Table 3.
Spearman’s correlation coefficients (Spearman’s Rho) between the induction time (IT) and the main variables determined in acid oils (AO) from chemical refining and in fatty acid distillates (FAD) from physical refining.
| Parameter | AO (n = 69) 1 | FAD (n = 13) |
|---|---|---|
| PV | NS | NS |
| p-AnV | NS | –0.577 * |
| POL | –0.375 ** | NA |
| SFA | 0.507 ** | 0.819 ** |
| cis-MUFA | NS | –0.819 ** |
| trans-C18:1 | –0.264 * | NS |
| n-6 PUFA | NS | –0.758 ** |
| n-3 PUFA | NS | –0.830 ** |
| UFA/SFA ratio | –0.507 ** | –0.819 ** |
| T | NS | NS |
| T3 | NS | NS |
| T + T3 | NS | NS |
See Table 2 for abbreviations; NA, not available, because the content of POL was null in FAD. 1 For 10 AO samples, no IT could be determined. NS, not significant coefficient (p > 0.05). * Statistically significant coefficient (p ≤ 0.05). ** Statistically significant coefficient (p ≤ 0.01).
