| Title : | DETERMINATION OF MINERAL CONTENT IN CRANBERRIES (Vaccinium microcarpum) AND THEIR INFUSIONS CONSUMED IN KOSOVO |
| Abstract : | After water, tea is the most widely consumed beverage in the world. In addition to its use as a beverage, tea is also known as a beverage that can have several health benefits, mainly due to the presence of nutrients. But, on the other hand, even very low concentrations of some metals can be toxic and can cause disorders and serious biological diseases. In this paper we have researched the content of micro and macro elements in chamomile tea samples of five different brands: sample 1 (Croatia), sample 2 (Kosovo), sample 3(Sri Lanka), sample 4 (Slovenia) and sample 5 (Kosovo) found in a local market in Pristina. Concentrations of the elements were determined by the method of atomic absorption spectroscopy (AAS). Microwave was used to decompose samples. Concentrations of metals in chamomile samples were: Na (1908-2480 mg/kg), K (3860-9294 mg/kg), Ca (11972-24269 mg/kg), Mg (1309-4287 mg/kg, Zn (10-33 mg/kg), Fe (86-302 mg/kg), Mn (69-217 mg/kg) and Ni (2-5 mg/kg) On the other hand metal concentrations in infusions of chamomile tea of these five brands at different times (3, 5 and 10 minutes) were: Na (1131-2233 mg/kg), K (3147-8999 mg kg), Ca (9189-22140 mg/kg), Mg (935-3899 mg/kg, Zn (2.1-29 mg/kg), Fe (6-47 mg/kg), Mn (37-177 mg/kg) and Ni (1-2 mg/kg). Of all the macronutrients (Na, Mg, K and Ca), calcium had the highest concentration which ranges from 11972-24269 mg/kg. By comparing the concentrations of all heavy metals (iron, zinc, nickel and manganese) iron content was the highest of all samples, in the range of 86 mg/kg - 302 mg/kg. |
