Evaluation of the Effect of Thermal Processing in Total and Bioaccessible Content of Trace Elements in a Regional Crab from the Brazilian Northeast.

ABSTRACT: This study evaluated the total and bioaccessible content of essential and potentially toxic elements in crabs of the Ucides cordatus species subjected to cooking. In natura and processed samples from different locations in Ceará were analyzed. For this, acid digestion in a microwave oven using 7.0 mL of 65 w w^-1 HNO₃ was used for quantification of total elements. A CRM NIST 1568b (Oyster Tissue) was used for trueness evaluation and obtained recoveries between 94 and 103%. An in vitro gastrointestinal digestion method adapted from INFOGEST 2.0 was used to obtain the bioaccessible content of the minerals Al, As, Ca, Cu, Fe, K, Mg, Mn, Se, and Zn, respectively, by ICP OES. The results revealed relevant concentrations of essential minerals in the total contents of
