Abstract (croatian)

Celer je povrće s malom kalorijskom vrijednosti i razmjerno malo vitamina no s brojnim zdravstvenim vrijednostima. Željezo je esencijalni element za biljke i za čovjeka zbog čega je nužno zadovoljiti potrebe njegovog dnevnog unosa oko 8-20 mg/dan. Cilj istraživanja bio je utvrditi količine željeza u korijenu celera korjenaša s obzirom na konvencionalni ili ekološki način poljoprivredne proizvodnje. Uzorci su prikupljeni u gradu Zagrebu u trgovačkim lancima, trgovinama ekološkim proizvodima i tržnici. Nakon razgradnje s koncentriranom HNO3 i HClO4 željezo je određeno pomoću AAS (atomskog apsorpcijskog spektrofotometra). Statistička obrada podataka provedena je prema metodi analize varijance (ANOVA). Količina željeza u suhoj tvari korijena celera korjenaša kretala se od 39,68 do 68,11 mg Fe/kg ST, odnosno od 0,44 do 0,71 mg Fe/100 g svježe tvari.

Abstract (english)

Celery is a vegetable with low calories and low content of vitamins, but has many good benefits on health. Iron is an essential microelement for plants and for humans too. Therefore, it is necessary to satisfy RDA (Recommended Dietary Allowance) uptake of 8-20 mg/day. The goal of present research was to determine the celeriac iron content regarding conventional and ecological agricultural production. Samples were taken in city of Zagreb in chain stores, stores with organic products and markets. After digestion with concentrated HNO3 and HClO4, iron was determined by AAS (Atomic Absorption Spectroscopy). Statistical data analysis was performed using Analysis of variance method (ANOVA). Iron celeriac content ranged from 39.68 to 68.11 mg Fe/kg DW, and from 0.44 to 0.71 mg Fe/100 g fresh weight.
