Preparation of Tea Polyphenol‐Enhanced Whey Protein Isolate/Sodium Carboxymethyl Cellulose Composite Films and Their Antioxidant and Antibacterial Properties
Biodegradable composite films are prepared using whey protein isolate (WPI) and sodium carboxymethyl cellulose (CMC‐Na) as matrices, with tea polyphenols (TP) incorporated into the composite matrix. The incorporation of TP significantly enhances the ultraviolet (UV) barrier performance, antioxidant activity, and an...
