Overview

Research demonstrates the antioxidant potential of microencapsulated polyphenols in Caco-2 cells, suggesting new uses for grape pomace.

Key Points

  • The microencapsulated extract significantly reduced intracellular ROS levels by 65% at a concentration of 250 µg/mL.
  • Eighty percent ethanol extract exhibited the highest antioxidant capacity with a FRAP value of 2909.3 ± 37.6.
  • The method utilized was a cost-effective microencapsulation technique to preserve sensitive bioactive compounds from grape pomace.
  • This study supports the sustainable valorization of Carménère grape pomace, emphasizing its functionality in health applications.
