Development of pH ‐Sensitive Intelligent Packaging Films Based on Polyvinyl Alcohol Incorporated With Lycium ruthenicum Anthocyanin and Curcumin for Real‐Time Monitoring of Mutton Freshness
A multifunctional intelligent packaging film was fabricated by co‐incorporating Lycium ruthenicum anthocyanins (LRAs) and curcumin (CUR) into a polyvinyl alcohol (PVA) matrix. Microstructural and spectroscopic analyses supported the successful incorporation of both pigments and their intermolecular interactions w...
