AB  - In order to control the quality of beer and raw materials for production of beer in Belgrade Beer Industry (BIP), water is analyzed (city, technological and demineralized water). Measurements of pH values indicated the increased pH values in the sample of technological water, which had no impact on wort hopping, since the tested samples of wort, young beer and final product had a pH value within the expected range. After processing city water, a sample of technological water was found with increased carbonate hardness, which is caused by the increased content of sodium hydrogen carbonate. Analysing the titration alkalinity, titration acidity and buffering power, it was found that the alkalinity was decreasing which is in accordance with the determination of pH values of wort and beer samples (young beer and final product). Analyzing the content of anions and cations in the examined water samples, it has been shown that the concentration of these examinated anions (Cl-, NO3-, SO42- and PO43-) and cations (NH4+, Na+, K+, Ca2+, Mg2+) are within the limits prescribed by the Regulations on hygienic safety of drinking water, and thus by the Regulations of quality and other requirements for beer. The contents of anions in wort and beer samples (young beer and final product) were determined by ion chromatography method. The contents of sulphate and nitrate ions were within the recommended limits. The concentration of chloride ions was above 150 mg/dm3, which may have an impact on the sensory properties of beer, while changes in the content of phosphate ions were insignificant.
AB  - U cilju kontrole kvaliteta piva i sirovina za proizvodnju piva u Beogradskoj industriji piva (BIP) analizirana je voda (gradska, tehnološka i demineralizovana). Merenja pH vrednosti ukazala su na povećanu vrednost pH u uzorku tehnološke vode, ali to nije imalo uticaja na ukomljavanje slada pošto su ispitivani uzorci sladovine, kao i uzorci mladog piva i gotovog proizvoda imali vrednost pH u očekivanom opsegu. Obradom gradske vode dobio se uzorak tehnološke vode sa povećanom karbonatnom tvrdoćom, koja je prouzrokovana povećanim sadržajem natrijum-hidrogenkarbonata. Analizom titracionog alkaliteta, titracionog aciditeta, i moći puferovanja, utvrđeno je da se alkalitet smanjuje što je u saglasnosti i sa određivanjem pH vrednosti uzoraka sladovine i piva (mladog i gotovog proizvoda). Analiza sadržaja anjona i katjona u ispitivanim uzorcima vode, pokazala je da je koncentracija ispitivanih anjona (Cl-, NO3-, SO42- i PO43-) i katjona (NH4+, Na+, K+, Ca2+, Mg2+) u granicama propisanim Pravilnikom o higijenskoj ispravnosti vode za piće, a time i sa Pravilnikom o kvalitetu i drugim zahtevima za pivo. Sadržaj anjona u uzorcima sladovine i piva (mladog i gotovog proizvoda) određen je metodom jonske hromatografije. Sadržaj sulfat- i nitrat-jona je bio u preporučenim granicama. Koncentracija hlorid-jona je bila iznad 150 mg/dm3, što može imati uticaja na senzorne karakteristike piva, dok je promena sadržaja fosfat-jona bila neznatna.

AB  - In order to control the quality of beer and raw materials for beer production, methods as ion chromatography (IC) and atomic absorption spectrophotometry (AAS) were applied. Water was analyzed as a raw material for beer production (urban, technological and demineralized water). Measurements of pH values indicated the increased pH values in the sample of tehnological water, but it had no impact on wort hopping, since the tested samples of wort, young beer and final product had a pH value in the expected range. Analyzing the content of anions and cations in the examinated water samples, it is shown that the concentration of these examinated anions (Cl- , NO3-, SO42- and PO43-) and cations (NH4+, Na+, K+, Ca2+, Mg2+), as and microelements (Fe, Cu i Zn) are within the limits prescribed by the Regulations on hygienic safety of drinking water and the Regulations of quality and other requirements for beer. Investigating contents of anions in samples of wort and beer (young beer and final product) showed that the contents of SO42- and NO3- ions were within recommended limits and the concentration of Cl- ions was above 150 mg/dm3, which may have an impact on sensory characteristics of beer, while changes in the content of PO43- ions were insignificant. Since AAS method is a standard method for analyzing content of alkaline and alkaline earth metals, the results obtained by this method in beer samples are taken as a referent results and according to them an analyse was performed and results obtained by IC method were compared. Results of the determination of Na, Ca and Mg in examinated water samples have shown variations, but both methods have shown the increased content of Na in demineralized water. The contents of alkaline and alkaline earth metals in wort and beer (young beer and final product) have shown that the results obtained by these two methods were in agreement.
AB  - U cilju kontrole kvaliteta piva i sirovina za proizvodnju piva u Beogradskoj industriji piva (BIP) primenjene su metode jonske hromatografije (IC) i atomske apsorpcione spektrofotometrije (AAS).

Ispitivanje sadržaja anjona u uzorcima sladovine i piva (mladog i gotovog proizvoda) pokazalo je da je sadržaj SO4 2-- i NO3 --jona bio u preporučenim granicama, koncentracija Cl-- jona bila je iznad 150 mg/dm3, što može imati uticaj na senzorne karakteristike piva, dok je promena sadržaja PO4 3--jona bila neznatna. Pošto je AAS standardna metoda za analizu sadržaja alkalnih i zemnoalkalnih metala, rezultati dobijeni ovom metodom u uzorcima piva uzeti su kao referentni i prema njima je izvršena analiza i upoređivanje rezultata dobijenih metodom IC. Rezultati određivanja Na, Ca i Mg u ispitivanim uzorcima vode, pokazala su odstupanja, ali su obe metode ukazale na povećan sadržaj natrijuma u demineralizovanoj vodi. Sadržaj alkalnih i zemnoalkalnih metala u uzorcima sladovine i piva (mladog i gotovog proizvoda) ukazao je da su rezultati dobijeni ovim dvema metodama bili u saglasnosti.
