Iodine content in the pool samples milk

Abstrakt The work deals with the content of iodine in pools samples cow's milk. It provides information about the content of iodine in the Czech Republic within years and districts. Milk was obtained in collaboration with Madeta a.s. Iodine was subsequently determined by spectrophotometry after alkaline combustion of the sample (Sandell-Kolthoff method). A total were evaluated of 149 samples milk (2013-2015). In 2013, the average iodine content in bulk milk samples 289,3 gl-1. In 2014, the average iodine content in bulk milk samples 222,2 microgram.l-1. In terms of food source of iodine in the milk TRÁVNÍČEK et al. (2011) reported the optimal value for the content of iodine in the milk of between 100 to 200 microgram.l-1. The results are thus slightly higher than the optimum. Within the districts was found the highest average in 2013 in the district of Tábor (398,0 microgram.l-1). The highest average content measured in 2014 was found in the district Prachatice (357,0 microgram.l-1), while the lowest average value measured was found in the district Třebíč (163,0 microgram.l-1)
