Developing Metal–Polyphenol Network‐Based Single‐Protein Particle Encapsulation System for Sustained Release of Whey Protein to Mitigate Sarcopenia

Advanced Science, EarlyView.
Sarcopenia has emerged as a major health challenge in the aging population. Developing a sustained‐release system for whey protein may enhance its effectiveness in mitigating sarcopenia. Herein, a novel “single‐protein particle encapsulation” (SPPE) system is developed to protect whey protein and control its release.
