Gel strength of raw and agglomerated PPSPs with different concentrations of MD binder over storage time.
| Sample | MD Concentration (%) |
Gel Strength (gf) | ||
|---|---|---|---|---|
| 3 Days | 5 Days | 7 Days | ||
| Raw PPSP | 9.67 ± 0.58 d | 40.7 ± 2.31 d | 108 ± 4.16 d | |
| Agglomerated PPSP | 0 (control) | 21.7 ± 1.53 b | 66.3 ± 1.15 b | 161 ± 1.53 b |
| 10 | 32.3 ± 1.15 a | 76.7 ± 0.58 a | 177 ± 3.79 a | |
| 20 | 21.7 ± 2.08 b | 56.3 ± 1.53 c | 143 ± 2.31 c | |
| 30 | 12.0 ± 1.00 c | 43.0 ± 1.00 d | 111 ± 1.73 d | |
| 40 | 9.00 ± 1.00 e | 26.3 ± 0.58 e | 100 ± 1.00 e | |
Each value is the mean of triplicate measurements ± SD. Means with different lowercase letters (a–e) within each column are significantly different (p < 0.05).
