Abstract
Mrkva (Daucus carota L.) je dvogodišnja povrtna kultura koja u prvoj godini vegetacije razvija zadebljali korijen koji je namijenjen tržištu i preradi. Minerali zastupljeni u korijenu su kalij, kalcij, željezo, fosfor i jod. Kalij je alkalni metal velike rasprostranjenosti u prirodi. Kalij aktivira rad enzima i regulira permeabilnost živih membrana. Nedovoljan unos kalija u ljudski organizam hranom rijetko može uzrokovati njegov nedostatak. Cilj ovog diplomskog rada bio je utvrditi razlike u količini kalija u korijenu mrkve na tržištu grada Zagreba i međusobno ih usporediti s obzirom na mjesto kupnje i način proizvodnje. Uzorkovanje mrkve provodilo se na 15 prodajnih mjesta u gradu Zagrebu: 5 trgovina ekološkim proizvodima, 5 tržnica i 5 trgovačkih lanaca. Kalij je nakon digestije koncentriranom HNO3 i HClO4 u mikrovalnoj peći određen atomskom apsorpcijskom spektrometrijom. Količina kalija kretala se u rasponu od 1,45 do 3,29% K ST, odnosno od 129,89 mg K/100 g svježe tvari do 317,68 mg K/100 g svježe tvari.
Abstract (english)
Carrot (Daucus carota L.) is a two-year vegetable culture that in the first year of its vegetation develops thick root intended for market for fresh consumption or processing. Potassium, calcium, iron, phosphorus and iodine are minerals that can be found in carrot. Potassium is an alkaline metal highly distributed in nature. Potassium activates enzymes and regulates permeability of living membranes. Insufficient entry of potassium into human's organism by food can rarely cause its deficiency. The goal of this master's thesis is to determine the differences in the potassium content of roots of carrots on the market in the city of Zagreb and to compare them according to the place of purchase and production method. Carrot sampling was conducted on 15 selling spots in Zagreb: 5 organic products stores, 5 markets and 5 chain stores. After digestion of concentrated HNO3 and HClO4 in a microwave oven, potassium is determined by atomic absorption spectrometry. The amount of potassium ranged from 1,45 to 3,29% K in dry matter, or from 129,89 mg K/100g fresh matter to 317,68 mg K/100 g fresh matter.
