Functional properties of cellulose nanosphere from different sources compared with commercial cellulose.
| Source of Cellulose Nanosphere | WAI (g/g) | WSI (%) | Swelling Capacity (mL/g) |
|---|---|---|---|
| Rice straw | 7.77 ± 0.15 c | 2.01 ± 0.09 c | 1.91 ± 0.07 c |
| Corncob | 6.82 ± 0.02 cd | 3.64 ± 0.22 b | 2.96 ± 0.03 b |
| Pineapple leaf | 9.30 ± 1.46 b | 9.57 ± 1.06 a | 1.89 ± 0.09 c |
| Pineapple peel | 14.24 ± 0.25 a | 1.57 ± 0.19 c | 9.01 ± 0.10 a |
| Commercial cellulose | 6.18 ± 0.41 d | 1.81 ± 0.20 c | 2.95 ± 0.03 b |
Values are presented as mean ± standard deviation (n = 3). Different superscripts (a–d) in each column are significantly different (p < 0.05). WAI: water absorption index, WSI: water solubility index.
