Chicken meat is one of the foods in which microorganisms grow rapidly and so has a short shelf life. Extending the shelf life of food is also important for the economy. Packaging with biodegradable antimicrobial materials can reduce the rate of microorganism growth. In material studies on antimicrobial essential oils, carvacrol is generally used, and it is one of the most effective antimicrobial compounds of the Origanum onites species. Polylactic acid (PLA) is a biodegradable, natural polymer and a food-compatible biopolymer that is economical to produce. In this study, PLA nanofibers loaded with carvacrol (PLA/C) at 10, 20, and 30% (v/w) were produced by the solution blow-spinning method (SBS), and their antibacterial effects against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) were measured by the disk diffusion method. Chicken breast meat samples packaged with PLA/C nanofibers were stored at +4 °C for 7 days, and the increase in total aero-mesophilic bacteria values was determined as 5 × 105, 5 × 104, 5 × 103, and 4 × 103 cfu/g for PLA/C, respectively. All processes were analyzed in triplicate, and the consistency of the results was tested at 5%. PLA/C nanofiber was characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy, and thermogravimetric analysis (TGA). Nanofiber diameters in SEM images were between 1.01 and 3.21 μm. According to TGA data, the nanofiber showed degradation at 378.21 °C.PMID:41696245 | PMC:PMC12902995 | DOI:10.1021/acsomega.5c02604
