ABSTRACT
Contemporary science has confirmed that silver is one of the most powerful natural antimicrobial agents which can destroy more than 650 species of known pathogen microorganisms. Very high technological demands in the production of colloids and ionized particles are responsible for the fact that silver is used for water disinfection only in the most developed countries. Therefore, proverb in the west says 'silver is not the privilege of wealth, but of health'. The aim of the research was to examine the efficiency of the disinfectant SANOSIL SUPER 25® used for 0.5 liter PET bottles washing in the process of the bottling of the carbonated soft drink 'Orange ROSA'. This multi-component disinfectant (based on silver and hydrogen peroxide) was used in concentrations of 40 ppm. After the washing of the PET bottles in the machine 'Bluestar-Simonazzi' a standard bacteriological examination of 192 bottle samples was performed. In none of the examined samples could the presence of bacteria be discovered. The results of the examination of the chemical content of bottled orange soft drink indicated that the concentration of silver was within lawful limits. Based on all acquired results the conclusion is that SANOSIL SUPER 25®, with concentrations of 40 ppm, may successfully be used as a disinfectant used in the preventive washing of PET bottles to be used for the bottling of the carbonated soft drink 'Orange ROSA'.
