Abstract
In recent decades, the demand for the consumption of bottled drinking water has been increasing. Drinking water is an irreplaceable food product in human nutrition, therefore, in addition to processing, permanent quality control is also required. The object of the study in this paper was the analysis of several quality parameters in two types of bottled water in glass and plastic (PET). Sampling was carried out in the market of the city of Tetovo. The samples were analyzed for qualitative parameters: sensory (color, aroma, taste), physical and chemical (pH, turbidity and electrical conductivity). The results obtained in the analyzed samples showed that they are identical to those declared on the packaging label, although the water was from the same source, there were differences in the results for the analyzed parameters, but they were minimal. Sensory parameters as in the sample in plastic and glass packaging, the color was characteristic for drinking water without foreign color, the aroma without odor and without foreign taste, the pH level was almost identical between the analyzed samples with very small deviations. Based on the electrical conductivity and turbidity in the analyzed water samples, the water packaged in glass had lower values and better quality results.
