Opacity and UV–visible transmission of active films containing different levels of VOE.
| Films | Opacity (mm−1) | T280 (%) | T600 (%) |
|---|---|---|---|
| VOE0% | 0.347 ± 0.006 d | 44.61 ± 0.47 a | 75.24 ± 0.72 a |
| VOE1% | 0.491 ± 0.013 c | 7.39 ± 0.31 b | 34.19 ± 0.65 b |
| VOE2% | 0.758 ± 0.019 b | 0.00 ± 0.00 c | 29.93 ± 0.89 c |
| VOE3% | 1.014 ± 0.010 a | 0.00 ± 0.00 c | 17.87 ± 0.82 d |
Values represent the mean (n = 3) ± SD. Different letters in each column represent significant differences among samples at a 5% probability level. VOE: Violata orodata extract.
