  "description": "<p>Aflatoxins (AFs) are produced mainly by the molds Aspergillus flavus and Aspergillus parasiticus. Aflatoxin<br>\nB1 (AFB1) is classified as carcinogenic to humans. The aim of this study was to evaluate the capacity of<br>\ndifferent strains of Lactobacilli (Lb.) and Bifidobacteria (Bf.) to reduce the bioaccessibility of AFB1 and<br>\naflatoxin B2 (AFB2), spiked in loaf bread, using a dynamic in vitro simulated gastrointestinal digestion<br>\nsystem. Aliquots of 20 mL of gastric and duodenal fluids were sampled for the determination of the<br>\nmycotoxins gastric and duodenal bioaccessibility respectively, by liquid-chromatography coupled to the<br>\nmass spectrometry in tandem (LC&ndash;MS/MS). A reduction of AFs bioaccessibility compared to the control<br>\n(digestion without bacterial strains) was evidenced. The strains that evidenced the highest gastric and<br>\nduodenal bioaccessibility reductions of AFB1 and AFB2 were Lb. johnsoni CECT 289, Lb. reuteri CECT 725,<br>\nLb. plantarum CECT 220 and Lb. casei CECT 4180, with values ranging from 76.38 to 98.34% for AFB1 and<br>\nfrom 77.14 to 98.66% for AFB2. These results suggest that a food enriched with specific probiotic<br>\nmicroorganisms and consumed at the same time as food contaminated with AFs, could reduce the risk<br>\nassociated to the intake of these toxic compounds contained in food.</p>",
