“…The crystallinity of nanocomposite films was analyzed by X‐ray diffraction (XRD) (Figure 4a,b). The incorporation of AgNP‐SL could be confirmed by the diffraction peaks at 38° and 44°, corresponding to the occurrence of crystalline silver nanoparticles 42,47 . These results were more easily detected in the formulations with higher AgNP‐SL concentrations (ST + 1% and ST + 4%), which suggests that lower concentrations were more dispersed in the film matrix and, therefore, hardly detected.…”

“…The darkening of the films would help preventing the UV light penetration, which may contribute to nutritional and quality attributes of food products 41 . As pointed out by Samira et al, 42 transparency is not always a desirable feature for food packaging. Dairy, meat, and food products with high fatty content may be benefited by dark films, as it would help preventing oxidation process induced by light.…”

This study aimed to synthesize silver nanoparticles with sophorolipids (AgNP‐SL) and develop starch nanocomposite films with improved properties to be explored in food packaging applications. AgNP‐SL were spherical and highly stable, with an average size of 61.46 nm. They also demonstrated potent antibacterial action against Escherichia coli and Staphylococcus aureus, revealing its promising application for antimicrobial packaging. The addition of AgNP‐SL into films resulted in color changes, which could contribute to a better UV‐barrier capacity. Nanoparticles and tartaric acid incorporation resulted in a heterogeneous matrix, suggesting chemical interactions between the compounds and the biopolymer. The nanocomposite films presented thermal stability, enhanced flexibility, and antimicrobial action against E. coli, Salmonella enterica serovar Enteritidis, and S. aureus. The combination of AgNP‐SL and tartaric acid resulted in pronounced bactericidal properties. The results demonstrate the great potential of these nanocomposite films as an effective packaging material against foodborne pathogens.
