Effects of various cooking methods and food components on bioaccessibility of mercury from fish

Influence of bioaccessibility of total mercury, methyl-mercury and selenium on the risk/benefit associated to the consumption of raw and cooked blue shark (Prionace glauca)

“…Therefore, MeHg concentration represents percentages above 80% of total Hg level, which is in accordance with EFSA (2012). As in this study, several authors reported that culinary treatments usually lead to an increase in Hg levels due to water loss (Burger et al, 2003;Perelló et al, 2008;Maulvault et al, 2011;Quédraogo and Amyot, 2011;Costa et al, 2013). According to Burger et al (2003), Hg present in fish muscle does not seem to be significantly released during the culinary treatment, probably remaining bound to proteins.…”

Changes in fatty acids, sterols, pigments, lipid classes, and heavy metals of cooked or dried meals, compared to fresh marine by-products

“…Heavy metals might be reduced during the process applied because the heat causes denaturation of methaloproteins and de-methylation that reduces the bio-accessibility of metals (Ouédraogo and Amyot, 2011), and during cooking these free metals can be leached to the cooking broth. This can be a desirable effect for mollusks in general, that tend to be enriched in mercury and cadmium Raimundo et al, 2014) and more so viscera that contain metabolic active tissues that function as kidney and liver.…”

Bioaccessibility of mercury in selected Ayurvedic medicines

“…In the present study, the gastric phase was the simplest and most dilute with respect to organic carbon content, compared with the other extracting solutions. The methylmercury may have become well-adsorbed to the bile and pancreatin introduced in the intestinal phase of the PBET, and possibly removed by the centrifugation and filtration step if adsorbed to particles larger than 0.45 μm, similar to the effect of organic chemicals in other studies (e.g., He and Wang, 2011;Ouédraogo and Amyot, 2011). The organic components of the extracting solutions appear to have the opposite effect on inorganic mercury, which is found in relatively insoluble forms (as cinnabar) in the medicine samples.…”
