Sažetak
Carrot is a vegetable from the Apiaceae family. Carrot is of high importance in human diet because of its root's nutritive composition. Potassium, calcium, iron, phosphorus and iodine are minerals that can be found in carrot. Calcium is a widely spread element and has many physiological roles in plants and is also found in cellular organelles: mitochondria, chloroplasts and ribosomes. Calcium is an important soil constituent because it affects its pH value, availability of some elements and has an important role in maintaining the soil structure. In human organism, calcium is mainly found in structure of bones and teeth. It participates in several physiological processes: muscle contraction, transmission of nerve impulse, blood pressure control and it also prevents osteoporosis in elderly people and rickets in children along with vitamin D. Often, consumers do not know what they are buying, and research has been carried out to determine the amount of calcium in the orange colored carrot root and compare the results with regard to the place of purchase. Carrot sampling was conducted on 15 selling spots in Zagreb: 5 market chain branches, 5 market places and in 5 stores with ecological products. After digestion of concentrated HNO3 and HClO4 in a microwave oven, calcium was determined by atomic absorption spectrometry. The amount of calcium ranged from 0.25% to 0.57% Ca in dry matter, ie 22.02 to 63.35 mg Ca 100 g-1 in fresh matter. In general, the highest calcium values were found in carrot root samples (0,41% Ca in dry matter and 41,31 mg Ca 100 g-1 in fresh matter).
