Fabrication and Characterization of a pH-Responsive Intelligent Packaging Film From Amorphophallus paeoniifolius Starch and Clitoria ternatea Extract for Real-Time Chicken Freshness Monitoring.

ABSTRACT: This study aimed to develop a pH-sensitive intelligent packaging film using starch extracted from elephant foot yam (EFY) (Amorphophallus paeoniifolius). The starch was dual-modified and blended with polyvinyl alcohol (PVA) and anthocyanin-rich Clitoria ternatea extract (CTE) to produce composite films capable of real-time chicken meat freshness monitoring. LC-MS/MS profiling confirmed the presence of several phenolic and flavonoid compounds, including rutin, delphinidin, and quercetin. Structural analyses using field-emission scanning electron microscopy (FE-SEM), confocal laser scanning microscopy (CLSM), along with spectroscopic techniques such as Fourier transform infrared spectroscopy (FTIR), x-ray diffraction (XRD), indicated  good dispersion of CTE within a semicrystalline polymer m
