The aim of this paper is to evaluate the peroxide value (PV) of different alimentary oils, as well as to determinate the number of yeasts and molds that develops in this oils. Fungi value is an indicator that ensure the sanitation of samples. Also for refined sun flower oil, the oxidation rate of the samples exposed to daylight or kept in darkness was followed for 60 days. PV exceeds the maximum recommended value of 10 meq/kg after 45 days for sunflower oil exposed to daylight. The samples stored in the dark reached the value of 8.68 mEq/kg at the end of the investigation period. Oxidative rate of used refined sunflower oil subjected to frying temperatures (1700C) was motorized during heat treatment, finding a rapid increase in PV at 18.32 meq/kg after 60 minutes.
