Honey is a product traditionally consumed due to its possible health benefits promoted by natural antioxidants. However, few studies have evaluated the effect of in vitro gastrointestinal digestion on these compounds in honeys. To improve the knowledge of this subject, the present study aimed to investigate the influence of simulated digestion on the stability of antioxidant capacity (FRAP, DPPH, and Folin-Ciocalteu assays), phenolic compounds (LC-ESI-MS/MS), and minerals (CE-DAD) in Mimosa scabrella Bentham honeydew honeys. The results show that the digestive system, mainly after duodenal digestion, significantly decreased the antioxidant capacity assessed by FRAP (410.3±18.3 to 564.7±8.4μmolFe100g), DPPH (30.1±0.8 to 33.9±1.4mgAAE100g), and Folin-Ciocalteu assays (58.3±2.6 to 142.0±1.6mgGAE100g) of this honey. However, phenolic compounds and minerals showed high stability and in some cases, significantly increased after the simulated digestion, presenting a bioaccessible fraction that ranged from 78.2±6.4 to 174.38±6.82% and 94.0±4.3 to 220.5±3.4%, respectively. Therefore, these honey constituents may be considered highly bioaccessible and potentially bioavailable. Additionally, the correlation between the investigated parameters suggests that other honey constituents could also possibly affect antioxidant capacity of this honey. In conclusion, the bracatinga (Mimosa scabrella Benth.) honeydew honey can be highlighted as an important natural source of bioaccessible polyphenols, besides presenting highly bioaccessible minerals in its composition, maintaining a satisfactory antioxidant capacity.
蜂蜜是一种传统上被消费的产品，因为其天然抗氧化剂所带来的潜在健康益处。然而，很少有研究评估体外胃肠道消化对蜂蜜中这些化合物的影响。为了提高对这一主题的认识，本研究旨在研究模拟消化对抗氧化能力（FRAP、DPPH 和 Folin-Ciocalteu 测定法）、酚类化合物（LC-ESI-MS/MS）和矿物质（CE-DAD）稳定性的影响在 Mimosa scabrella Bentham 蜜露蜂蜜中。结果表明，消化系统，主要是十二指肠消化后，显著降低了 FRAP（410.3±18.3 至 564.7±8.4μmolFe100g）、DPPH（30.1±0.8 至 33.9±1.4mgAAE100g）和 Folin-Ciocalteu 测定法（58.3±2.6 至 142.0±1.6mgGAE100g）评估的这种蜂蜜的抗氧化能力。然而，酚类化合物和矿物质表现出很高的稳定性，在某些情况下，模拟消化后会显著增加，呈现出 78.2±6.4 至 174.38±6.82%和 94.0±4.3 至 220.5±3.4%的生物可利用分数。因此，这些蜂蜜成分可被认为是高度生物可利用的，并且可能具有生物可利用性。此外，研究参数之间的相关性表明，其他蜂蜜成分也可能影响这种蜂蜜的抗氧化能力。总之，bracatinga（Mimosa scabrella Benth.）蜜露蜂蜜可以作为生物可利用多酚的重要天然来源得到强调，此外，其成分中还含有高度生物可利用的矿物质，保持了令人满意的抗氧化能力。
