Sumario:The aim of this study was to evaluate the sensory quality attributes regarding soy oil (SO), and partially hydrogenated soy fat (PHSF) stability in potato frying process, according to the indicative discarding time parameters. The sensory testing included SO, PHSF, and French fries colour ranking, as well as the category scales to evaluate global quality and oxidation intensity of odor in SO and PHSF, and French friesodor and flavor, exhibited at different length of frying time. The total time of processing was 100 hours at temperature controlled to 180ºC +5. Sensory results revealed colour darkening in both SO and PHSF, and also a moderate oxidation odor in proportion to the increasing of frying time. The same tendency toward both oxidized odor and oxidized flavour in French fries samples was observed. No significant difference was observed in odor and flavour sensory quality in French fries prepared either in SO or PHSF.
