.9 ± 0.0 a |
| 1 | 10 min | 44.4 ± 3.4 b |
| 2 | 20 min | 69.5 ± 4.6 c |
| 3 | 40 min | 83.4 ± 5.3 c |
| 4 | 80 min | 101.7 ± 4.7 d |
| 5 | 160 min | 113.5 ± 3.7 d |
| 6 | 320 min | 220.7 ± 5.6 e |
1 Peroxide value was expressed as milli-equivalents (meq) peroxide per 1 kg oil. Analysis of variance (ANOVA) was performed, with different letters (a–e) indicating significant differences (p < 0.05).
