Abstract
Patvorenje mlijeka predstavlja značajan problem u mljekarskoj industriji. Definira se kao svako naknadno dodavanje strane tvari ili izdvajanje postojećih sastojaka iz mlijeka, a predstavlja rizik za zdravlje potrošača i neprikladnost daljnje prerade mlijeka u mliječne proizvode. Za otkrivanje patvorenja mlijeka koriste se razne metode, a jedna od njih je spektrofotometrijska metoda. Cilj rada je dokazati prisutnost Na‐bikarbonata (NaHCO₃) u mlijeku MID‐infracrvenom FTIR spektrofotometrijskom metodom, na instrumentu Milkoscan FT3 (Foss Electric, Danska). U radu su analizirana 62 uzorka kravljeg mlijeka u koje je dodano (eng. w/v) 0.09%, 0,19% i 0,29% NaHCO₃ u bočice volumena 50 mL. Prema dobivenim rezultatima zaključuje se da je spektrofotometrijska metoda na instrumentu Milkoscan FT3 pogodna za dokazivanje prisutnosti Na‐bikarbonata (NaHCO₃) u mlijeku.
Abstract (english)
Milk adulteration is present in the world’s dairy industry. It is defined as any subsequent addition of a foreign substance or its extraction from the milk. It presents a problem because of consumer health risks and the impossibility of further processing the milk into dairy products. Various methods are used to detect milk adulteration, and one of them is the spectrophotometric method. The experimental part of this graduate thesis is based on proving the addition of sodium bicarbonate in milk by MID‐infrared FTIR spectrophotometric method on Milkoscan FT3 (Foss Electric, Denmark) instrument. In total 62 (50 mL) samples of cow's milk were analyzed. The samples were adulterated with 0.09%, 0,19% i 0,29% NaHCO₃ (w/v). According to the results, it is concluded that the spectrophotometric method on Milkoscan FT3 is suitable for discovering milk adulteration with sodium bicarbonate (NaHCO₃,).
