Innovative ultrasound-assisted approaches towards reduction of heavy metals and Iodine in macroalgal biomass 2021 Access copy available to the general public Unrestricted The aim of this work was to evaluate the potential of ultrasound (US), alone or in combination with mild heating and/or EDTA towards reduction of As, Cd, I, and Hg content of Laminaria hyperborea. Concentrations of As, Cd, I, and Hg of 56.29, 0.596, 7340, and <0.01 mg kg−1 of dry weight, respectively, were found in L. hyperborea blades. Treatment with US at 50 °C increased approx. 2-fold the amount of As released, although did not affect significantly the content of Cd or I, as compared to control (no US) samples. Reducing the temperature to 8 °C significantly decreased the effect of US, but heating at 80 °C did not cause a significant effect as compared to treatments at 50 °C. On the other hand, treatment with 0.1 N EDTA at 50 °C enhanced the percentage of Cd released by approximately 7-fold, regardless of sonication. In the present work, the combination of US and EDTA at 50 °C for 5 min led to a significant reduction of the As (32%), Cd (52%) and I (31%) content in L. hyperborea, thus improving the product’s safety for consumers. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 5.561 2021 FOOD SCIENCE & TECHNOLOGY 35 / 144 = 0.243 2021 Q1 T1 0.726 2021 Food Science 2021 Q1 Plant Science 2021 Q1 Microbiology 2021 Q1 Health Professions (miscellaneous) 2021 Q1 4.1 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Sone, I.
