The present work focuses on the evaluation of AFB1's bioaccessibility and cytotoxicity using bread (naturally contaminated) enriched or not enriched with fresh Voghiera garlic (2%). Two different experiments were carried out: experiment 1 (E1), with low-AFB1-concentration breads (1.6-1.7 mg/kg); and experiment 2 (E2), with high-AFB1-concentration breads (96.4-102.7 mg/kg). Eight breads were prepared, four for E1 (experiment 1) and another four for E2 (experiment 2), with each experiment having a control group (C), a garlic-enriched group (2%) (G), an AFB1 group (A), and an AFB1 + garlic group (A + G). Simulated digestion was performed on each type of bread, and gastric and intestinal digests were obtained. AFB1 content in flours, baked bread, and gastric and intestinal digests was measured by High-Performance Liquid Chromatography coupled to Fluorescence Detection. The results demonstrate dose-dependent AFB1 bioaccessibility and that the presence of garlic contributed to its reduction in both doses (7-8%). Moreover, garlic's presence in AFB1-contaminated bread increased cell viability (9-18%) in differentiated Caco-2 cells and mitigated the arrest of S and G2/M phases provoked by AFB1 on Jurkat T cells and reduced apoptosis/necrosis, cellular reactive oxygen species (ROS), and mitochondrial ROS by 16%, 71%, and 24% respectively. The inclusion of garlic as a functional ingredient helped relieve the presence and effects of AFB1.
本研究聚焦于使用添加或未添加新鲜沃吉耶拉大蒜(2%)的面包(天然受污染)来评估黄曲霉毒素B1(AFB1)的生物可及性和细胞毒性。进行了两项不同的实验:实验1(E1),使用低AFB1浓度的面包(1.6 - 1.7毫克/千克);实验2(E2),使用高AFB1浓度的面包(96.4 - 102.7毫克/千克)。制备了八种面包,四种用于E1(实验1),另外四种用于E2(实验2),每个实验都有一个对照组(C)、一个大蒜富集组(2%)(G)、一个AFB1组(A)和一个AFB1 + 大蒜组(A + G)。对每种面包进行模拟消化,得到胃消化液和肠消化液。通过高效液相色谱 - 荧光检测法测量面粉、烘焙面包以及胃和肠消化液中的AFB1含量。结果表明AFB1的生物可及性呈剂量依赖性,并且大蒜的存在有助于在两种剂量下降低其含量(7 - 8%)。此外,在受AFB1污染的面包中添加大蒜可提高分化的Caco - 2细胞的细胞活力(9 - 18%),减轻AFB1对Jurkat T细胞引发的S期和G2/M期阻滞,并分别使细胞凋亡/坏死、细胞活性氧(ROS)和线粒体ROS降低16%、71%和24%。将大蒜作为功能性成分添加有助于缓解AFB1的存在及其影响。
