PHYSICO-CHEMICAL, MICROBIOLOGICAL AND PHARMACOLOGICAL STABILITY OF THERAPEUTIC MINERAL WATERS

Abstract

Introduction: For a natural mineral water to be bottled and then sold as table water, besides some physicochemical characteristics that define it, must come from a natural source (spring, well, borehole) with a high purity biological and microbiology. Most chemical compounds, expressed major elements, trace elements, gases, some undissociated compounds closely correlated with water temperature and pH they have a role in assessing qualitative characterization and classification of mineral waters. Variety composition of mineral water generated their many uses in both the therapeutic and the water table. Physico-chemical composition and microbiological indicators values for drinking must belong to a high degree of stability for certain periods of time. Degree of physical and chemical stability of mineral waters in general is closely related to chemical equilibrium achieved naturally when water does not undergo any transformation (being bottled just by adding carbon dioxide), or may undergo significant changes technological processes (deferizare, desulfurization, degassing, etc.). Use bottled mineral water is provided in the form of national and international rules that limit technological operations and treatments that could influence the initial natural features. For this purpose were admitted as necessary to ensure stability operations only bottled mineral water deferizarea and impregnation with carbon dioxide. Objectives: LIAMNT lab has pursued stability physicochemical, microbiological and pharmacodynamics over a period of 6 months or 1 year of several types of bottled mineral water (oligomineral water, carbonated water, sulfur water, etc).
