Przedmiotem badań było zachowanie się współczynnika redoks rH naturalnej wody Źródlanej rozlewanej w opakowania jednostkowe ze szczególnym uwzględnieniem zastosowanych w procesie technologicznym metod uzdatniania wody (odżelaziania, odmanganiania, filtracji, saturacji CO2) oraz czasu i warunków jej przechowywania w- oraz po okresie przydatności wody do powszechnego spożycia.

Studied was the influence of the separate stages of a natural spring water preparation to the pouring in single packings as well as the the bottled water preservation period to the redox potential of the water. The water samples were picked up in different points of the production process: directly from the source after the iron separation, after filtration, after the manganese separation, after CO2 saturation, and on the end to the pouring process. The samples were also picked up from the water soon after the pouring to single packings, from the water preserved during limited period of utility for consumption and the water beyond the utility limits. There were also determined the factors dependent on redox potential of the examined water like: the hydrogen ion activity (pH), the colouring, the dullness, the electrical conductivity, consument oxygen (ChZT), the content of the iron and manganese. The changes of oxidation and reduction properties observed on the particular stages of the production are dependent on the air presence and on the presence of CO2 in the final stage. In course of the bottled water preservation were observed the reduction of the redox rH coefficient value that is potential redox and the water pH function.
