Avaliação das alterações físico-químicas e microbiológicas em amostra de água mineral retornável no período de validade

Abstract

In Brazil, the consumption of bottled water has been growing steadily, with increasing consumer quality control becomes increasingly strict. The paper aims to demonstrate the physical, physico-chemical and microbiological 20L mineral water in their 90-day validity. We collected three samples from the same lot, coming from filler located in the Campos Gerais region. In the physical-chemical analysis the composition was determined total solids, conductivity, pH, and other components. Comparing the results obtained with the parameters described on the product label. Microbiological analysis was evaluated changes heterotrophic and whether presence or absence of pathogens such as Clostridium perfringens, Pseudomonas amongst others. The values obtained were not significantly different, ie, the results are the standards set by RDC 173/06 da ANVISA.
