Resumen en inglés

The implementation of disinfectants in food plants is an important aspect to guarantee safe sanitation in their process areas. The food processing plant in Planeta Rica has 3 disinfectants: Titan Plus 15% used in the areas of pasteurization, Butter and UHT, Biquat in the areas of pasteurization, spraying and butter, citrosan in the cafeteria area. These are prepared in said areas by the sanitizers. However, these do not have a reliable tool to determine the concentration. For which, several non-conformities have been generated in the plant during previous audits. For this reason, the quality control area at the Planeta Rica food processing plant proposed the objective of electrometrically and microbiologically evaluating Titan disinfectants, S. aureusATCC 25923, Klebsiella aerogenes ATCC 13048 and Candida albicans ATCC 10231. The assay turned out to be efficient because the calibration curves were a formidable tool, being the R2 of Biquat the highest 0.996. The results of the electrometric, microbiological monitoring and the antimicrobial evaluation correlated enough to suggest that the Titan Plus 15% is the only disinfectant that shortens its changeover time from 8 to 4 hours.
