“…Antibacterial Efficacy against Food Pathogens. The antibacterial effectiveness of PHB-DEA-CafA NPs was determined using the plate counting method at various time intervals (8,12,24, and 48 h) compared to the positive control group. It was apparent that inhibition of bacterial cell viability was dependent on PHB-DEA-CafA NPs concentration.…”

The bioactivities of polyhydroxyalkanoates have been curtailed owing to the lack of bioactive functional groups in their backbones. In this regard, polyhydroxybutyrate (PHB) produced from new locally isolated Bacillus nealsonii ICRI16 was chemically modified for enhancing its functionality, stability as well as solubility. First, PHB was transformed to PHB-diethanolamine (PHB-DEA) by transamination. Subsequently, for the first time, the chain ends of the polymer were substituted by caffeic acid molecules (CafA), generating novel PHB-DEA-CafA. The chemical structure of such a polymer was confirmed by Fourier-transform infrared (FTIR) spectroscopy and proton nuclear magnetic resonance ( 1 H NMR). The modified polyester demonstrated improved thermal behavior compared to PHB-DEA as was shown by thermogravimetric analysis, derivative thermogravimetry, and differential scanning calorimetry analyses. Interestingly, 65% of PHB-DEA-CafA was biodegraded in a clay soil environment after 60 days at 25 °C, while 50% of PHB was degraded within the same period. On another avenue, PHB-DEA-CafA nanoparticles (NPs) were successfully prepared with an impressive mean particle size of 223 ± 0.12 nm and high colloidal stability. The nanoparticulate polyester had powerful antioxidant capacity with an IC 50 of 32.2 mg/mL, which was the result of CafA loading in the polymer chain. More importantly, the NPs had a considerable effect on the bacterial behavior of four food pathogens, inhibiting 98 ± 0.12% of Listeria monocytogenes DSM 19094 after 48 h of exposure. Finally, the raw polish sausage coated with NPs had a significantly lower bacterial count of 2.11 ± 0.21 log cfu/g in comparison to other groups. When all these positive features are recognized, the polyester described herein could be considered as a good candidate for commercial active food coatings.

The biodegradable materials for the packaging sector have attracted much attention as they can effectively reduce the reliance on fossil fuel products. The introduction of two‐dimensional layered fillers is readily available for packaging materials to minimize costs while enhancing performance. However, few studies have investigated the molecular structure changes of OMMT to further modulate the comprehensive performance of polyhydroxy butyrate (PHB) materials. To fill this gap, we innovatively modified the surfactant's structure to regulate the embedding and dispersion of montmorillonite (OMMT) and interfacial bonding with the substrate, thus further examining the material's antibacterial and degrading properties and discussing mechanisms for the first time. The prepared C18M7@PHB materials present enhanced tensile strength (180%) and high thermal stability, excellent antimicrobial properties compared to the unmodified one. Both the water vapor and oxygen permeabilities of composites have decreased by 87% and 55%, respectively. Moreover, it is found that the composites exhibit various degradation cycles mainly depending on active agent chain length. This work lays a solid foundation for multifunctional packaging materials based on fillers with two‐dimensional layered structures.Highlights Determining the ideal film's bulk ratio and active agent structure. Optimizing the film's excellent tensile strength and antimicrobial properties. Significantly blocking the infiltration of water vapor and oxygen. Identifying the film's filler's degradation behavior and barrier mechanism.
