However, its inherent brittleness has limited its application in food packaging films. To overcome this limitation, acetylated monoglyceride (AMG), a food additive containing both a non\u2010polar hydrocarbon chain and the polar carbonyl group of an ester, was evaluated as a plasticizer to enhance ductility. Among AMGs with various aliphatic chain lengths (C2:0 to C18:1), the cis\u2010configured C18:1 AMG (diacetylated monoolein) exhibited superior mechanical performance compared to other AMGs, indicating a significant enhancement in the flexibility of plasticized PLA films. FT\u2010IR and SEM analyses confirmed the homogeneous distribution and non\u2010covalent interactions between C18:1AMG and PLA, maintaining the polymer's structural integrity. Thermal analyses revealed decreased glass transition and melting temperatures, suggesting increased chain mobility without compromising thermal stability. In addition, UV and visible light transmittance of PLA\u2010C18:1AMG films effectively reduced enzymatic browning in fresh\u2010cut potatoes, highlighting their potential for food packaging applications. Although the mechanical properties of PLA films plasticized with C18:1AMG do not fully reach those of conventional petroleum\u2010based plastics, chemical modification of C18:1AMG or its formulation in blends with other plasticizers is expected to significantly enhance the mechanical properties of PLA.<\/jats:p>\n
