Iodine content in eggs

The aim of diploma work was contents supervision iodine solution in egg yolk in the consumer eggs and evaluates importance of eggs as an iodine source in human nutrition. In total, iodine content was determined in the yolk of 189 eggs (large flocks) and 210 eggs (small flocks). There were 3,2 times lower of iodine content in the egg yolk from small flocks compare to eggs from large flocks. Eggs from large flocks cover 2 - 25% and from small flocks only 0,4 {--} 12% of the daily iodine requirement in adults. Iodine content in eggs depends on daily iodine intake and the effect of laying cycle. Egg iodine concentration was determined by spectrophotometric metod based on the Sandell-Kolthoff reaction (Bednář a kol. 1964)
