| FIR Treatment | TP (mg/g GAE dw) | TF (mg/g CUE dw) |
|---|---|---|
| Control | 12.75 ± 0.25 e | 2.51 ± 0.07 c |
| 120 °C | 13.19 ± 0.26 d | 2.60 ± 0.05 c |
| 140 °C | 13.54 ± 0.54 d | 2.73 ± 0.11 c |
| 160 °C | 14.03 ± 0.28 d | 2.76 ± 0.08 c |
| 180 °C | 17.75 ± 0.53 c | 3.94± 0.07 c |
| 200 °C | 20.63 ± 0.41 b | 5.21 ± 0.15 b |
| 220 °C | 22.65 ± 0.22 a | 7.87 ± 0.14 a |
| 240 °C | 17.53 ± 0.35 c | 5.55 ± 0.16 b |
Each value is expressed as the mean ± SD (n = 3). Values labeled with different letters in a column are significantly different (p < 0.05). GAE: gallic acid equivalent; CUE: coumarin equivalent; dw: dry weight.
