Özet

Biopolymer-based nanocomposites are a new type of material that exhibits significantly improved properties, such as barrier, mechanical, and thermal characteristics. They are considered non-toxic and alternative food packaging materials. Therefore, the production of biopolymer-based active films has been initiated to reduce the environmental problems caused by non-biodegradable plastic waste and eliminate their negative effects on human health. In this study active food packaging films based on poly(vinyl alcohol)/boric acid/montmorillonite (PVA/BA/MMT) nanocomposite incorporated with ferulic acid (FA) were synthesized using solution casting method. The structural, thermal, transmittance, antimicrobial, and antifungal properties of nanocomposite films have been investigated. The fourier transforms infrared (FTIR) spectroscopy used to demonstrate the chemical structure of films and interaction between boric acid (BA) and PVA. X-Ray diffraction analysis (XRD) was performed to determine the dispersion and exfoliated of the montmorillonite in the PVA matrix. Thermal stability of PVA/BA/MMT films incorporated with FA were evaluated by using TG/DTA analyzer. Optical properties of films and PVA determined using by UV/VIS spectrophotometer in the range of 400-700 nm wavelength at scanning percent transmittance. The transmittance of PVA exhibited UV light 89.2% of T700 and 86.7% of T400, indicating the high transparency of PVA. The antimicrobial activity of PVA membranes samples was carried out test method AATCC 100. According to the antimicrobial activity test, more than 300 colonies were detected for all microorganisms in the samples belonging to the PVA group. But the antimicrobial and antifungal activity of the films incorporated with FA could inhibit bacterial growth. It has been determined that the nanocomposite films have antibacterial properties against Escherichia coli (E.coli, ATCC 25922), Staphylococcus aereus (S. aereus, ATCC6538), and antifungal properties against Candida albicans. © 2023, Turkish Chemical Society.
