Table 1.
Yield, moisture content, water solubility, viscosity and pH of carboxymethyl chitosan (CMCH) with different MW.
| CMCH | Yield (%) | Moisture Content (%) ns | Water Solubility (%) * | Viscosity (cP) | pH ns |
|---|---|---|---|---|---|
| L-CMCH | 41.33 b ± 0.34 | 6.87 ± 0.12 | 96.87 a ± 0.29 | 325.74 c ± 0.32 | 7.27 ± 0.29 |
| M-CMCH | 43.70 a ± 1.55 | 6.36 ± 0.51 | 90.06 ab ± 3.30 | 336.83 b ± 0.16 | 7.32 ± 0.22 |
| H-CMCH | 45.36 a ± 0.65 | 6.56 ± 0.60 | 89.49 b ± 3.72 | 360.05 a ± 0.84 | 7.33 ± 0.13 |
* Water solubility (%) of L-CMCH, M-CMCH and H-CMCH indicates the comparison to native chitosan. Different letters (a–c) in each column indicate significant differences (p ≤ 0.05). ns means no significant difference.
