Table 5.
Values of the activation energy (Ea) and preexponential factor (η∞), obtained from the flow curve data regression by the Arrhenius model at a fixed shear rate (50 s−1) and variable temperature (T = 10–60°C), for experimental (SA) and commercial spreads (SB and SC) of Table S1.
| E a (kJ/mol) | η ∞ · 106 (Pa·s) | R 2 | |
|---|---|---|---|
| S A | 30.20 ± 0.55a | 26.71 ± 5.29b | 0.979 |
| S B | 42.11 ± 0.21c | 0.36 ± 0.04a | 0.962 |
| S C | 31.46 ± 0.04b | 23.72 ± 0.17b | 0.972 |
Values are reported as mean values ± s.d. For each parameter, different lowercase letters indicate significantly different means (p < 0.05).
