---|---|---|---|---|
species | C | O | ratio (C:O) | modify % (DS) |
CNF | 47.7 | 52.3 | 0.91 | 0 (0) |
CNFa | 49.7 | 50.3 | 0.99 | 29.4 (0.88)a |
CNFp (1 h) | 51.2 | 48.8 | 1.05 | 20.8 (0.62) |
CNFp (2 h) | 52.5 | 47.5 | 1.11 | 30.7 (0.92) |
CNFp (4 h) | 55.0 | 45.0 | 1.22 | 51.8 (1.55) |
DS of CNFa is calculated using different equations due to its different molecular weights.
