Carrot (Daucus carota L.) is vegetable of Apiaceae family that has a very significant nutritional and health value in human nutrition. Furthermore, it is rich in elements that alkalize blood and keeps it at pH 7. Therefore, the aim of this research was to determine the content of soluble sugars and pH in carrot’s juice and to compare the results regarding to the place of purchase. Carrot sampling was carried out in triplicate in city of Zagreb (Croatia) in 5 retail chains, 5 markets and 5 organic products stores. Soluble sugar content (% Brix) from the percolated juice was determined by refractometer, while the pH of the juice was determined by pH meter. The content of soluble sugar ranges between 6.47 and 10.13% Brix (average 7.43 in supermarkets, 7.95 in markets and 8.54 in organic shops). The pH of the carrot juice ranges from 6.17 to 7.02 (average 6.69 in supermarkets, 6.65 at markets and 6.55 in organic shops).
