Overview

Randomized trial applies subcritical water extraction to improve antioxidant capacity in grape pomace, indicating its potential as a functional ingredient.

Key Points

  • This research investigates the efficiency of subcritical water extraction for valorizing grape pomace into functional ingredients.
  • Applied subcritical water extraction at 120, 140, and 160 °C on grape pomace (GP)
  • Evaluated soluble fraction yield, phenolic content, and antioxidant capacity of extracts
  • Encapsulated extracts in maltodextrin or pectin for stability improvement
  • E-120 extraction yielded 61 g soluble fraction/100 g GP with 4.1 g GAE/100 g extract solids and EC50 of 0.79 mg extract/mg DPPH.
  • Insoluble residue retained 10 g GAE/100 g with EC50 of 1.5 mg residue/mg DPPH and high fiber composition.
  • Encapsulated extracts formed a stable glassy powder with Tg ~50 °C and thermal stability up to 200 °C.
