Bioaccessibility of phenolic compounds of jaboticaba (Plinia jaboticaba) peel and seed after simulated gastrointestinal digestion and gut microbiota fermentation

•First study on the gut fermentation of jaboticaba phenolic compounds.•After gastric digestion phenolic compounds bioaccessibility was 47%.•Intestinal pH decreased anthocyanins and increased ellagic acid bioaccessibility.•Nutrient-rich fermentation medium showed the highest phenolics bioaccessibility.•Metabolization by gut microbiota decreased phenolics bioaccessibility to 19%.
