*2.6. Statistical Analysis*

The results were expressed as mean ± standard deviation (SD). The data were analyzed using the statistical program IBM SPSS Statistics 25 (https://www.ibm.com/analytics/spss-statistics-software). The significant difference among means was analyzed by Student's T-test (assuming the normal distribution of the continuous variables). A level of *p*-value < 0.05 was considered significant. Linear regression was also performed for antioxidant activity of the films measured by DPPH scavenging assay considering the % Inhibition as a function of time.
