摘要: Abstract The effects of drying method [sun (7 days), oven (72 h at 60 °C) and freeze (∼72 h)] grape (Vitis vinifera L. cv. Pinotage, Shiraz Sauvignon Blanc) variety on pomace fatty acid composition, polyphenolic content antioxidant capacity were evaluated. Furthermore, the influence sun-dried pomaces rumen microbial diversity was assessed in vitro. Freeze-dried had highest proportions 18:1n-9, 18:2n-6, total monounsaturated (MUFA), polyunsaturated acids (PUFA) polyphenolics compared to other drying × variety interactions (P ≤ 0.05). Blanc proanthocyanidin activity for both 2,2-diphenyl-1-picrylhydrazyl (DPPH) ferric reducing power (FRAP) relative Regardless inclusion level, reduced bacterial species abundance, but improved diversity, evenness richness control Overall, freeze-dried best profile content, while activity.
