Agro-industries residues of fruit are a source of antioxidant compounds with a possible health impact. The aim of this study was to evaluate the total phenolic content (TPC), total monomeric anthocyanins (TMA), individual phenolic compounds (IPC), antioxidant capacity and in vitro intestinal bioaccessibility from blackberry residues (BR), and ultrasonicated blackberry residues (US-BR). The results showed that BR had higher TPC (4,016.43 mg GAE/100 g DM), TMA (364.53 mg Cy-3-Gl/100 g) antioxidant capacity by ABTS (5,422.38 mg AAE/100 g DM) and FRAP (12511.44 μmol Fe(II)/100 g DM) than US-BR. TPC and TMA obtained by US-BR were more bioaccessible (70 and 51%, respectively) compared to BR (37 and 34%, respectively). The use of ultrasound can aid the extraction of total phenolic compounds and improve their bioaccessibility. After acid hydrolysis, a high amount of individual phenolic compounds (IPC) in US-BR (chlorogenic acid, caffeic acid, apigenin, luteolin and kaempferol) was obtained compared with BR. Before in vitro digestion, total individual compounds (TIC) content was lower in the BR (29.49 mg/100 g DM) than US-BR (92.36 mg/100 g DM) and there was 5 and < 1%, respectively. Therefore, the food industry would use residues of blackberry fruits as a source of antioxidant compounds with possible health benefits.

超声波对酚类化合物的体外生物可及性和黑莓 (Rubus fruticosus) 残留物抗氧化能力的影响 cv。图比

水果的农业工业残留物是抗氧化化合物的来源，可能对健康产生影响。本研究的目的是评估黑莓残留物 (BR) 和超声波处理黑莓残留物 (美国) 的总酚含量 (TPC)、总单体花青素 (TMA)、单个酚类化合物 (IPC)、抗氧化能力和体外肠道生物可及性。 -BR)。结果表明，BR 具有更高的 TPC (4,016.43 mg GAE/100 g DM)、TMA (364.53 mg Cy-3-Gl/100 g) ABTS (5,422.38 mg AAE/100 g DM) 和 FRAP (12511.44 μmol Fe) 的抗氧化能力(II)/100 g DM) 比 US-BR。与 BR（分别为 37% 和 34%）相比，通过 US-BR 获得的 TPC 和 TMA 的生物可及性更高（分别为 70% 和 51%）。超声波的使用有助于提取总酚类化合物并提高其生物可及性。酸水解后，与 BR 相比，在 US-BR（绿原酸、咖啡酸、芹菜素、木犀草素和山奈酚）中获得了大量的单独酚类化合物 (IPC)。在体外消化之前，BR (29.49 mg/100 g DM) 中的总单个化合物 (TIC) 含量低于 US-BR (92.36 mg/100 g DM)，分别为 5% 和 < 1%。因此，食品工业将使用黑莓果实的残留物作为可能对健康有益的抗氧化化合物的来源。
