Abstract

Celer je povrće koje obiluje vitaminima i eteričnim uljima, a za ovo istraživanje odabran je korijen celera korjenaša. Fosfor je u ljudskom organizmu od iznimne važnosti. Dnevna potreba u ljudskoj ishrani za fosforom kod odraslog čovjeka je 700 mg. Cilj ovog istraživanja bio je utvrditi količine fosfora u korijenu celera prikupljenim na tržištu grada Zagreba. Uspoređivani uzorci iz ekološke i konvencionalne proizvodnje prikupljeni su na pet različitih lokacija, te dostavljeni u Laboratorij Zavoda za ishranu bilja Agronomskog fakulteta. Uzorci su sušeni u sušioniku na 105 0C 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 količinama fosfora 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.

Abstract (english)

Celeriac is a vegetable rich in vitamins and essential oils, and for this research its root was used. In human body, phosphorus has a great value. The daily requirement in human nutrition for an adult is 700 mg of phosphorus. The aim of this research was to determine the celeriac phosphorus content sampled on the market of Zagreb. The samples that were compared of organic and conventional production were collected at five different locations and taken to the Laboratory of Department of Plant Nutrition of the Faculty of Agriculture. The samples were dried in a drying oven at 105 °C to a constant mass, after which were ground and homogenized. After digestionwith 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.
