Transylvanian Grape Pomaces as Sustainable Sources of Antioxidant Phenolics and Fatty Acids-A Study of White and Red Cultivars.

ABSTRACT: Grape pomace (GP), a significant by-product of winemaking, is gaining increasing recognition for its potential as a source of bioactive compounds with antioxidant and cardioprotective properties. This study aimed to characterize the polyphenolic profile, fatty acid composition, and antioxidant activity of 17 GP samples from Transylvanian cultivars. Polyphenolic content was determined using the Folin-Ciocalteu method and high-performance liquid chromatography coupled with diode array detection and electrospray ionization mass spectrometry (HPLC-DAD-ESI MS) analysis. Fatty acid composition was analyzed using gas chromatography with flame ionization detection (GC-FID). Antioxidant capacity was assessed using five methods, which included the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scaveng
