FW, film with water extract; FWM 70/30, film with water–methanol (70/30, v/v) extract; FWM 50/50, film with water–methanol (50/50, v/v) extract; FWE, film with water–enzyme extract; control, without phytic acid and chicory root extract; 0%, with phytic acid and without chicory root extract. Same superscript letter indicates no statistically significant differences of a given parameter; lowercase letters indicate statistical significance among different concentrations of the same extract, and capital letters indicate the same concentration of different extracts (p < 0.05).
