Grape pomace (GP) from juice production is a source of bioactive compounds with antioxidant properties. This work aimed to study the antioxidant capacity in extracts produced from GP using a Central Composite Rotatable Design (CCRD) for evaluation of the effects of the temperature and pH during enzymatic hydrolysis with pectinase and cellulase. The best conditions for enzyme maceration and obtaining extracts with improved antioxidant properties were: application of pectinase (0.70%) plus cellulase (0.30%), 55 °C as incubation temperature and pH 4.5. At these conditions, the produced GPs extracts exhibited strong antioxidant capacity in ABTS, DPPH and FRAP methods, representing a source of bioactive compounds.
