ABSTRACT

The purpose of this study was to evaluate the impact of freezing and heating storage on the physicochemical properties (EC, pH, Alkalinity, Hardness, TDS, Ca+2, Mg+2, Na+, K+, and NO3-2) that make four different types of bottled water (Al-Hayat, Zalal, Sky water, and Masafy) suitable for drinking. The physicochemical parameters of the bottled water measured in this study were compared to the manufacturer’s labeling found on the bottles as well as to the WHO and IBWA standard guideline values. The results indicate, the physicochemical properties of all bottled water samples are within the international guidelines of bottled water and not the same that reported on the bottle label. The results show each of heating exposure and freezing of storing cause changes in all physicochemical properties of water in the plastic bottle.
