Intelligent packaging with a pH indicator is a protective measure that can assure the food quality at the point of delivery or usage. This research targets to develop eggshell membrane gelatin-based hydroxyapatite (HAP) nanocomposite edible film incorporated with anthocyanin extracted from Jambolão (). The HAP nanoparticles were synthesized from eggshells, the size (< 100 nm) and morphology were confirmed by Dynamic light scattering (DLS), Scanning Electron Microscope (SEM), and Transmission Electron Microscope (TEM). Eggshell gelatin film, eggshell gelatin film reinforced with HAP (Gel-HAP), and anthocyanin incorporated eggshell gelatin film reinforced with HAP (Gel-HAP-ACN) were prepared. The physicochemical, optical, and surface properties of the nanocomposite films were evaluated. Gel-HAP-ACN film had excellent light barrier characteristics than Gel-HAP and Gel films. The Gel-HAP-ACN film had enhanced antioxidant (57.71%) property than the gelatin film and also had antibacterial action against , and . Hence, this report suggests Gel-HAP-ACN film for food packaging to assure the safety of the food.

带有pH指示剂的智能包装是一种保护措施，可在交付或使用时确保食品质量。本研究旨在开发一种基于蛋壳膜明胶的羟基磷灰石（HAP）纳米复合可食用薄膜，其中掺入了从Jambolão中提取的花青素。HAP纳米颗粒由蛋壳合成，其尺寸（<100nm）和形态通过动态光散射（DLS）、扫描电子显微镜（SEM）和透射电子显微镜（TEM）得以确认。制备了蛋壳明胶薄膜、用HAP增强的蛋壳明胶薄膜（Gel-HAP）以及用HAP增强并掺入花青素的蛋壳明胶薄膜（Gel-HAP-ACN）。对纳米复合薄膜的物理化学、光学和表面性质进行了评估。Gel-HAP-ACN薄膜比Gel-HAP和Gel薄膜具有优异的阻光特性。Gel-HAP-ACN薄膜比明胶薄膜具有增强的抗氧化性能（57.71%），并且对[具体细菌名称]、[具体细菌名称]和[具体细菌名称]具有抗菌作用。因此，本报告建议使用Gel-HAP-ACN薄膜进行食品包装，以确保食品的安全性。
