M. aAnalytical strategies and method validation to access the bioavailability of essential elements and arsenic from raw and cooked fish and shrimp.h[electronic resource] c2023 ap. 1229-1237. aThe bioavailability of essential and toxic elements in raw/cooked tilapia and shrimp was estimated using in vitro gastrointestinal digestion followed by the Caco-2 cell model to simulate the human intestinal barrier. Analytical strategies such as aerosol dilution, collision cell, and matrix-matching calibration were successfully explored for multielement quantification using ICP OES and ICP-MS. From Caco-2 cell bioassays, the estimated bioavailability values ranged from 1.4% (Fe) to 15.2% (Cu) in tilapia and from 0.2% (Fe) to 10.7% (P) in shrimp. Air-frying and oven-baking methods decreased tilapia’s Mg, P, S, Cu, and Fe bioavailability. Contrarily, the bioavailability of essential elements (except Mn) in shrimp seemed to increase after air-frying. Arsenic bioavailability in cooked shrimp was significantly higher than in the raw sample (1.9 vs 5.7%) but fortunately below the limit allowed by legislation. In spite of the complexity of basal solutions from the cell-based bioassays, the applied analytical strategies allowed the accurate quantification of the bioavailable fractions by ICP-based methods. aAnalytical strategies aCaco-2 cells aIn vitro uptake aThermal treatments1 aNICIURA, S.
