Table 1 Advantages and disadvantages of the enzymatic and sulfuric acid methods for CNF quantification
Enzymatic method | Phenol–sulfuric acid method | |
|---|---|---|
Lower limit of measurable concentration | ~ 1 mg/L | ~ 10 mg/L |
Time required for measurement | ~ 24 h | ~ 2 h |
Required reagents | Cellulase, glucose assay kit (somewhat costly) | Phenol, sulfuric acid (deleterious substances) |
Interference by algae | Low | High |
Interference by non-cellulosic polysaccharides | Low | High |
