The CDs were subsequently incorporated into pineapple stem starch (PSS)-based active food packaging films. The characterization of the CDs and PSS-CDs films was conducted using various techniques, including UV-light spectroscopy, fluorescence spectroscopy, and transmission electron microscopy. The results revealed that the CDs measured 2.36 ± 0.33 nm and exhibited antioxidant and antibacterial activities. The addition of the CDs led to notable enhancements in both mechanical strength and UV-barrier properties. Thus, PSS-CDs packaging film was successfully prepared, with the incorporation of CDs enhancing the antioxidant and antimicrobial properties of the film, thereby extending the shelf-life of fresh pork.Biochemistry, Genetics and Molecular BiologyArticleSCOPUS10.1016/j.ijbiomac.2024.1372242-s2.0-8520828806418790003
