a The code sample of composite films includes the following: “CG” from composite gel; “F” or “M” from the variety of the grape pomace extract, Feteasca Neagra or Merlot. The final number from the sample codes represents the amount of extract entrapped within the composite matrices. All samples were prepared upon seven freeze-thawing cycles. b SR represents the swelling ratio and was evaluated by Equation (1) (see Section 4, Materials and Methods).
