The aim of this study was to produce a new bioactive composite film using whey protein concentrate and jujube mucilage reinforced with postbiotics of Bacillus coagulans IBRC-M 10807. For this purpose, four films including whey protein concentrate film (WPC), whey protein concentrate film containing B. coagulans postbiotics (WPC+PBs), whey protein concentrate film and jujube mucilage (WPC+MUC), and whey protein concentrate film and jujube mucilage containing B. coagulans postbiotics (WPC+PBs+MUC) each in three replicates of production and their physicochemical, antimicrobial, antioxidant and mechanical, were compared in the form of a completely random design and with the analysis of variance method. The results showed that the addition of postbiotics and jujube mucilage caused a significant increase in the moisture and solubility of the films (P<0.05). Adding postbiotics causes an inhibitory effect against Staphylococcus aureus and Escherichia coli bacteria (P<0.05). The addition of postbiotics and jujube mucilage caused a significant decrease in the L index of the produced film samples (P<0.05). The results showed that the a and b indexes increased significantly with the addition of postbiotics and jujube mucilage (P<0.05). The results of the present study showed that the produced bioactive biocomposite film has the potential to be used in food packaging.
