Abstract (croatian)

Celer je povrće koje se odlikuje visokom nutritivnom i zdravstvenom vrijednosti. Fosfor je u ljudskom organizmu od iznimne važnosti za žuč, bubrege i probavu. Dnevna potreba u ljudskoj ishrani za fosforom kod odraslog čovjeka iznosi 700 mg. Cilj ovog istraživanja bio je utvrditi količine fosfora u korijenu celera korjenaša prikupljenom na tržištu grada Zagreba. Uzorkovanje je provedeno 2016. na dvije tržnice, u dva trgovačka lanca i u dvije trgovine ekološkim proizvodima. Uzorci su sušeni na 105 °C do konstantne mase nakon čega su mljeveni i homogenizirani. Nakon razgradnje s HNO3 i HClO4 fosfor je određen spektrofotometrijski. Rezultati istraživanja pokazali su znatno variranje u količini fosfora u korijenu celera, u suhoj tvari od 0,50 do 0,93% P, a u svježoj tvari od 67 do 90 mg P/100 g svježe tvari, ovisno o prodajnom kanalu. Konzumacijom 100 g celera iz ovog istraživanja može se podmiriti od 9,8 do čak 12,8%. dnevnih potreba za fosforom.

Abstract (english)

Celeriac is a vegetable of high nutrititve and health value. In human body, phosphorus is very imoprtant for bile, kidneys and digestion. The daily requirement in human nutrition for an adult is 700 mg of phosphorus. The aim of this research was to determine the phosphorus content of celeriac sampled on the market of Zagreb. Celeriac sampling was carried out in 2016 on 2 markets, in 2 market chains and in 2 stores with organic products. The samples were dried at 105 °C to a constant mass, after which were ground and homogenized. After digestion with HNO3 and HClO4 phosphorus was determined spectrophotometrically. The results of the research showed a significant variation in celeriac phosphorous content, in the dry weight from 0.50 to 0.93% P, and in the fresh weight from 67 to 90 mg P/100 g. By consuming 100 g of celeriac from this study 9.8 to 12.8% daily phosphorus needs can be satisfied.
