Iodine content was determined in 124 different French Polynesian food samples using inductively coupled plasma-mass spectrometry after alkaline digestion. For samples containing starch, the method was optimised by including an additional enzymatic treatment step. This analytical method was validated with an accuracy profile approach, using certified reference materials with iodine contents ranging from 0.027 to 4.95mgiodinekg(-1) dry weight. The trueness bias ranged from -5.8% to 22.4% and the highest observed intermediate precision coefficient of variation CVR was 11% in starchy materials. Tested Polynesian foods showed large variation in iodine content, with values of 0.014-0.032mgkg(-1) for fruits, 0.014-0.081mgkg(-1) for starchy samples, 0.027-1.85mgkg(-1) for green vegetables, 0.222-5.19mgkg(-1) for fish, 6.51-85.6mgkg(-1) for shellfish, and 0.004-1.39mgkg(-1) for beverages.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-31796","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"University of Paris-Est, Anses, Maisons-Alfort Laboratory for Food Safety, Department of Chemical Contaminants in Food, Metallic Trace Elements and Minerals Unit, Maisons-Alfort, France.
