|---|---|---|---|---|
| β-sheets | Random coils | α-Helixes | β-turns | |
| Control | 40.44 ± 1.08d | 14.77 ± 1.36c | 25.67 ± 1.24a | 19.12 ± 1.36c |
| MUE | 46.49 ± 0.78a | 20.95 ± 1.25a | 17.03 ± 1.36b | 15.52 ± 2.15d |
| CE | 41.13 ± 0.63c | 16.27 ± 0.87b | 16.16 ± 2.15c | 26.44 ± 1.63a |
| MUCE | 44.93 ± 1.24b | 16.12 ± 0.69b | 15.11 ± 1.09d | 23.77 ± 0.96b |
Values were mean ± standard deviation. The different superscript letters within the same column mean significant differences (p < 0.05). (Control: traditional extraction; MUE: multi-frequency ultrasound extraction; CE: cellulase extraction; MUCE: multi-frequency ultrasound-assisted cellulase extraction).
