What to know about A pectin and chitosan film to protect bioactive compounds in foods and therapies

Researchers from IMDEA Materials and ICTP-CSIC have developed a biodegradable multilayer film using pectin and chitosan to protect anthocyanins from degradation in the stomach. This system allows for the controlled release of these antioxidants in the intestines, potentially improving the efficacy of functional foods and supplements.
