Effect of high-intensity ultrasound treatment (20 kHz at 400 W for 0, 5, 20, 40 min) on the average particle size (Z-average) and polydispersity index of CSPI and DGH.
| Sample | CSPI | DGH | ||
|---|---|---|---|---|
| Z-Average (nm) | PDI | Z-Average (nm) | PDI | |
| 0 min | 66.09 ± 4.93 a | 0.428 ± 0.040 b | 48.90 ± 0.45 a | 0.897 ± 0.108 b |
| 5 min | 90.52 ± 1.13 c | 0.341 ± 0.033 a | 119.57 ± 1.36 c | 0.321 ± 0.038 a |
| 20 min | 72.10 ± 0.03 b | 0.382 ± 0.012 ab | 131.90 ± 1.64 d | 0.308 ± 0.010 a |
| 40 min | 67.42 ± 0.19 ab | 0.374 ± 0.012 a | 75.29 ± 1.59 b | 0.412 ± 0.028 a |
Values are means ± standard deviation. Different lowercase letters (a, b, c, d) indicate significant differences (p < 0.05, Duncan′s test) between high-intensity ultrasound HIU times in the same column.
