Colour value difference between homopolymer blending and monomer blending.a
| Plant‐derived phenols | L* | a* | b* | |
|---|---|---|---|---|
| Homopolymer blending (separated reactions and mixed later) | GA (reacted) + SA (reacted) | 14.4 ± 4.5 | 17.7 ± 5.1 | 9.5 ± 3.0 |
| FA (reacted) + SA (reacted) | 29.3 ± 4.0 | 16.9 ± 2.7 | 18.7 ± 4.3 | |
| CA (reacted) + CAC (reacted) | 14.0 ± 2.5 | 17.8 ± 3.2 | 9.87 ± 2.9 | |
| Monomer blending (mixed already before laccase addition) | GA + SA | 11.2 ± 3.9 | 15.2 ± 4.5 | 7.7 ± 3.8 |
| FA + SA | 12.9 ± 2.7 | 27.0 ± 3.8 | 9.5 ± 1.7 | |
| CA + CAC | 0 ± 0 | 0 ± 0 | 0 ± 0 | |
a.
Homopolymer blending indicates mechanical mixtures of two half volume colouration reactions containing 50% laccase and single monomers. Monomer blending indicates colouration reactions containing laccase and dual monomers. Colour values were measured after 22 h incubation. Means and standard deviations for triplicate samples shown.
