| dc.description.abstract | Food provides nutrients, but also antinutritional components and contaminants. This raises the issue of quantifying the risks associated to a given food. Since the gastrointestinal tract is the most frequent route for food contaminants exposition, the impact of food contaminants in the digestive process, their effects in the intestinal barrier integrity and how these compounds would be available and absorbed must be well characterized and known. Patulin (PAT) is a mycotoxin produced by different species of Penicillium, Aspergillus and Byssochlamys that can be found in fruit and fruit products, mainly apples and apple products. This work aimed to study, for the first time, PAT’s bioaccessibility in cereal and fruit based baby foods through the harmonized in vitro digestion method developed on the INFOGEST network. For bioaccessibility determination, patulin was identified and quantified by HPLC-UV with Solid Phase Extraction (SPE). Commercial cereal and fruits based baby foods, previously checked not to be contaminated with PAT, were artificially contaminated to 20 µg/kg of patulin and presented bioaccessibility values ranging from 42 % to 65 %. These results are consistent to those reported by Brandon et al. (2006) who referred a bioaccessibility for patulin ranging from 55 % to 100 % in apple products. These results are higher than those previously reported by Assunção et al. (2014) for apple juices, with a mean value of 28%. These are the first preliminary results on patulin bioaccessibility in cereal and fruit based baby foods, using the harmonized in vitro digestion method developed by the INFOGEST network. | por |
