Color Evaluation: Different letters within same columns, same factor and same film applied indicate statistically significant differences. Different superscript letters amongst same factors, regarding the 15th day of storage applied indicate statistically significant differences (p < 0.05).

Firmness Evaluation: Different letters within same column (firmness for each applied film regarding the 7th and 15th day of storage) or at 15th day of storage (all films) indicate statistically significant differences (p < 0.05).
