Sažetak
Zinc and iron deficiencies in children are well documented in developing countries, but there is also a non negligible percentage of infants in developed countries with too less intake of these two micronutrients. Especially complementary feeding proposed during the first year of breastfed children does not meet the micronutrient needs. Thus insufficient intake of iron and zinc is a global issue. Zinc malnutrition is together with vitamin A deficiency the most serious micronutrient deficiency. Various fruit and vegetable juices recommended for children older than four months are commercially available and recommended as complementary feeding, some of them having elevated levels of essential elements, such as iron. Thus a study of the elemental composition of children juices on the European market is an important contribution to the investigation of children´s nutrition and potential deficiencies. A wide range of commercially available children juices, like apple, carrot, pear juices were analyzed for their iron and zinc content. The juices were diluted 1:20 with 2% HNO3 prior to measurement by inductively coupled plasma optical emission spectrometry (ICP-OES). The concentrations found range from 0.22 mg/L to 2.55 mg/L (median 0.88 mg/L) for iron and 0.11 mg/L to 1.75 mg/L (median 0.90 mg/L) for zinc. Thus some juices with higher iron and zinc content can be recommended as useful complementary feeding.
