| Protein digestibility | 89.82 ± 0.13 a | 77.97 ± 0.5 b | 77.61 ± 0.00 b |
| LGC | 11.50 ± 0.71 a | 11 ± 0.00 a | 10.75 ± 0.35 a |
| Surface hydrophobicity | 5.14 ± 0.11 b | 1.06 ± 0.02 c | 5.80 ± 0.01 a |
| WHC (40 mg/mL) | 0.15 ± 0.05 b | 0.47 ± 0.67 a | 0.10 ± 0.08 b |
| OHC (40 mg/mL) | 1.63 ± 1.97 a | 1.07 ± 1.48 b | 0.92 ± 1.21 b |
Each value is the mean and standard deviation of triplicate determinations. Different superscript characters (a, b, and c) indicate significant differences at p < 0.05 level within a row.
